Morphological and molecular evidence for a new species of Psilocybe from southern China

Psilocybe cinnamomea sp. nov. is reported from China. It is characterized by its campanulate to plano-convex pileus, ellipsoid spores with a distinctly broad germ pore, clavate basidia, polymorphic cheilocystidia, and clavate to fusiform pleurocystidia with a short unbranched neck. Phylogenetic relationships among the new species and allied species in the genus were inferred from the internal transcribed spacer (ITS) region.
