Bambusicolous fungi in Japan (8): a new species of Pseudolachnella from Yakushima Island, southern Japan

A coelomycetous fungus occurring on culms of Pleioblastus sp. in Yakushima Island, southern Japan, is described and illustrated as a new species, Pseudolachnella yakushimensis. The species is characterized by cupulate, superficial black setose conidiomata, and cylindrical 3-septate conidia with two to five appendages at each end. Pseudolachnella yakushimensis is similar to P. indica and P. scolecospora by its 3-septate conidia, but is different from them by its smaller conidia with more than two appendages.
