Infundibulicybe trachyspora, a New Species from Northeastern China Based on Morphology and Molecular Phylogeny

Infundibulicybe trachyspora is described as a new species from northeastern China. The species is characterized by clitocyboid to omphalioid habit, carneous, greyish-yellow to brownish pileus, brown to dark reddish-brown, longitudinally fibrillose-striate stipe, non-amyloid, non-smooth spores, the a...

Description
Summary:Infundibulicybe trachyspora is described as a new species from northeastern China. The species is characterized by clitocyboid to omphalioid habit, carneous, greyish-yellow to brownish pileus, brown to dark reddish-brown, longitudinally fibrillose-striate stipe, non-amyloid, non-smooth spores, the absence of cystidia and the presence of clamp connections. A comprehensive description of the species is provided together with photo-illustrations and comparisons with phenotypically similar and phylogenetically related species. The nuclear ribosomal internal transcribed spacer (ITS) region and the nuclear, large subunit rDNA (nrLSU) region of the new species was sequenced and analyzed. The phylogenetic analysis supported the novelty of the species and its placement within the genus. Furthermore, a discussion on the proposal to establish a new section is made, and a key is provided for the Infundibulicybe species reported from China.
