Three new Clavulina species from Baiyun Mountain, Guangzhou, China

Three new Clavulina species, namely C. baiyunensis, C. minor, and C. lilaceorosea, were described from specimens collected from Baiyun Mountain, Guangzhou, China, based on detailed morphological studies and phylogenetic analyses of the nucleotide sequences of three loci (ITS, LSU, and RPB2). Clavulina baiyunensis is characterized by light brown to brown basidiomata with hyaline tramal hyphae. Clavulina minor has diminutive, dull white to pale brown basidiomata with hyaline tramal hyphae. Clavulina lilaceorosea has pale brown to ochre brown basidiomata with palmate branches, and light brown walls of tramal hyphae. All three new species have abundant clamp connections. A key to the known species of Clavulina from China is provided.
