Sinotrichium was erected by Wang et al. (2010) as a new gut fungus within the order Harpellales and the family Legeriomycetaceae (Kickxellomycotina). The genus is typified by Sinotrichium chironomidarum J. Wang, S.Q. Xu & Strongman, and was isolated from the guts of aquatic chironomid larvae from a stream in the Tianshan Mountains in northwestern China. Sinotrichium is characterized by dense, regularly branched thallus, long cylindrical trichospores which have a collar and one long appendage at the base, and zygospores with a collar and numerous coarse appendages that are biconical and affixed obliquely to the zygosporophores. This combination of traits is sufficiently different to warrant erecting a new genus Sinotrichium (Wang et al. 2010).

Type species: Sinotrichium chironomidarum Juan Wang, S.Q. Xu & Strongman
