A new species and two new records of Stemonitidaceae from China

摘要

A new species of Stemonitidaceae, Comatricha clavicolumella, collected in Jigong Mountain Scenic Area, Henan Province, China, is described. C. clavicolumella has a columella that usually ends in a clavate expansion at the apex of the sporocysts, and has smaller spores than usual for the genus (about 5-5.5 mu m in diam.). Two newly recorded species from China, C. ellae and C. reticulospora, are also described. We present a scanning electron micrograph study of the species.
