A taxonomic re-evaluation of <i>Hymenostilbe mycetophila</i>, a hyperparasitic synnematous hyphomycete on <i>Favolaschia nipponica</i>, with <i>Kobayasiyomyces mycetophilus</i> gen. et comb. nov. (<i>Leotiales</i>).

ABSTRACT: About 70 y after the first report by Yosio Kobayasi, we collected a little-known synnematous hyphomycete, Hymenostilbe mycetophila, on decaying basidiocarps of Favolaschia nipponica growing on dead culms of two bamboo species in Tateyama (on Sasa kurilensis), Chichibu (type locality of H. mycetophila; on Sasamorpha borealis), and Shigakogen (on S. kurilensis) in Japan, and obtained isolates of both the parasite and its host. Kobayasi provided only brief Latin and Japanese descriptions and quite elementary illustrations for H. mycetophila, without depositing any herbarium specimens including the holotype. In this paper, a lectotype and an epitype of this species are designated respectively from the original protolog (illustration) of Kobayasi
