Chlorosplenium is a small genus comprising five species of inoperculate discomycetes in the order Helotiales (Leotiomycetes) often recognizable by their bright yellowish-green colors and gregarious growth on wood. In this study, we describe five new species-C. aotearoa, C. australiense, C. cusucoense, C. epimorsicum, and C. hawaiiense-based on a combination of recent fieldwork and examination of previously collected fungarium specimens. We use an integrative taxonomic approach to support the distinction of new species, incorporating morphology and DNA sequence data with biogeography. Macro- and micromorphological features of apothecia for all species and culture characteristics for four of the five new species are documented. A multilocus phylogeny based on nuc rDNA internal transcribed spacer region ITS1-5.8S-ITS2, partial large subunit nuc ribosomal DNA (28S nuc rDNA), and A-B regions of the largest subunit of RNA polymerase II (RPB1) gene is presented. Additionally, we report Chlorosplenium chlora from Europe for the first time and expand our knowledge of the diversity and distributions of species in this genus in America, Australia, and New Zealand.

Simple Summary: Feather mites are a specific group of ectoparasites or commensals of almost all bird species worldwide, morphologically and biologically adapted to function in a very unusual environment—the plumage of their hosts. They are able to attach themselves so strongly to feathers that they do not leave their hosts even after their death, remaining on or in the feathers as dried 'mummies'. This makes it possible to discover and describe them by viewing birds preserved in museum collections. Of the currently known approximately 2500 species of feather mites, the vast majority are derived from just such a source of material. Also, the species described in this paper, new to knowledge, Grallolichus heliornisi sp. n. (Pterolichidae), comes from an old exhibition specimen of the sungrebe (Heliornis fulica) from the family finfoots (Heliornithidae), found in the collection of the Zoological Museum in Kiel (Germany). This is the first record of a representative of this genus on finfoots and the first description of a new species for Grallolichus in more than 50 years. The diagnosis of the new species is based on a detailed analysis of the morphology, complemented by a key to the species known so far, and summarized through a reflection on the importance of old ornithological collections for understanding the biodiversity and evolution of feather mites. Feather mites of finfoots (Heliornithidae), a small gruiform family, are poorly and partly erroneously recognized. Grallolichus heliornisi sp. n. (Astigmata: Pterolichidae) is here described from the sungrebe Heliornis fulica as the first representative of the genus commonly found on close relatives of finfoots, Rallidae and Sarothuridae. This species belongs to the species group having ornamented dorsal shields and is morphologically most close to G. proctogamus inhabiting Eurasian coot (Fulica atra). Males of the new species differ from G. proctogamus mainly by the shape of opisthosomal lobes (triangular vs. rounded) and the aedeagus form (parallel sided vs. tapering distally). Females differ mainly by the shape of supranal concavity (open anteriorly vs. closed) and location of setae h1 in relation to supranal concavity (lateral vs. anterior). A key to known species of the genus Grallolichus is provided. The morphological analysis and descriptive characterization of this species, like much of the approximately 2500 feather mite species described to date, were based on mummified mite material preserved in 19th-century old museum bird specimens. These often-forgotten collections are the only source for the analysis of the acarofauna of many rare, unavailable wild or even extinct bird taxa. [ABSTRACT FROM AUTHOR]

Two novel Gram-stain-negative, aerobic, and non-motile strains, designated FZY0004T and YYF002T, were isolated from an agar-degrading co-culture, which was obtained from seawater of the intertidal zone of Yancheng City, the Yellow Sea of China. Strain FZY0004T optimally grew at 28 °C, pH 7.0, and 2–6% NaCl, while strain YYF002T optimally grew at 28 °C, pH 7.5, and 2–4% NaCl. Strain FZY0004T possessed Q-9 as the major respiratory quinone, and its major fatty acids (> 10%) were summed feature 8 (C18:1ω7c), C16:0, and summed feature 3 (C16:1ω7c/C16:1ω6c). The polar lipids identified in strain FZY0004T were phosphatidylethanolamine (PE), phosphatidylglycerol (PG), and several unidentified phospholipids (PL) and lipids (L). On the other hand, strain YYF002T had MK-6 as the predominant respiratory quinone and its major fatty acids consisted of iso-C15:0, iso-C15:1 G, and iso-C15:0 3-OH. The polar lipids identified in strain YYF002T were aminolipid (AL), PE, and several unidentified lipids. Strain FZY0004T shared 99.5% 16S rRNA gene sequence similarity and 90.1% average nucleotide identity (ANI) with T. povalilytica Zumi 95T, and strain YYF002T shared 99.2% 16S rRNA gene sequence similarity and 88.2% ANI with W. poriferorum JCM 12885T. The genomic DNA G + C contents of strains FZY0004T and YYF002T were 54.5% and 33.5%, respectively. The phylogenetic, phenotypic, and physiological characteristics permitted the distinction of the two strains from their neighbors, and we thus propose the names Thalassospira aquimaris sp. nov. (type strain FZY0004T = JCM 35895T = MCCC 1K08380T) and Winogradskyella marincola sp. nov. (type strain YYF002T = JCM 35950T = MCCC 1K08382T). [ABSTRACT FROM AUTHOR]

A Gram-stain-positive, strictly aerobic, creamy-white colored, endospore-forming and non-motile rods strain, designated as strain 2205SS18-9T, was isolated from a marine sponge, Axinella sp. collected from Seopseom Island, Republic of Korea. Optimal growth of strain 2205SS18-9T was observed at 25–30 °C, pH 6.5–7.0, and in the presence of 3.0% (w/v) NaCl. Cells were oxidase-positive and catalase-negative. Negative for nitrate reduction and indole production. Phylogenetic analyses based on the 16S rRNA gene and whole-genome sequences revealed that strain 2205SS18-9T formed a distinct phyletic lineage in the genus Chengkuizengella, and it was most closely related to Chengkuizengella marina YPA3-1-1T and Chengkuizengella sediminis J15A17T with 97.1 and 96.6% 16S rRNA gene sequence similarities, respectively. The average nucleotide identity and digital DNA-DNA hybridization values between strain 2205SS18-9T and Chengkuizengella marina YPA3-1-1T were 79.0 and 21.6%, respectively. The genomic DNA G + C content was 34.1%. The genome harbors a number of host-adhesion and transporter genes, suggested that strain 2205SS18-9T may interact with its sponge host as a symbiont. Menaquinone-7 was the sole isoprenoid quinone and antieiso-C15:0 (28.5%), iso-C16:0 (25.8%), C16:1ω7c alcohol (15.0%), and iso-C15:0 (11.2%) were detected as the major fatty acids. Polar lipids included diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, two unidentified aminophospholipids, and an unidentified lipid. The cell-wall peptidoglycan contained lysine, alanine, glutamate, and aspartate. Based on these analyses, strain 2205SS18-9T represents a novel species of the genus Chengkuizengella, for which the name Chengkuizengella axinellae sp. nov. is proposed. The type strain is 2205SS18-9T (= KACC 23238T = LMG 33063T). [ABSTRACT FROM AUTHOR]

The taxonomy of the Listeriaceae family has undergone substantial revisions, expanding the Listeria genus from 6 to 29 species since 2009. However, these classifications have relied on 16S rRNA gene sequences and conventional polyphasic taxonomy, with limited use of genomic approaches. This study aimed to employ genomic tools, including phylogenomics, Overall Genomic Relatedness Indices (OGRIs), and core-genome phylogenomic analyses, to reevaluate the taxonomy of the Listeriaceae family. The analyses involved the construction of phylogenetic and phylogenomic trees based on 16S rRNA gene sequences and core genomes from 34 type strain genomes belonging to Listeriaceae family. OGRIs, which encompass Average Amino acid Identity (AAI), core-proteome AAI (cAAI), and Percentage of Conserved Proteins (POCP), were calculated, and specific threshold values of 70%, 87%, and 72–73% were established, respectively, to delimitate genera in the Listeriaceae family. These newly proposed OGRI thresholds unveiled distinct evolutionary lineages. The outcomes of this taxonomic re-evaluation were: (i): the division of the Listeria genus into an emended Listeria genus regrouping only Listeria senso stricto species; (ii): the remaining Listeria senso lato species were transferred into three newly proposed genera: Murraya gen. nov., Mesolisteria gen. nov., and Paenilisteria gen. nov. within Listeriaceae; (iii): Brochothrix was transferred to the newly proposed family Brochothricaceae fam. nov. within the Caryophanales order; (iiii): Listeria ivanovii subsp. londonensis was elevated to the species level as Listeria londonensis sp. nov.; and (iiiii): Murraya murrayi comb. nov. was reclassified as a later heterotypic synonym of Murraya grayi comb. nov. This taxonomic framework enables more precise identification of pathogenic Listeriaceae species, with significant implications for important areas such as food safety, clinical diagnostics, epidemiology, and public health.

Crepidotus subg. Dochmiopus contributes to more than half of Crepidotus species and exhibits highly hidden diversity. However, C. subg. Dochmiopus is challenging to study because the basidiomata of C. subg. Dochmiopus species are usually small and white, inconspicuous interspecific distinctions, and possess a familiar complex. In this study, we utilized a variety of characteristics for species identification, including habitat, presence or absence of a stipe in mature specimens, pileipellis and cheilocystidia patterns, whether the lamellae edges are fimbriated, and other characteristics. Above all, cheilocystidia and pileipellis patterns will be important in C. subg. Dochmiopus research. Based on the present specimens, we constructed a multigene phylogenetic tree (ITS + LSU) and recognized four new species: C. lamellomaculatus sp. nov., C. capitatocystidiatus sp. nov., C. succineus sp. nov., C. clavocystidiatustustus sp. nov. Detailed morphological descriptions, photographs, line drawings and comparisons with closely related taxa for the new species are provided. The current phylogenetic analysis does not support the previously classifications, indicating that the classification of Crepidotus requires re-evaluation. But the existing molecular datasets and species' descriptions are insufficient to fully resolve the classification. Further integration of new gene segments and a comprehensive review of morphological characteristics will reveal a natural classification for Crepidotus. [ABSTRACT FROM AUTHOR]

Simple Summary: The extensive field work study between 2020 and 2023 led to the discovery of three new species of wood-inhabiting fungi; Tropicoporus pannaensis, Tropicoporus subindicus, and Tropicoporus xerophyticus from the southern part of India. The detailed descriptions and illustrations along with molecular support are presented. These discoveries may contribute to our understanding of species diversity and ecology, ultimately benefiting the society by informing the conservation efforts and exploring the potential biomolecules. This study aimed to investigate the morphological characteristics and phylogenetic relationships of three new species of Tropicoporus from the southern parts of India. The analyses of the ITS and nLSU regions revealed the novelty of these species, which have been named T. pannaensis, T. subindicus, and T. xerophyticus. All three species possess pileate basidiomes, a monomitic hyphal system in the context, and the presence of cystidioles and setae. However, they differ significantly in their phylogenetic placements and other morpho-taxonomic features. Tropicoporus pannaensis is characterized by a meagrely ungulate basidiome, indistinct zones, and an obtuse margin. Tropicoporus subindicus has a triquetrous basidiome and a radially cracked, crusted pileal surface with an acute margin, while T. xerophyticus is distinguished by an imbricate, perennial basidiome with an abundantly warted pileal surface. A phylogenetic tree is provided to show the placement of the three new species, along with detailed descriptions and illustrations. Additionally, a key for the identification of the Asian species of Tropicoporus is presented. [ABSTRACT FROM AUTHOR]

A multigene phylogeny of the Inocybe alienospora group is presented based on analyses of ITS, 28S, and rpb2 nucleotide data. Four major subclades and three additional independent lineages were identified in the I. alienospora group. Two species with superficial similarities with the I. alienospora group, viz, I. multicoronata and I. elata, however, were not nested within the I. alienospora group. Inocybe sect. Leptocybe is proposed to accommodate the I. alienospora group in a more formal classification system. As such, sect. Leptocybe now includes 12 documented species and seven new species described in this work. The seven new species include I. aprica sp. nov., I. casuarinoides sp. nov. I. haikouensis sp. nov., three species associated with Casuarina from tropical China; also I. heteromorpha, a species associated with fagaceous trees from tropical China; and I. aurescens sp. nov., I. juji sp. nov., and I. peppa sp. nov., three species associated with fagaceous trees from subtropical China. In addition, new geographical data for I. carpinicola and I. acutata are reported. The East Asian species I. acutata and the neotropical species I. lasseri were confirmed as members of sect. Leptocybe. A key to the 19 species in sect. Leptocybe is also provided. [ABSTRACT FROM AUTHOR]

China has a complex and diverse forest ecological environment, which breeds abundant forest macrofungi, including some edible, medicinal, and poisonous species. During the investigations of macrofungi in the Saihanba National Nature Reserve, North China, we collected abundant specimens of Agaricales and Polyporales within the Agaricomycetes. Based on the morphological characters and molecular evidence of DNA sequences including the internal transcribed spacer (ITS) regions, the large subunit of nuclear ribosomal RNA gene (nLSU), the small subunit of mitochondrial rRNA gene (mtSSU), the small subunit of nuclear ribosomal RNA gene (nuSSU), the largest subunit of RNA polymerase II (RPB1), the second largest subunit of RNA polymerase II gene (RPB2), the β-tubulin gene (TUB), and the translation elongation factor 1-α gene (TEF1), this study identifies ten species of Agaricales and Polyporales new to science, viz. Cyanosporus subpopuli, Gelatinofungus betulina, Lycoperdon pseudoperlatum, Macrocystidia hebeiensis, Mycena subbrunnea, M. subpura, M. variispora, M. violocea-ardesiaca, Picipes griseus, and Pleuroflammula hebeiensis. Detailed morphological descriptions, fruiting bodies, and microscopic structure diagrams of these ten novel species are provided. [ABSTRACT FROM AUTHOR]

A new belondirid, dorylaimid taxon, Oleaxonchium olearum gen. et sp. nov., collected from an olive grove in the Andalusia region of Spain, is characterised, including its morphological description, morphometrics, SEM study, and molecular (18S-, 28S-rDNA) analyses. The new genus displays a unique combination of traits that distinguishes it from its closest genera: a rectangular lip region with sclerotized margins when observed in lateral view and visibly hexagonal in face view under SEM; a comparatively long cheilostom with thickened walls at its anterior part; a short isthmus-like section separating both pharyngeal regions; a mono-opistho-ovarian didelphic female genital system without pars refringens vaginae; and a short and rounded tail. The new species is characterised by its 2.44–2.87 mm long body, lip region 7–7.5 µm wide, odontostyle 10–10.5 µm long, neck 723–973 µm long, pharyngeal expansion occupying 63–72% of the total neck length, female anterior genital branch 4–6% of body length, tripartite posterior uterus 1.9–2.6 body diameters long, with a short intermediate section bearing sclerotized elements, vulva (V = 58–61) a transverse slit, caudal region 29–35 µm long (c = 74–89, c' = 0.9–1.1), and male unknown. As derived from an integrative approach combining morphological and molecular data, the new genus is close to Metaxonchium, the polyphyly of Belondiridae is confirmed, and support is provided in favour of the monophyly of Axonchiinae.

This study presents novel findings that expand our understanding of the evolutionary history and diversity of the Limoniidae subfamily Limnophilinae, with a specific focus on the relict genus Chilelimnophila. The family Limoniidae is well documented in the fossil record, with many species considered relicts in the modern fauna. Our study is based on the discovery of the first fossil specimens of Chilelimnophila in both Cretaceous Spanish and Kachin amber. The new materials have allowed the establishment of a new subgenus Chilelimnophila (Ribeironia) Krzemiński, Kania-Kłosok et Arillo, subgen. nov. and three new species: Chilelimnophila (Ribeironia) amorimi Krzemiński, Kania-Kłosok et Arillo, sp. nov. Chilelimnophila (Chilelimnophila) wangi Krzemiński, Kania-Kłosok et Arillo, sp. nov. and Chilelimnophila (Chilelimnophila) parva Krzemiński, Kania-Kłosok et Arillo, sp. nov. This research also significantly extends the stratigraphic range of the genus, providing evidence of its existence dating back to the Early Cretaceous period. The morphology and phylogenetic analysis of Chilelimnophila and related genera within the Limoniidae subfamily Limnophilinae provide valuable insights into the evolutionary relationships of these organisms. Furthermore, our research highlights the unique environmental conditions of Cretaceous Spanish and Kachin amber formations, which differ significantly from the current habitat of these organisms.

This study is intended to draw attention to the potential diversity at the species-level in the genus Hemidiscus, both fossil and Recent, to reject unsupported explanations of polymorphism for 'variable' sets of specimens, and to act as a prolegomena for its eventual re-assessment, along with its relationships within the family Hemidiscaceae. It is not intended as a revision of the genus nor is it a complete evaluation of the species-level diversity. It is a summary of some of the types found in the BM, especially those still in the genus Euodia, to provide arguments for not sinking all species currently known in Hemidiscus into Actinocyclus. Three new species are described: Hemidiscus kociolekii, Hemidiscus moronensis and Hemidiscus gigantea, the latter two are new species solely because they lack a validly published name. Four new combinations are proposed. [ABSTRACT FROM AUTHOR]

Species of Micropsalliota generally grow in the tropics and are characterised by small, slender basidiomes, brown basidiospores, and cheilocystidia that vary in shape with capitate or subcapitate apex, and pigmented pileipellis. Based on morphological characters and molecular evidence, here we describe seven new species from southern China, viz. Micropsalliota ferruginea, M. fimbriata, M. gigaspora, M. longicystis, M. nana, M. squarrosa, and M. umbonata. Micropsalliota appendiculata, a species recently described from Vietnam, was first recorded in China. The Maximum likelihood and Bayesian analyses based on multi-locus sequence datasets (the nuc rDNA internal transcribed spacer region ITS1-5.8S-ITS2, nrITS; the D1–D2 domains of nuc 28S rDNA, LSU; partial sequences of the most variable region of the second-largest subunit of RNA polymerase II, rpb2, and a portion of the translation-elongation factor 1-α, tef1) shows that the genus is separated into 11 major clades and subclades. To aid in diagnosis, a key to 32 species of Micropsalliota in China is provided. [ABSTRACT FROM AUTHOR]

Here we present new insights into Chironomidae (Insecta, Diptera) preserved in Lower Cretaceous Lebanese amber. We describe a new genus and species, Electroneura pinhoi gen. et sp. nov., seemingly related to Tanypodinae and offer an amended description of Libanopelopia cretacica Veltz, Azar and Nel, 2007. Moreover, our investigation highlights the challenges of assigning fossils to modern taxonomic groups, based on previous studies of Tanypodinae, underscoring the necessity of considering the geological context and utilizing, when possible, both morphological and molecular data from extant taxa to validate taxonomic assignments in paleontological studies.

Abstract [Objective] The study aims to identify and describe a new species Cinnamomum huarum (Lauraceae), which was collected from Nanjian, Yunnan of China. [Methods] This species was confirmed as a new taxa by morphological comparison with morphologically similar species and molecular phylogenetic study based on chloroplast genome data. [Results] The new species was similar to C. chago: Pinnately veined, leaves opposite or subopposite, long acumen, branchlets sparsely puberulent, terminal bud densely pubescent, leaf blade gray white abaxially and puberulent, margin undulate and fruit oblate. The chloroplast genome size of this species was 154 078 bp, which was 1 325 bp longer than C. chago and 1 348 bp longer than C. pittosporoides, having an extra 678 bp fragment in the inverted repeat region compared to C. chago and C. pittosporoides. In the phylogenetic tree constructed with whole chloroplast genome of 36 Lauraceae species, C. huarum formed an independent parallel branch with C. pittosporoides and other species. [Conclusion] Both the morphological and phylogenetic research indicate that C. huarum is a distinct species.

A new species of skipper butterfly from the Brazilian Atlantic Forest belonging to the subtribe Moncina (Lepidoptera: Hesperiidae: Hesperiinae: Hesperiini) is herein described: Eprius punctula Medeiros, Gualberto & O. Mielke sp. nov. The new species has a color pattern similar to other species in the genus, differing by the presence of a small yellow spot at the distal end of the discal cell on the dorsal and ventral surfaces of the forewing (absent in some specimens). The male and female genitalia are similar to those of Eprius repens (Evans, 1955), but the spined projection near the proximal-ventral margin of the harpe and the approximately straight distal margin of the lamella postvaginalis are exclusive traits of E. punctula sp. nov. Illustrations of the adults and genitalia of both sexes and the male stigma are provided.

Lichens are multi-component microbial communities where yeasts are common. This work was designed to address the taxonomic diversity and distribution of cultivated endothallic yeasts in terricolous lichens of the genus Cladonia. Lichens Cladonia stellaris, C. rangiferina, C. cornuta, and C. pleurota from arctic, subarctic, and continental boreal climates in Russia in a range of biotopes were studied. In total, 40 yeast species were isolated. It revealed a broad taxonomic range of endothallic yeast with a substantial proportion of basidiomycetes from subphyla Agaricomycotina and Pucciniomycotina. Many common yeast species were found within the epithallic and endothallic yeast communities of some lichens studied. The physiological and ecological characterization of 30 basidiomycetous endothallic yeasts enhances our understanding of lichen habitats and may aid in culturing seldom-isolated lichenicolous fungi. Out of 40 species in this study, 21 new yeast species were discovered, and 10 new yeast species were proposed with their formal descriptions. They are Colacogloea glushakovae sp. nov., Cyrenella lichenicola sp. nov., Microsporomyces wangii sp. nov., Microsporomyces cladoniae sp. nov., Genolevuria nadymea sp. nov., Teunia turchettiae sp. nov., Phaeotremella sibirica sp. nov., Phaeotremella endothallina sp. nov., Piskurozyma altaica sp. nov., and Piskurozyma cladoniicola sp. nov.

Abstract Two new Keratinophyton species, K. kautmanovae sp. nov. and K. keniense sp. nov., isolated from soil samples originating from two different geographical and environmental locations (Africa and Europe) are described and illustrated. Phylogenetically informative sequences obtained from the internal transcribed spacer (ITS) region and the nuclear large subunit (LSU) rDNA, as well as their unique phenotype, fully support novelty of these two fungi for this genus. Based on ITS and LSU combined phylogeny, both taxa are resolved in a cluster with eight accepted species, including K. alvearium, K. chongqingense, K. hubeiense, K. durum, K. lemmensii, K. siglerae, K. submersum, and K. sichuanense. The new taxon, K. kautmanovae, is characterized by clavate, smooth to coarsely verrucose conidia, absence of arthroconidia, slow growth at 25 °C, and no growth at 30 °C, while K. keniense is morphologically unique with a high diversity of conidial shapes (clavate, filiform, globose, cymbiform and rhomboid). Both species are described based on their asexual, a chrysosporium-like morph. While the majority of hitherto described Keratinophyton taxa came from Europe, India and China, the new species K. keniense represents the first reported taxonomic novelty for this genus from Africa.

Species of Micropsalliota generally grow in the tropics and are characterised by small, slender basidiomes, brown basidiospores, and cheilocystidia that vary in shape with capitate or subcapitate apex, and pigmented pileipellis.

Micropsalliota ferruginea, M. fimbriata, M. gigaspora, M. longicystis, M. nana, M. squarrosa, and M. umbonata. Micropsalliota appendiculata, a species recently described from Vietnam, was first recorded in China. The Maximum likelihood and Bayesian analyses based on multi-locus sequence datasets (the nuc rDNA internal transcribed spacer region ITS1-5.8S-ITS2, nrITS; the D1–D2 domains of nuc 28S rDNA, LSU; partial sequences of the most variable region of the second-largest subunit of RNA polymerase II, rpb2, and a portion of the translation-elongation factor 1-α, tef1) shows that the genus is separated into 11 major clades and subclades. To aid in diagnosis, a key to 32 species of Micropsalliota in China is provided.

Two new genera and species of Ithonidae, i.e. Stictopolystoechotes sparsulus Gao, Xu et Wang gen. et sp. nov. and Pycnopolystoechotes striatus Gao, Xu et Wang gen. et sp. nov., are described from the Middle Jurassic Jiulongshan Formation, Inner Mongolia, China. The two new genera can be assigned to the Polystoechotes genus-group of Ithonidae by the combination of following characters: elongated forewing, Sc and RA fused distally, crossveins in radical sector sparse except for the gradate series, and simple CuP branches. The known wing markings among the Jurassic Polystoechotes genus-group were outlined, which suggested the diversification of wing markings was possibly positively associated with the species radiation of this lineage during this period. Moreover, a key to fossil genera of the Polystoechotes genus-group was provided.

Sanguinoderma (Ganodermataceae) is recognized as a valuable medicinal resource in Taiwan, China. Additionally, it serves as a traditional folk medicine for treating neurotic epilepsy in Malaysia. This study involved the collection of six specimens of Sanguinoderma from Yunnan Province, China. Employing multigene phylogenetic analysis of DNA sequences, including internal transcribed spacer (ITS), nuclear large subunit (LSU), RNA polymerase II second largest subunit (rpb2), translation elongation factor 1-alpha (tef1-α), mitochondrial small subunit (mtSSU), nuclear small subunit (nSSU) and morphological examinations, three new species, viz. Sanguinoderma concentricum, S. dehongense and S. ovisporum, are introduced. Sanguinoderma concentricum is characterized by a central stipe basidiomata, an orbicular to suborbicular pileus, a grayish-yellow surface with alternating concentric zones and wavy margin-like petals and regular pileipellis cells (4–8 × 17–28 μm). Sanguinoderma dehongense is characterized by a long stipe and flabelliform basidiomata, a dark-grayish yellow-to-dark-yellow pileus surface, irregular pileipellis cells and wavy margin and ellipsoid basidia (8–11 × 9–13 μm). Sanguinoderma ovisporum is characterized by a reniform basidiomata, a heterogeneous context and ovoid basidiospores (7.5–8.6 × 5.5–7.2 µm). A detailed description and illustrations of these new species are provided, as well as a morphological comparison with similar taxa. [ABSTRACT FROM AUTHOR]

Field work focused on the Kuedinskie Kluchiki locality, Perm region, Urals, Russia, which contains a rich assemblage of diverse fossil organisms including higher plants (equisetophytes, pteridosperms, ginkgophytes, conifers, vojnovskyans) represented by stems, leaves and reproductive organs; invertebrates (mollusks, arthropods), and tetrapods (temnospondyl amphibians, seymouriamorphs, cotylosaurs, synapsids, diapsids), as well as bony fishes. General characteristics of the taxonomical composition of the Kuedinskie Kluchiki locality are given. A new peltaspermalean pteridosperm taxon, Compsopteris longipinnata sp. nov., and a voltzialean conifer Archaeovoltzia kuedensis sp. nov. are described. General considerations on the paleoecologic and paleogeographic conditions of the Kuedinskie Kluchiki locality origin are given. [ABSTRACT FROM AUTHOR]

Two new Keratinophyton species, K. kautmanovae sp. nov. and K. keniense sp. nov., isolated from soil samples originating from two different geographical and environmental locations (Africa and Europe) are described and illustrated. Phylogenetically informative sequences obtained from the internal transcribed spacer (ITS) region and the nuclear large subunit (LSU) rDNA, as well as their unique phenotype, fully support novelty of these two fungi for this genus. Based on ITS and LSU combined phylogeny, both taxa are resolved in a cluster with eight accepted species, including K. alvearium, K. chongqingense, K. hubeiense, K. durum, K. lemmensii, K. siglerae, K. submersum, and K. sichuanense. The new taxon, K. kautmanovae, is characterized by clavate, smooth to coarsely verrucose conidia, absence of arthroconidia, slow growth at 25 °C, and no growth at 30 °C, while K. keniense is morphologically unique with a high diversity of conidial shapes (clavate, filiform, globose, cymbiform and rhomboid). Both species are described based on their asexual, a chrysosporium-like morph. While the majority of hitherto described Keratinophyton taxa came from Europe, India and China, the new species K. keniense represents the first reported taxonomic novelty for this genus from Africa.

A new genus and species of ponerine ant from Mexican amber, Siinikaponera sulimata, is described and illustrated. The type material is an amber inclusion from the Montecristo mine in Chiapas, Mexico, which dates back to the Oligo-Miocene period. Siinikaponera sulimata gen. et sp. nov. shares traits with other ants in the subfamily Ponerinae, including the outer edges of the frontal lobes forming simple short semicircles or blunt triangles, presence of promesonotal suture, meso- and metatibia with 0–2 spurs, antenna with 12 segments, constriction between the first and second gastral tergite well impressed, presence of sting, complete wing venation, and complete cell patterns. Siinikaponera sulimata gen. et sp. nov. also has unique features that separate it from other ponerine ants, such as fore, middle and hind tibiae with two spurs each, anterior margin of clypeus with two anteriorly projecting lobes, mandible dentition pattern, posterior peduncle of petiole long, and presence of relatively long coxae. A distinctive feature of Siinikaponera sulimata gen. et sp. nov. is the presence of two projecting lobes on the anterior clypeal margin, a plesiomorphic character shared with the genus Dinoponera. Accordingly, this new fossil record offers valuable insights into the worldwide diversity and distribution of ponerine ants. [ABSTRACT FROM AUTHOR]

Two new Cortinarius species in subgenus Leprocybe, Cortinarius hengduanensis and C. yadingensis, are proposed based on a combination of morphological and molecular evidence. Cortinarius hengduanensis has distinct olive tinged basidiomata, a squamulose pileus, and small, subglobose to broadly ellipsoid basidiospores, the ITS sequence differs from that of C. flavifolium by at least 28 substitutions and independent positions. Cortinarius yadingensis has a squamulose pileus and subglobose to broadly ellipsoid coarsely verrucose basidiospores, the ITS sequence has at least 11 substitutions and index position deviations from the other members of the Leprocybe section. Both new species were found in mixed forests of southwest China. [ABSTRACT FROM AUTHOR]

The genera Cephalotrichum and Microascus contain ecologically, morphologically and lifestyle diverse fungi in Microascaceae (Microascales, Sordariomycetes) with a world-wide distribution. Despite previous studies having elucidated that Cephalotrichum and Microascus are highly polyphyletic, the DNA phylogeny of many traditionally morphology-defined species is still poorly resolved, and a comprehensive taxonomic overview of the two genera is lacking. To resolve this issue, we integrate broad taxon sampling strategies and the most comprehensive multi-gene (ITS, LSU, tef1 and tub2) datasets to date, with fossil calibrations to address the phylogenetic relationships and divergence times among major lineages of Microascaceae. Two previously recognised main clades, Cephalotrichum (24 species) and Microascus (49 species), were re-affirmed based on our phylogenetic analyses, as well as the phylogenetic position of 15 genera within Microascaceae. In this study, we provide an up-to-date overview on the taxonomy and phylogeny of species belonging to Cephalotrichum and Microascus, as well as detailed descriptions and illustrations of 21 species of which eight are newly described. Furthermore, the divergence time estimates indicate that the crown age of Microascaceae was around 210.37 Mya (95 % HPD: 177.18–246.96 Mya) in the Late Triassic, and that Cephalotrichum and Microascus began to diversify approximately 27.07 Mya (95 % HPD: 20.47–34.37 Mya) and 70.46 Mya (95 % HPD: 56.96–86.24 Mya), respectively. Our results also demonstrate that multigene sequence data coupled with broad taxon sampling can help elucidate previously unresolved clade relationships. [ABSTRACT FROM AUTHOR]

The genus Peronospora is the largest genus of the oomycetes, fungus-like members of the kingdom Straminipila that also contains amoeboid (e.g., Leukarachnion) and plant-like (e.g., Laminaria) lifeforms. Peronospora species are obligate biotrophic plant pathogens, causing high economic losses in various crops and ornamentals, including Plantago species. Several species of Plantago are used as speciality crops and medicinal plants. In this study, Peronospora species parasitic on Plantago were investigated based on morphology and phylogenetic analyses using two nuclear (ITS, nrLSU) loci and one mitochondrial (cox2) locus. As a result of these investigations, 10 new species are added to the already known Peronospora species on Plantago. Interestingly, it was found that four independent species are parasitic to Plantago major, highlighting that the reliance on the host plant for pathogen determination can be misleading in Peronospora. Taking this into account, morphological and phylogenetic analyses should be conducted as a prerequisite for effective quarantine regulations and phytosanitary measures. [ABSTRACT FROM AUTHOR]

Oceanic islands have been recognized as natural laboratories in which to study a great variety of evolutionary processes. One such process is evolutionary radiations, the diversification of a single ancestor into a number of species that inhabit different environments and differ in the traits that allow them to exploit those environments. The factors that drive evolutionary radiations have been studied for decades in charismatic organisms such as birds or lizards, but are lacking in lichen-forming fungi, despite recent reports of some lineages showing diversification patterns congruent with radiation. Here we propose the Ramalina decipiens group as a model system in which to carry out such studies. This group is currently thought to be comprised of five saxicolous species, all of them endemic to the Macaronesian region (the Azores, Madeira, Selvagens, Canary and Cape Verde islands). Three species are single-island endemics (a rare geographic distribution pattern in lichens), whereas two are widespread and show extreme morphological variation. The latter are suspected to harbor unrecognized species-level lineages. In order to use the Ramalina decipiens group as a model system it is necessary to resolve the group's phylogeny and to clarify its species boundaries. In this study we attempt to do so following an integrative taxonomy approach. We constructed a phylogenetic tree based on six molecular markers, four of which are newly developed and generated competing species hypotheses based on molecular (species discovery strategies based on both single locus and multilocus datasets) and phenotypic data (unsupervised clustering algorithms based on morphology, secondary chemistry and geographic origin). We found that taxonomic diversity in the Ramalina decipiens group has been highly underestimated in previous studies. In consequence, we describe six new species, most of them single-island endemics and provide a key to the group. Phylogenetic relationships among species have been reconstructed with almost full support which, coupled with the endemic character of the group, makes it an excellent system for the study of island radiations in lichen-forming fungi.

Candida is a polyphyletic genus of asexually reproducing yeasts in the Saccharomycotina with more than 400 species that occur in almost all families of the subclass and its name is strongly connected with the infectious disease candidiasis. During the last two decades, approximately half of the Candida species have been reassigned into more than 36 already existing genera and 14 newly proposed genera, but the polyphyletic feature of the genus largely remained. Candida auris is an important, globally emerging opportunistic pathogen that has caused life-threatening outbreaks in healthcare facilities worldwide. This species belongs to the Candida auris-Candida haemuli (CAH) clade in the Metschnikowiaceae, a clade that contains multidrug-resistant clinically relevant species, but also species isolated from natural environments. The clade is phylogenetically positioned remotely from the type species of the genus Candida that is Candida vulgaris (currently interpreted as a synonym of Candida tropicalis) and belongs to the family Debaryomycetaceae. Although previous phylogenetic and phylogenomic studies confirmed the position of C. auris in the Metschnikowiaceae, these analyses failed to resolve the position of the CAH clade within the family and its delimitation from the genera Clavispora and Metschnikowia. To resolve the position of the CAH clade, phylogenomic and comparative genomics analyses were carried out to address the phylogenetic position of C. auris and related species in the Metschnikowiaceae using several metrics, such as the average amino acid identity (AAI) values, the percentage of conserved proteins (POCP) and the presence-absence patterns of orthologs (PAPO). Based on those approaches, 13 new genera are proposed for various Candida and Hyphopichia species, including members of the CAH clade in the Metschnikowiaceae. As a result, C. auris and related species are reassigned to the genus Candidozyma. Fifty-five new combinations and nine new species are introduced and this will reduce the polyphyly of the genus Candida. [ABSTRACT FROM AUTHOR]

Acorrect classification of fungi, including yeasts, is of prime importance to understand fungal biodiversity and to communicate about this diversity. Fungal genera are mainly defined based on phenotypic characteristics and the results of single or multigene-based phylogenetic analyses. However, because yeasts often have less phenotypic characters, their classification experienced a strong move towards DNA-based data, from short riboso)mal sequences to multigene phylogenies and more recently to phylogenomics. Here, we explore the usefulness of various genomics-based parameters to circumscribe fungal genera more correctly taking the yeast domain as an example. Therefore, we compared the results of a phylogenomic analysis, average amino acid identity (AAI) values, the presence of conserved signature indels (CSIs), the percentage of conserved proteins (POCP) and the presence-absence patterns of orthologs (PAPO). These genome-based metrics were used to investigate their usefulness in demarcating 13 hitherto relatively well accepted genera in Saccharomycetaceae, namely Eremothecium, Grigorovia, Kazachstania, Kluyveromyces, Lachancea, Nakaseomyces, Naumovozyma, Saccharomyces, Tetrapisispora, Torulaspora, Vanderwaltozyma, Zygosaccharomyces and Zygotorulaspora. As a result, most of these genera are supported by the genomics-based metrics, but the genera Kazachstania, Nakaseomyces and Tetrapisispora were shown to be genetically highly diverse based on the above listed analyses. Considering the results obtained for the presently recognized genera, a range of 80–92 % POCP values and a range of 60–70 % AAI values might be valuable thresholds to discriminate genera in Saccharomycetaceae. Furthermore, the genus-specific genes identified in the PAPO analysis and the CSIs were found to be useful as synapomorphies to characterize and define genera in Saccharomycetaceae. Our results indicate that the combined monophyly-based phylogenomic analysis together with genomic relatedness indices and synapomorphies provide promising approaches to delineating yeast genera and likely those of filamentous fungi as well. The genera Kazachstania, Nakaseomyces and Tetrapisispora are revised and we propose eight new genera and 41 new combinations. [ABSTRACT FROM AUTHOR]

This study aims to report three new species of Conoideocrella and Moelleriella from Yunnan Province, Southwestern China. Species of Conoideocrella and Moelleriella parasitize scale insects (Coccidae and Lecaniidae, Hemiptera) and whiteflies (Aleyrodidae, Hemiptera). Based on the phylogenetic analyses of the three-gene nrLSU, tef-1α, and rpb1, it showed one new record species (Conoideocrella tenuis) and one new species (Conoideocrella fenshuilingensis sp. nov.) in the genus Conoideocrella, and two new species, i.e., Moelleriella longzhuensis sp. nov. and Moelleriella jinuoana sp. nov. in the genus Moelleriella. The three new species were each clustered into separate clades that distinguished themselves from one another. All of them were distinguishable from their allied species based on their morphology. Morphological descriptions, illustrations, and comparisons of the allied taxa of the four species are provided in the present paper. In addition, calculations of intraspecific and interspecific genetic distances were performed for Moelleriella and Conoideocrella. [ABSTRACT FROM AUTHOR]

Alpinia oxyphylla is a traditional Chinese medicinal plant with a medicinal history of more than 1700 years. Ring leaf blight (RLB) disease, caused by pestalotioid species, is an important disease of A. oxyphylla, seriously affecting the yield and quality of its fruits. The causal agent of RLB disease has not been systematically identified or characterized yet. In this study, thirty-six pestalotioid strains were isolated from the leaves and stems of A. oxyphylla that was collected from six cities of Hainan province, China. Based on the multi-locus phylogeny (ITS, tef-1α and tub2) and morphological characteristic analyses, seventeen species belonging to three genera (Neopestalotiopsis, Pestalotiopsis and Pseudopestalotiopsis) were identified, and six new species (N. baotingensis, N. oblatespora, N. olivaceous, N. oxyphylla, N. wuzhishanensis and N. yongxunensis) were described. Pathogenicity tests revealed that strains of Neopestalotiopsis species caused more severe ring leaf blight on A. oxyphylla than strains of Pestalotiopsis and Pseudopestalotiopsis under wounded inoculation conditions.

Fusarium agapanthi is newly reported from the centre of origin of Agapanthus in South Africa, where it is associated with dead flower stalks of Agapanthus praecox. Mjuua agapanthi, a rare hyphomycete with a morphology corresponding to asexual morphs of Pyxidiophora, was isolated as mycoparasitic on F. agapanthi, along with bacteria that co-occurred in synnematal heads of M. agapanthi. Germinating conidia of M. agapanthi were observed to parasitise germinating conidia of F. agapanthi. Although M. agapanthi could not be cultivated on its own, the association with Fusarium proved to not be restricted to F. agapanthi, as it could also be cultivated with other Fusarium spp. Mjuua agapanthi is a member of Pyxidiophorales, an order of obligate insect parasitic microfungi. The exact role of the bacteria in synnematal heads of M. agapanthi remains to be further elucidated, although one bacterium, Alsobacter metallidurans, appeared to cause lysis of the synnematal conidial cell walls. This discovery suggests that many unculturable obligate biotrophic microbes can probably be cultivated if co-cultivated with their respective hosts. [ABSTRACT FROM AUTHOR]

The smut fungal genus Anthracoidea contains more than 100 species that parasitize hosts predominantly in the sedge genus Carex. Anthracoidea species are mainly found in the boreal zones of the Northern Hemisphere and many species have an arctic-alpine distribution. Recent re-organization of the taxonomy of the main host genus Carex questions current understanding of host associations in Anthracoidea. Host specificity for many of the species in this genus is considered to be quite broad and a host spectrum of over 10 host species is common. One aim of the study is to understand the potential influence that host taxonomy has on the evolutionary patterns of Anthracoidea. Additionally, by including more specimens, we clarify host specificity and species delimitation in Anthracoidea sempervirentis, a prevalent species occurring on different host species in different Carex subgroups using molecular data. Host colonization patterns within Anthracoidea are complex, and different subclades of Carex have been colonized several times independently, whereas clades of related Anthracoidea species often occur on Carex species from the same host clade. Parasites previously thought to be Anthracoidea sempervirentis occurring on the different Carex host are shown to be at least four distinct species that are restricted to individual host species. Three new species, Anthracoidea ferrugineae on Carex ferruginea from the Alps and the Carpathians, A. firmae on Carex firma from the Alps, and A. kitaibelianae on Carex kitaibeliana from mountains in the Balkan Peninsula, are described and illustrated. An emended description of Anthracoidea sempervirentis is also provided. Anthracoidea sempervirentis in its emended circumscription consists of two clades that correspond to respective clades within Carex sempervirens. The study shows that host colonization in Anthracoidea is more complex than current host taxonomy suggests. Further, including several specimens per host species results in a much higher diversity within Anthracoidea than previously assumed. [ABSTRACT FROM AUTHOR]

Species of Pseudocercospora are commonly associated with leaf and fruit spots on diverse plant hosts in sub-tropical and tropical regions. Pseudocercospora spp. have mycosphaerella-like sexual morphs, but represent a distinct genus in Mycosphaerellaceae (Mycosphaerellales, Dothideomycetes). The present study adds a further 29 novel species of Pseudocercospora from 413 host species representing 297 host genera occurring in 60 countries and designates four epitypes and one lectotype for established names. This study recognises 329 species names, with an additional 69 phylogenetic lineages remaining unnamed due to difficulty in being able to unambiguously apply existing names to those lineages. To help elucidate the taxonomy of these species, a phylogenetic tree was generated from multi-locus DNA sequence data of the internal transcribed spacers and intervening 5.8S nuclear nrRNA gene (ITS), partial actin (actA), and partial translation elongation factor 1-alpha (tef1), as well as the partial DNA-directed RNA polymerase II second largest subunit (rpb2) gene sequences.

Epitypes are designated for Cercospora bonjeaneae-rectae, Cercospora halleriae, Ps. eucleae, and an epitype as well as a lectotype for Ps. macadamiae. Results obtained in the present study contribute to a better understanding of the host specificity and distribution in Pseudocercospora spp., many of which represent important pathogens of food or fibre crops, or organisms of quarantine concern.

During a survey of culturable microfungi from the bark of sugar maple (Acer saccharum), Atrocalyx glutinosus and Nigrograna rubescens, two novel species of Pleosporales (Dothideomycetes) were isolated from several locations in eastern Ontario, Canada. Formal species descriptions are presented based on unique colony phenotypes and micromorphological characteristics and supported using multi-locus molecular phylogenetic comparisons with similar species. Both A. glutinosus and N. rubescens produce pycnidial asexual morphs in culture. As their names imply, under specific culture conditions, A. glutinosus excretes large amounts of the glutinous polysaccharide pullulan and N. rubescens produces a dark red naphthoquinone pigment that diffuses in the culture medium.

Based on newly acquired inclusions in Taimyr amber, we have described new taxa (Sidorchukaphis katyae Ogłaza & Wegierek gen. et sp. nov.; Baikuraphis abdominalis gen. et sp. nov.; Canadaphis ugolyaki Ogłaza & Wegierek sp. nov.) of aphids or redescribed previously reported forms (Ambaraphis baikurensisPalaeoaphis incognita Tajmyraphis zherichini; Retinaphis glandulosa). The presented species belong to both extinct and extant families from the Late Cretaceous stage of aphid evolution. A cladistic analysis of the morphological characters of the Tajmyraphidoidea has been performed. We assign Burmitaphididae, as the subfamily Burmitaphidinae, to the Tajmyraphididae, which now comprises the subfamilies Tajmyraphidinae and Burmitaphidinae. We also suggest elevating the Mongolaphidinae to family rank (Mongolaphididae). [ABSTRACT FROM AUTHOR]

The genus Heteropsectropus Kaszab, 1941 (Tenebrionidae: Blaptinae: Platynotini) is revised to include the following three species: H. aenescens Kaszab, 1941 (type species); H. difficilis Koch, 1954; H. longantennatus Koch, 1954. Four synonymies are proposed: H. difficilis (= H. amaroides Koch, 1954 syn. nov., = H. natalensis Koch, 1954 syn. nov., = H. transvaalensis Koch, 1954 syn. nov.) and H. longantennatus Koch, 1954 (= H. montisdraconis Koch, 1954 syn. nov.). A new genus, Muelleropsectropusgen. nov., is introduced to accommodate Schyzoschelus malaisei Koch, 1954. Additionally, the following synonomies are introduced within Schyzoschelus Koch, 1954: Schyzoschelus dumosicola (= Schyzoschelus dumosicola var. diversipenis Koch, 1954 syn. nov.) and Schyzoschelus simplicipes (= Schyzoschelus simplicipes willowmorensis Koch, 1954 syn. nov.). Diagnostic features and relations between the genera of the Schyzoschelus generic group are discussed and an identification key to the genera and the species of Heteropsectropus is provided. Ovovivipary is reported for H. difficilis and represents the 15th known case of this mode of reproduction for darkling beetles. The first description of pupal morphology for the subtribe Eurynotina is provided as well as that of the first- and later instar larvae. [ABSTRACT FROM AUTHOR]

The order Agaricales was divided into eight suborders. However, the phylogenetic relationships among some suborders are largely unresolved, and the phylogenetic positions and delimitations of some taxa, such as Sarcomyxaceae and Tricholomopsis, remain unsettled. In this study, sequence data of 38 genomes were generated through genome skimming on an Illumina sequencing system. To anchor the systematic position of Sarcomyxaceae and Tricholomopsis, a phylogenetic analysis based on 555 single-copy orthologous genes from the aforementioned genomes and 126 publicly accessible genomes was performed. The results fully supported the clustering of Tricholomopsis with Phyllotopsis and Pleurocybella within Phyllotopsidaceae, which formed a divergent monophyletic major lineage together with Pterulaceae, Radulomycetaceae, and Macrotyphula in Agaricales. The analysis also revealed that Sarcomyxaceae formed a unique major clade. Therefore, two new suborders, Phyllotopsidineae and Sarcomyxineae, are proposed for the two major lineages. Analyses of 450 single-copy orthologous genes and four loci suggested that Tricholomopsis consisted of at least four clades. Tricholomopsis is subsequently subdivided into four distinct sections. Seventeen Tricholomopsis species in China, including six new species, are reported. Conoloma is established to accommodate T. mucronata. The substrate preference of Tricholomopsis species and the transitions of the pileate ornamentations among the species within the genus are discussed. [ABSTRACT FROM AUTHOR]
