In this study, we describe a new species, Cystoderma lignicola, collected from rotten woods in the temperate region in Yunnan Province, southwestern China. Our new species was described based on macro- and micro-morphological characteristics and molecular data of combined internal transcribed spacers (ITS) and large subunit (nrLSU) of the nuclear ribosomal DNA (rDNA) sequences. Cystoderma lignicola is characterized by its light orange to brown cap, globose, subglobose, ellipsoid to broadly ellipsoid basidiospores, with 4–5 × 3–4 μm diam. Phylogenetically, C. lignicola showed a sister clade to C. chocoanum with statistical support of SH-aLRT/UFB = 90.9/90 in maximum likelihood analysis and statistical support of BPP = 0.99 in the Bayesian analysis.
