The anamorphic generaAntromycopsis,Sclerostilbum, andTilachlidiopsisare revised. Three anamorph species with basidiomycetous affinities are accepted inAntromycopsis:A. macrocarpa(Ellis & Everh.) comb.nov. (basionymStilbum macrocarpum), previously known asA.broussonetiae(teleomorph:Pleurotus cystidiosus),A. angustatasp.nov. for the presumed anamorph ofPleurotus angustatus, andA. guzmaniisp.nov. (teleomorphPleurotus smithii). A description and illustration are presented of the type species ofTilachlidiopsis,T.racemosa, the anamorph ofCollybia racemosa.Sclerostilbumis considered a taxonomic synonym ofTilachlidiopsis.Nothoclavulina ditopa, the anamorph ofArthrosporella ditopa, is illustrated and briefly discussed.Key words: anamorph–teleomorph connections,Antromycopsis, Sclerostilbum,Pleurotus,Collybia, nematophagous fungi.
