Abstract

A new species in genus Neohygrocybe sect. Neohygrocybe, N. griseonigra, is described from the Chebaling National Nature Reserve in Guangdong province, China. It is characterized by its dark brown dry fibrillose pileus, whitish to grayish white lamellae that stain red then dark gray or blackish when bruised, smooth basidiospores, long sterigmata of basidia, and lanceolate pseudocystidia. Molecular phylogenetic analyses based on the ITS rDNA sequences also confirm the taxonomic status of the new species as the morphological characters indicated. A key to all known members of Neohygrocybe is provided in this study.
