Allophlebia, a new genus to accomodate Phlebia ludoviciana (Agaricomycetes, Polyporales)
Allophlebia is proposed as a new genus in Meruliaceae based on morphological characters and molecular data. The genus, so far monotypic, is typified by Peniophora ludoviciana and the new combination A. ludovician...

Open AccessStudies in the Basidiodendron caesiocinereum complex (Auriculariales, Basidiomycota)
Taxonomy of Basidiodendron caesiocinereum complex is revised based on morphological and molecular methods (with the use of nc LSU rDNA, ITS and TEF1 regions). The basidiospore ornamentation is justified as a key ...

Open AccessCompeting sexual-asexual generic names in Agaricomycotina (Basidiomycota) with recommendations for use
With the change to one scientific name for fungal taxa, generic names typified by species with sexual or asexual morph types are being evaluated to determine which names represent the same genus and thus compe...

Open AccessOn Sistotremastrum and similar-looking taxa (Trechisporales, Basidiomycota)
The taxonomy of Sistotremastrum (Trechisporales, Basidiomycota) is revised based on morphology and DNA data. The genus is shown to be polyphyletic, and therefore it is split into two units—Sistotremastrum s. str....

Additions to Trechispora and the status of Scytinopogon (Trechisporales, Basidiomycota)
Three new species of Trechispora from Brazil, T. copiosa, T. gelatinosa, and T. termitophila, are described and illustrated. The new species are microscopically similar to the known Trechispora species, but diffe...

Taxonomic novelties in Trechispora (Trechisporales, Basidiomycota) from Brazil
Collections from field expeditions to the Atlantic Forest and to Amazonia in Brazil and revision of herbarium material revealed the presence of Trechispora specimens that could not be assigned to any described sp...

FungalTraits: a user-friendly traits database of fungi and fungus-like stramenopiles
The cryptic lifestyle of most fungi necessitates molecular identification of the guild in environmental studies. Over the past decades, rapid development and affordability of molecular tools have tremendously ...

Open AccessMorphologically similar but not closely related: the long-spored species of Subulicystidium (Trechisporales, Basidiomycota)
Species boundaries and geographic distribution of corticioid fungi (resupinate Basidiomycota) are often poorly known. Our recent study on Subulicystidium showed that species diversity in this genus is at least tw...

Open AccessOn Protomerulius and Heterochaetella (Auriculariales, Basidiomycota)
The taxonomy of Protomerulius and Heterochaetella is revised based on DNA data and morphological evidence, and their type species, P. brasiliensis and H. dubia, are proved to be congeneric. As a consequence, H. d...

Open AccessStudies in the Stypella vermiformis group (Auriculariales, Basidiomycota)
Stypella vermiformis is a heterobasidiomycete producing minute gelatinous basidiocarps on rotten wood of conifers in the Northern Hemisphere. In the current literature, Stypella papillata, the genus type of Stype...

Open AccessOn Craterocolla and Ditangium (Sebacinales, Basidiomycota)
In the present paper, we select a neotype for Tremella cerasi and prove that it is conspecific with Ditangium insigne (the genus type of Ditangium). We argue that Ditangium should be restored as a correct genus f...

Article
Revision of Protohydnum (Auriculariales, Basidiomycota)
Three species currently addressed to Protohydnum (Auriculariales) are studied with morphological and DNA methods. The genus Protohydnum is retained for the type species only, P. cartilagineum, recently re-collect...

Open AccessConsiderations and consequences of allowing DNA sequence data as types of fungal taxa
Nomenclatural type definitions are one of the most important concepts in biological nomenclature. Being physical objects that can be re-studied by other researchers, types permanently link taxonomy (an artific...

Studies in the Phaeotremella foliacea group (Tremellomycetes, Basidiomycota)
The taxonomy of the Phaeotremella foliacea group is revised based on morphological, ecological, geographic and DNA data. The name P. foliacea is retained for the gymnosperm-dwelling species associated with Stereu...

What is the type species of Phanerochaete (Polyporales, Basidiomycota)?
Phanerochaete velutina and the closely related species P. alnea, P. alnea subsp. lubrica, and P. rhodella are identified as distinct species based on morphological criteria and molecular ...

Two new Trechispora species from La Réunion Island
Two new species of corticioid Basidiomycota are described: Trechispora cyatheae Ordynets, Langer & K.H. Larss. sp. nov., and T. echinocristallina Ordynets, Langer & K.H. Larss. sp. nov. Both species were repeated...

Open AccessMolecular analyses confirm Brevicellicium in Trechisporales
The genus Brevicellicium encompasses wood-inhabiting corticioid fungi characterized by isodiametric subhymenial hyphae, short basidia, and smooth, often subangular spores with a distinct apiculus. Eight new LSU n...

Morphology, anatomy, and molecular studies of the ectomycorrhiza formed axenically by the fungus Sistotrema sp. (Basidiomycota)
Several species of the corticioid (resupinate) genus Sistotrema of the cantharelloid clade (Basidiomycota) were recently found to be ectomycorrhizal. This changed the traditional assertion that all Sistotrema spe...
