Two new species of the Entoloma quadratum–Murrayi complex in Japan.

ABSTRACT: We describe two new species, Entoloma. kermesinum sp. nov. and E. flavescens sp. nov., which are confused with E. quadratum and E. murrayi, respectively. We sequenced the large subunit of mitochondrial ribosomal RNA, the nuclear ribosomal internal transcribed spacer region and 22 single-copy genes for 51 specimens of E. kermesinum, E. flavescens, E. album, and related species. Species boundaries were assessed using the molecular phylogenetics and population genetics approaches. Specimens of E. kermesinum, E. flavescens, and E. album formed independent clades, which were phylogenetically distinct from the specimens of E. quadratum and E. murrayi collected around the type locality (i.e., New England). Although the phylogenetic distance between E. flavescens and E. album was small, gene flow
