New species of Catenularia and Fuscocatenula from Xishuangbanna, China

Abstract

Three new anamorphic fungi, Catenularia yunnanensis, Fuscocatenula nabanhensis and F. chinensis, are described and illustrated from specimens collected on dead branches of unidentified plants in Xishuangbanna, Yunnan Province, China. Catenularia yunnanensis is characterized by its acrogenous, basocatenate, aseptate, rounded- obconic, smooth conidia with 2–3 blunt corners at the distal end when viewed from above. Fuscocatenula nabanhensis is distinguished by its basocatenate, aseptate, cylindrical to slightly cuneiform, smooth conidia with protracted maturation and round outline. Fuscocatenula chinensis is denoted by its basocatenate, aseptate, obovoid, smooth conidia with round outline. The three species are described, illustrated, and compared with similar taxa. A key to species of Fuscocatenula is provided.
