Mycena cinereoalba sp. nov. from Qinghai province, China

Abstract

From specimens collected in Sanjiangyuan (Source of Three Rivers) region, Qinghai Province, China, Mycena cinereoalba is described based on its morphological characteristics and a molecular phylogenetic analysis using the internal transcribed spacer (ITS) region and nuclear ribosomal RNA large subunit (nrLSU) sequences. The phylogenetic relationship inferred from the ITS and nrLSU sequence data matrices confirmed that this new species is different from other species of Mycena for which DNA sequences are available. The species are comprehensively described and illustrated in detail with photographs. Phylogenetic relationships among the species were analyzed, and two phylograms were provided in this study.
