Crepidotus crocophyllus, one of the most common species of the genus Crepidotus (Basidiomycota, Fungi)in Japan, were morphologically and phylogenetically reexamined based on the materials collected from Choshi, Chiba Prefecture, Central Japan. Morphologically, Japanese C. crocophyllus were well match with previous descriptions of the present species based on European and American materials. To reveal the phylogenetic placement of Japanese specimens of C. crocophyllus, molecular phylogenetic analysis of the present species were conducted. By maximum parsimony analysis of nuclear rRNA ITS region, materials of C. crocophyllus collected from Japan (Choshi, Chiba) and North America (USA) were placed within well-supported, different clades each other. The present analysis revealed for the first time that Japanese and North American specimens of C. crocophyllus are polyphyletic, and a taxonomic revision of the species tentatively identified as C. crocophyllus is therefore needed.
