Wood-inhabiting fungi (WIF), such as polypores, are extremely species-rich and play vital roles in the functioning of forest ecosystems as decomposers. Despite the importance of polypores, our knowledge of the diversity and distribution of these fungi is still poor in general and especially for West Africa. To advance our knowledge we here summaris...

Nagrajomyces ( incertae sedis , Ascomycota ) is a monotypic genus with a previously unknown systematic position. In this report, two new species are proposed, Nagrajomyces fusiformis and Nagrajomyces laojunshanensis. These new taxa are proposed based on morphological characteristics evident via light microscopy and molecular data. Multi-locus phylo...

Nolanea is a well-known and long-established subgenus of the genus Entoloma traditionally defined mainly by the mycenoid basidiocarps of the included species. Until now, revisions of this subgenus including molecular data exist only on a regional scale. In this study, the phylogeny of species of Nolanea is analysed based on multi-gene DNA sequences...

Fungi are highly diverse organisms, which provide multiple ecosystem services. However, compared with charismatic animals and plants, the distribution patterns and conservation needs of fungi have been little explored. Here we used high‐resolution sequencing to assess endemicity patterns, global change vulnerability and conservation priority areas...

The documentation of rust fungi in tropical Africa is very incomplete. For West Africa, 332 species of rust fungi (Pucciniales, Basidiomycota) are recorded, including only six species from Benin. By a recent survey of rust fungi in Benin, 22 specimens representing 11 species of Pucciniales were found. These species were identified based on morpholo...

In this investigation, we propose a new species in Telimena, T. bromeliae sp. nov. growing on bromeliads with a detailed description, illustrations, and molecular characterisation based on material collected in Costa Rica and Panama. Additionally, four species of Phyllachora occurring on non-graminicolous hosts are transferred into Telimena based o...

Hyperparasitism on plant-parasitic fungi is a widespread but rarely studied phenomenon. Here, for the first time, we compile in a checklist information provided by peer-reviewed literature for fungi growing on colonies of black mildews (Meliolales, Ascomycota), a species-rich group of tropical and subtropical plant-parasitic microfungi. The checkli...

Kálmán Vánky (15 th of June 1930-18 th of October 2021) was arguably the most prolific researcher of smut fungi so far. He published more than 1000 taxonomic novelties, and crowned his outstanding oeuvre with the most comprehensive monograph of the smut fungi (Smut Fungi of the World) written to date.

Understanding and describing the diversity of living organisms is a great challenge. Fungi have for a long time been, and unfortunately still are, underestimated when it comes to taxonomic research. The foundations were laid by the first mycologists through field observations. These important fundamental works have been and remain vital reference w...

Entoloma (Agaricales, Basidiomycota) is a species-rich genus with approximately 2000 species known worldwide. In Cen- tral America, however, information about the species of this genus is sparse, despite the generally high biodiversity in this region. Recently, 124 specimens of Entoloma were collected in Panama, Chiriquí Province. In the present pu...

Panama forms part of the Central American biodiversity hotspot, one of the most important biodiversity hotspots in the world. While plants are relatively well studied in Panama, the documentation of fungal diversity is still in a pioneer phase. In this publication, four species of Agaricomycetes recently collected in Panama are described as new to...

A Ramularia-like hyphomycete was discovered on uredinia of Phakopsora ampelopsidis on leaves of wild Ampelopsis brevipedunculata and cultivated Parthenocissus tricuspidata in several cities in Taiwan. The micromorphology of this fungicolous fungus is similar to that of species of the genus Ramularia which are mostly plant parasites but some species...

Fungi are highly important biotic components of terrestrial ecosystems, but we still have a very limited understanding about their diversity and distribution. This data article releases a global soil fungal dataset of the Global Soil Mycobiome consortium (GSMc) to boost further research in fungal diversity, biogeography and macroecology. The datase...

Species of the genus Russula are key components of ectomycorrhizal ecosystems worldwide. Nevertheless, their diversity in the tropics is still poorly known. This study aims to contribute to the knowledge of the diversity of Russula species classified in subsection Roseinae based on specimens recently collected in tropical montane rainforests in wes...

The radioactive contamination of edible mushrooms increases human health hazards, especially in high mushroom collection intensity areas. Today only coarse-scale data with low spatial resolution are available, which prevents us from predicting human risk. To reduce the risk for human health, we need spatially explicit recommendations at landscape-s...

Since the circumscription of the genera Phyllachora and Telimena has been emended, several neotropical nongraminicolous species of Phyllachora have been transferred to Telimena, and several species of Telimena have been newly described. In order to better understand the species diversity and taxonomy of neotropical tar spot fungi, symptomatic leave...

A high number of fungal strains were isolated from roots of Brassicaceae species collected across western and southern Europe, resulting in an unexpectedly rich collection of Cadophora species. These isolates enable us to present a new and comprehensive view of the ecological, morphological, and phylogenetic traits of root-inhabiting members of thi...

Abstract Scientific information about biodiversity distribution is indispensable for nature conservation and sustainable management of natural resources. For several groups of animals and plants, such data are available, but for fungi, especially in tropical regions like West Africa, they are mostly missing. Here, information for West African count...

The pleosporalean anamorph Hermatomyces amphisporus is recorded for the first time from the U.S.A. based on several specimens collected on Sabal minor (Arecaceae) duringmycological surveys carried out in the state of Texas. Phylogenetic analyses of novel DNA sequence data belonging to four nuclear regions (ITS rDNA, EF1-�, RBP2, �-TUB) revealed its...

Species of the ectomycorrhizal genus Lactifluus , and often entire sections, are typically unique to a single continent. Given these biogeographic patterns, an interesting region to study their diversity is Central America and the Caribbean, since the region is closely connected to and often considered a part of the North American continent, but bi...

Powdery mildews are common pathogens on wild elm trees as well as on planted ornamentals in Asia and Europe. The taxonomy of the powdery Erysiphe species on elms (Ulmus spp., Ulmaceae) is complicated by taxonomical changes and inconsistently labelled DNA data in databases and publications. Based on morphology and phylogenetic analysis of new collec...

The Brachybasidiaceae are a family of 22 known species of plant-parasitic microfungi belonging to Exobasidiales, Basidiomycota. Within this family, species of the largest genus Kordyana develop balls of basidia on top of stomatal openings. Basidial cells originate from fungal stroma filling substomatal chambers. Species of Kordyana typically infect...
