Abstract

Based upon studies of type specimens six species of Stemonitales are redescribed and illustrated: Comatricha microcarpa, C. laxa, C. nigricapillitium, Stemonitis fusca and S. nigrescens are critically reviewed and illustrated. Comatricha microcarpa is considered to be a nomen ambiguum, and Stemonitis nigrescens is treated as an extreme form of S. fusca. S. virginiensis is recognized as a rare species distinct from the smaller forms of S. fusca. Comatricha nigricapillitium comb. nov. is proposed for Lamproderma nigricapillitium.
