Two new Harpellales inhabiting the digestive tracts of midge larvae and other trichomycetes from Tianshan Mountains, China

Abstract

Two new taxa of gut fungi within order Harpellales (Kickxellomycotina) are described from a stream in the Tianshan Mountains in northwestern China. These include the new genus and species, Sinotrichium chironomidarum J. Wang, S.Q. Xu & Strongman, and the new species, Stachylina tianensis J. Wang, S.Q. Xu & Strongman, both living in the guts of aquatic chironomid larvae. We also extend the geographic range of Smittium rupestre, previously known only from Australia. A Harpellid specimen not fully identified and a species of Paramoebidium (Amoebidiales) also are documented.
