New trichomycete species from China and additional information on Gauthieromyces

Abstract

We describe three new species of gut fungi (Kickxellomycotina, Harpellales) from aquatic insects, including Caudomyces typhella from a crane fly larva and Genistelloides torrentis and Orphella sinica from stonefly nymphs. Details on trichomycete species previously reported from Asia, including China, are provided. Recent descriptions of two new species of Gauthieromyces provide a more complete understanding of the genus; it is emended to reflect this new information and an epitype is designated. The description of G. indicus is emended based on an examination of the type specimen and additional collections of this species from China.
