During lichenicolous fungal studies in India, lichen genus Ochrolechia was found infected with a black lirellate fungus. Critical microscopical examination of the fungus revealed that it is a new species of Labrocarpon, which differs from L. canariense in having narrow exciple (15.0–20.0 µm vs 20.0–50.0 µm thick), 4-spored asci, 1-septate to submuriform, constricted ascospores with larger l/w value [(2.5–)2.9–3.4–3.9(–4.5) vs (1.9–)2.1–2.5(–2.8)], habitat preference (corticolous vs saxicolous) and host selection (Ochrolechia vs Pertusaria). The new species Labrocarpon submuriforme is described in detail. [ABSTRACT FROM AUTHOR]

Sphinctrina pertusa Falswal A. is described as a new species of lichenicolous fungus from India. It is characterised by eight non-septate, broadly ellipsoidal, uniseriate, ascospores with olive green tint and irregular ridge like ornamentations. This fungus is growing on known lichen host Pertusaria but differs from five closely related species i.e., S. anglica, S. leucopoda, S. tubaeformis, S. turbinata, S. paramerae with different taxonomic characters. A detailed comparative analysis with non-septate closely related species is provided. [ABSTRACT FROM AUTHOR]

The crustose lichen genus Pertusaria comprises over ca. 800 species worldwide. In total, 20 Pertusaria species were localized to the Mt. Sorak and Jeju-do in Korea. To date, information regarding the distribution of Pertusaria species in the South Korean peninsula is scarce. In this study, we collected Pertusaria species across South Korea and identified them based on morphological, chemical, and molecular characteristics. Of the 387 samples collected, we identified 24 taxa and 1 variety, of which 17 were previously recorded, and 6 taxa were newly found in South Korea (P. leioplaca, P. leucosora var. violascens, P. texana, P. thiospoda, P. thwaitesii, and P. xanthodes), 2 known species were transferred to Varicellaria (Varicellaria lactea and V. velata), one species was transferred to Variolaria as a new record (Variolaria multipunctoides) and one was a new species (P. jogyeensis J. S. Park & J.-S. Hur, sp. nov.). Characteristics of the newly discovered species, P. jogyeensis, are as follows: smooth to bumpy thallus, scattered to crowded poriform apothecia, blackish ostioles, definitely sunken, thin yellowish green rims around ostioles, 8-spored ascus, and the presence of perlatolic acid and thiophaninic acid (chlorinated xanthone). Phylogenetic studies on P. jogyeensis based on the mitochondrial small subunit sequence revealed proximity to P. flavicans and P. texana, and supported its classification as a new species within the genus Pertusaria. Additionally, we describe the chemical composition and morphology of all listed species in detail and provide an artificial key for identification. [ABSTRACT FROM AUTHOR]

Hansen E. S., 2013: Notes on some new and interesting Greenland lichens with particular emphasis on high arctic taxa [Pastabos apie retas ir įdomias Grenlandijos kerpes, ypač poliarinių dykumų taksonus]. - Bot.

The lichen-forming genus Pertusaria under its current circumscription is polyphyletic and its phylogenetic ailiations are uncertain. Here we study the species of the genera Pertusaria and Varicellaria which contain lecanoric acid as major constituent, have disciform apothecia, strongly amyloid asci, non-amyloid hymenial gel, 1-2-spored asci, and 1- or 2-celled ascospores with thick, 1-layered walls. We infer phylogenetic relationships using maximum likelihood and Bayesian analyses based on four molecular loci (mtSSU, nuLSU rDNA, and the protein-coding, nuclear RPB1 and MCM7 genes). Our results show that the lecanoric acid-containing species form a well-supported, monophyletic group, which is only distantly related to Pertusaria s.str. he phylogenetic position of this clade is unclear, but placement in Pertusaria s.str. is rejected using alternative hypothesis testing. he circumscription of the genus Varicellaria is enlarged to also include species with non-septate ascospores. Seven species are accepted in the genus: Varicellaria culbersonii (Vezda) Schmitt & Lumbsch, comb. nov., V. hemisphaerica (Flörke) Schmitt & Lumbsch, comb. nov., V. kasandjeii (Szatala) Schmitt & Lumbsch, comb. nov., V. lactea (L.) Schmitt & Lumbsch, comb. nov., V. philippina (Vain.) Schmitt & Lumbsch, comb. nov., V. rhodocarpa (Körb.) h. Fr., and V. velata (Turner) Schmitt & Lumbsch, comb. nov. A key to the species of Varicellaria is provided. [ABSTRACT FROM AUTHOR]

Based on field trips between 1995-2007, rare and noteworthy lichens from the Altai Mountains in southern Siberia are described. Bacidia zerovii Oxner is recognized as a synonym of Scoliciosporum chiorococcum (Graewe ex Stenh.) Vézda. Lecidea brenneri H. Magn. is lectotypified and synonymized with Lecania cyrtellina (Nyl.) Sandst. The new combination Puttea exsequens (Nyl.) Prmtzen & Davydov is introduced for Lecidea exsequens Nyl. and is the oldest validly published name for Lecidea gibberosa sensu Th. Fr. non Ach. Of the 33 species reported here, five species Lecania croatica, Lecanora pseudosarcopidoides, Lecidea, L. sanguineoatra, Puttea exsequens and Rim ularia fuscosora are new for Asia and Russia, Buellia arborea is new to Asia, Lecanorafarinaria is new to Russia, Caloplaca herbidella, C. sorocarpa, Felihanera subtilis, Lecidea pullata, and Pertusaria coccodes are new to Siberia. Several species are reported as new to West or South Siberia. Most corticolous lichen species display a more or less circumboreal distribution and also occur in Europe and North America.

This paper presents a study on a chemical variation of Pertusaria flavida in Poland. Six chemotypes were determined in the studied material, of which chemotypes IV, V and VI were never reported before. All of them produce thiophaninic acid as the diagnostic metabolite for the species and this is the only major substance in chemotype I. Chemotype II contains in addition also 2'-O-methylperlatolic acid (± confluentic acid), whereas chemotype III stictic acid complex (± minor or trace amounts of norstictic acid). Chemotype IV is characterized by the presence of 2'-O-methylperlatolic acid and stictic acid complex (± norstictic acid in minor to trace amounts). Chemotype V produce norstictic acid as a major additional substance and chemotype VI contains 2'-O-methylperlatolic acid together with norstictic acid. Chemotype II was the most common chemotype (c.75 % of specimens) in studied material. Distribution maps are presented for all chemotypes. [ABSTRACT FROM AUTHOR]

Abstract: A focused and rapid microwave-assisted extraction (MAE) process was carried out and optimized for secondary metabolites from crustose lichens using Taguchi experimental design and quantitative analysis on TLC by a Camag® spectrophotodensitometer. The procedure was improved by quantitative determination of norstictic acid (NA), a common depsidone isolated from Pertusaria pseudocorallina (Sw.) Arn. Various experimental parameters that can potentially affect the NA extraction yields including extraction time, irradiation power, volume and the percentage of tetrahydrofuran (THF) were optimized. Results suggest that THF percentage and solvent volume were statistically the most significant factors. The optimal conditions were determined as follows: THF level of 100%, solvent volume of 15mL, microwave power of 100W and extraction time of 7min. Compared to the reflux method, MAE showed a drastic reduction of extraction time (7min vs. 3h) and solvent consumption (15mL vs. 30mL). The NA in total yield was 90% using the two methods. The optimal conditions were applied to other crustose lichens, Aspicilia radiosa, Diploicia canescens and Ochrolechia parella for the extraction of NA, diploicine (DP) and variolaric acid (VA), with 83%, 90% and 95% of recovery, respectively.

The new species Miriquidica effigurata, M. squamulosa and Pertusaria stellata are described from the southern subpolar region from collections made by Henry Imshaug and co-workers in the early 1970s. All three species occur on Campbell Island, New Zealand, with M. effigurata and P. stellata also occurring on the Auckland Islands, New Zealand, and P. stellata also being reported from Isla Desolación in southern Chile. Miriquidica effigurata and M. squamulosa are similar to M. complanata but have apothecia with a dark (K+ purple-red) lower hypothecium and thalli containing confluentic acid and norstictic acid respectively. Pertusaria stellata is similar to P. macloviana, but has shorter ascospores and a smoother, generally paler thallus lacking papillate isidia. Cephalodia are reported for the first time in both Miriquidica and Pertusaria. [ABSTRACT FROM AUTHOR]

A phylogenetic study using large subunit ribosomal DNA sequence data of several species of Siphula, representing all phenotypically recognized species groups, suggests that Siphula is not monophyletic. One lineage, including the core group related to S. ceratites and the S. decumbens group, is placed with members of the Icmadophilaceae, whereas a second distinct lineage, comprising S. complanata, S. fragilis and their relatives, has evolved within the Goccotrernataceae. To accomomodate these species, the new genus Parasiphula is described as new to science. Parasiphula consists of species restricted to cool to cold latitudes of the Southern Hemisphere. The results show a remarkable case of parallel evolution of lineages that have lost sexual stages and propagate via thallus fragments. [ABSTRACT FROM AUTHOR]

Eight species of the lichen genus Pertusaria (Pertusariaceae) are reported from the Juan Fernandez Archipelago (Chile). Pertusaria fernandeziana is described as a new species and two species, Pertusaria phlyctaenula Nyl. and Pertusaria dehiscens Müll. Arg., are recorded for the first time from the archipelago. Range extensions of the known distribution within the archipelago are reported for Pertusaria hadrocarpa Zahlbr., Pertusaria melanospora Nyl., Pertusaria pachythallina (Räsänen) Messuti, Pertusaria papillulata Nyl., and Pertusaria velata (Turner) Nyl. Pertusaria polycarpa Kremp. vat. monospora Zahlbr. is reduced to synonymy with Pertusaria papillulata and Pertusaria chilena Zahlbr. is synonymized with Pertusaria velata. A diagnostic key, descriptions, and illustrations of the species are presented with data on their habitat ecology and distribution. [ABSTRACT FROM AUTHOR]

The Opegrapha species with 3-septate ascospores growing on Pertusaria and Ochrolechia are revised. Two species are recognized: Opegrapha anomea (of which O. pertusariae, O. quaternella, O. wetmorei and possibly Leciographa weissii are considered to be synonyms), and O. blakii Ertz & Diederich sp. nov. described from a sterile lichen with an Ochrolechia-like thallus, known from Ecuador and Venezuela. Opegrapha anomea and several related lichenicolous species with roundish or irregular, often multilocular ascomata are morphologically intermediate between Opegrapha and Plectocarpon, and might represent a distinct genus. © 2004 The Linnean Society of London, Botanical Journal of the Linnean Society, 2004, 144, 235−241.

The article focuses on the proposed conservation of the name Lichen hagenii with a conserved type lichenized Ascomycota in pant classification. It in inferred that the epithet hagenii has often been applied to a common and widespread lichenized fungus in Fennoscandia, Central Europe, and eastern North America under the name Lecanora hagenii since it was introduced. However, Lichen hagenii was based on Lichen caerulescens, which was assumed as Pertusaria species in the Pertusaria hymenea group.
