A revision of the genera Antromycopsis, Sclerostilbum, and Tilachlidiopsis (Hyphomycetes)
The anamorphic genera Antromycopsis, Sclerostilbum, and Tilachlidiopsis are revised. Three anamorph species with basidiomycetous affinities are accepted in Antromycopsis: A. macrocarpa (Ellis & Everh.) comb.nov. (basionym Stilbum macrocarpum), previously known as A. broussonetiae (teleomorph: Pleurotus cystidiosus), A. angustata sp.nov. for the presumed anamorph of Pleurotus angustatus, and A. guzmanii sp.nov. (teleomorph Pleurotus smithii). A description and illustration are presented of the type species of Tilachlidiopsis, T. racemosa, the anamorph of Collybia racemosa. Sclerostilbum is considered a taxonomic synonym of Tilachlidiopsis. Nothoclavulina ditopa, the anamorph of Arthrosporella ditopa, is illustrated and briefly discussed. Key words: anamorph–teleomorph connections, Antromycopsis, Sclerostilbum, Pleurotus, Collybia, nematophagous fungi.
