Three new species of (Agaricales, Inocybaceae) from Tropical Africa.

Here, we describe three new species of from Tropical Africa: , and . Morphological and molecular data show that these species have not been described before, hence need to be described as new. The phylogenetic placements of these species were inferred, based on molecular evidence from sequences of 28S and RPB2.

The taxonomy of the model filamentous fungus .

The filamentous fungus has been used as a model organism for more than 100 years and has proved to be an invaluable resource in numerous areas of research. Throughout this period, has been embroiled in a number of taxonomic controversies regarding the proper name under which it should be called. The most recent taxonomic treatment proposed to change the name of this important species to .

When mycologists describe new species, not all relevant information is provided (clearly enough).

Taxonomic mycology struggles with what seems to be a perpetual shortage of resources. Logically, fungal taxonomists should therefore leverage every opportunity to highlight and visualize the importance of taxonomic work, the usefulness of taxonomic data far beyond taxonomy, and the integrative and collaborative nature of modern taxonomy at large. Is mycology really doing that, though? In this study, we went through ten years' worth (2009-2018) of species descriptions of extant fungal taxa - 1,097 studies describing at most ten new species - in five major mycological journals plus one plant journal.

The genus (Catathelasmataceae, Basidiomycota) in China.

Two new species, and , are described on the basis of morphological characters, phylogenetic evidence, host preferences and geographic distributions. A taxonomic key to the known species in China is also provided to facilitate identification. Based on samples from temperate Asia, Europe and North America, the phylogeny of was reconstructed using the internal transcribed spacer (ITS) region, the large subunit (LSU) of the ribosomal DNA and the translation elongation factor 1-α (TEF1).

(Ramalinaceae, Lecanorales), a new lichen species from western North America.

S. Ekman & Tønsberg, a lichenised ascomycete in the family Ramalinaceae (Lecanorales, Lecanoromycetes), is described as new to science. It is distinct from other species of in the combination of mainly three-septate ascospores, a crustose thallus forming distinctly delimited soralia that develop by disintegration of convex pustules and the production of atranorin in the thallus and apothecia.
