Molecular phylogenetic analyses have addressed the systematic position of several major Northern Hemisphere lineages of Pezizales but the taxa of the Southern Hemisphere remain understudied. This study focuses on the molecular systematics and taxonomy of Southern Hemisphere species currently treated in the genera Underwoodia and Gymnohydnotrya. Species in these genera have been identified as the monophyletic/gymnohydnotrya lineage, but no further research has been conducted to determine the evolutionary origin of this lineage or its relationship with other Pezizales lineages. Here, we present a phylogenetic study of fungal species previously described in Underwoodia and Gymnohydnotrya, with sampling of all but one described species. We revise the taxonomy of this lineage and describe three new species from the Patagonian region of South America. Our results show that none of these Southern Hemisphere species are closely related to Underwoodia columnaris, the type species of the genus Underwoodia. Accordingly, we recognize the genus Geomorium described by Spegazzini in 1922 for G. fuegianum. We propose the new family, Geomoriaceae fam. nov., to accommodate this phylogenetically and morphologically unique Southern Hemisphere lineage. Molecular dating estimated that Geomoriaceae started to diverge from its sister clade Tuberaceae c. 112 MYA, with a crown age for the family in the late Cretaceous (c. 67 MYA). This scenario fits well with a Gondwanan origin of the family before the split of Australia and South America from Antarctica during the Paleocene-Eocene boundary (c. 50 MYA). [ABSTRACT FROM AUTHOR]

The consumption of fungi by animals is a significant trophic interaction in most terrestrial ecosystems, yet the role mammals play in these associations has been incompletely studied. In this review, we compile 1 154 references published over the last 146 years and provide the first comprehensive global review of mammal species known to eat fungi (508 species in 15 orders). We review experimental studies that found viable fungal inoculum in the scats of at least 40 mammal species, including spores from at least 58 mycorrhizal fungal species that remained viable after ingestion by mammals. We provide a summary of mammal behaviours relating to the consumption of fungi, the nutritional importance of fungi for mammals, and the role of mammals in fungal spore dispersal. We also provide evidence to suggest that the morphological evolution of sequestrate fungal sporocarps (fruiting bodies) has likely been driven in part by the dispersal advantages provided by mammals. Finally, we demonstrate how these interconnected associations are widespread globally and have far-reaching ecological implications for mammals, fungi and associated plants in most terrestrial ecosystems.

Balsamia , a hypogeous, sequestrate genus in the Helvellaceae , has been characterized variously as having three to eight species in North America, and these have been considered either different from or conspecific with European species. No available modern systematic treatment of Balsamia exists to allow for accurate identification at the species level. We sequenced DNA from recent western North American Balsamia collections, assessed relationships by sequence similarity, and identified molecular taxonomic units. From these data, we determined which matched descriptions and types of named species. ITS sequences supported 12 Balsamia species in western North America, five originally described by Harkness and Fischer and seven new species that we describe here. No sequences from Balsamia collections in western North America were nested among those of European species. We found no clear evidence for separation of Balsamia into multiple genera., (© 2018 Westerdijk Fungal Biodiversity Institute.)

Two corrections are needed to our revision of sequestrate Russula nomenclature (Elliott & Trappe 2018). Decisions are based on the International Code of Nomenclature for algae, fungi, and plants (Turland et al . 2018), hereafter referred to as the " Shenzhen Cod e". We present them in the same format as the original publication to facilitate comparison of the corrections with the previous publication., (© 2018 Westerdijk Fungal Biodiversity Institute.)

We describe three new species of Elaphomyces from eastern North America. Of the three, Elaphomyces loebiae is the rarest, known only from North Carolina and South Carolina, and appears to associate primarily with ectomycorrhizal hardwoods but possibly also with conifers. Elaphomyces cibulae is widely distributed but disjunct from Florida, Mississippi, and North Carolina. Elaphomyces cibulae seems to primarily associate with Quercus species. Elaphomyces mitchelliae has the widest distribution of the three species, from Florida, Maryland, North Carolina, Virginia, and West Virginia, and appears to associate with either ectomycorrhizal hardwoods and/or conifers. In the course of comparing our new Elaphomyces species to previously described European species we discovered that E. persoonii var. minor is conspecific in all essential details with and thus a synonym of E. cyanosporus ., (© 2018 Westerdijk Fungal Biodiversity Institute.)
