New Asian records and morphological variation in Fibrodontia brevidens (Basidiomycota)

Abstract

Abstract — Fibrodontia brevidens (Trechisporales) is reported for the first time from Taiwan, mainland China, and Vietnam. Asian specimens are compared morphologically with collections from Venezuela. Morphological variation in the species is discussed. Most variable features within the specimens are encrustation of projecting skeletal-like hyphae (from totally naked to richly encrusted) and spore size. Nevertheless, the single morphospecies concept of F. brevidens is retained. Basidioma photographs, microscopical drawings, and scanning electron microscopic photographs of crystalline deposits on skeletal-like hyphae of this species are provided.
