The order Melanosporales comprises a large group of ascomycetes, most of them mycoparasites, characterized by the production of usually ostiolate, translucent ascomata, unitunicat…

Multilocus phylogenetic studies revealed a high level of cryptic diversity within the lichen-forming fungal genus Maronina (Protoparmelioideae, Parmeliaceae). Coalescent-based spe…

Five species of Hydnum have been generally recognized from eastern North America based on morphological recognition: H. albidum, H. albomagnum, H. repandum and varieties, H. rufes…

Xylopsora canopeorum Timdal, Reese Næsborg & Bendiksby is described as a new species occupying the crowns of large Sequoia sempervirens trees in California, USA. The new species i…

Molecular analyses have revealed a clade which equates with the genus name Mycetinis Earle. An overall survey of this genus, however, has not been forthcoming. The current study s…

DNA sequences show that the traditional genus Micromphale appears to be polyphyletic. Nuclear ribosomal LSU and ITS DNA sequences place Micromphale sect. Perforantia Singer (typus…

We explored whether DNA-phylogeny-based and morphology-based genus concepts can be reconciled in the basidiomycete family Phanerochaetaceae. Our results show that macromorphology …

The authors apologize for errors in the description of type specimens in their original article and make corrections.

Inocybe insignis, an eastern North American species with greenish blue staining basidiomes, is documented for the first time since its original description circa 75 years ago in t…

Five new species from Cortinarius sect. Cortinarius are formally described, four from the Americas (Cortinarius palatinus Harrower, sp. nov., Cortinarius atrotomentosus Harrower, …

Phylogeographic data indicate that DNA differences consistently exist between the North American and European allopatric populations of Gymnopus confluens. Conversely, pairing exp…

Two species of Ramaria from the Ozark region of Arkansas, USA, R. admiratia and R. calvodistalis, are proposed as new. They are described morphologically and placed molecularly wi…

Cortinarius bovarius sp. nov., a conifer associated taxon growing on calcareous ground, is described from western North America. Phylogenetic relationships and species limits were…
