Hypochnicium sensu lato (Polyporales, Basidiomycota) from Japan, with descriptions of a new genus and three new species
Species of Hypochnicium (Polyporales, Basidiomycota) collected from Japan were studied on their taxonomy by morphological and phylogenetic approaches. Phylogenetic analyses based on a nrDNA LSU and ITS dataset including the Japanese specimens and other publicly available ones show that Hypochnicium...

description | Species of Hypochnicium (Polyporales, Basidiomycota) collected from Japan were studied on their taxonomy by morphological and phylogenetic approaches. Phylogenetic analyses based on a nrDNA LSU and ITS dataset including the Japanese specimens and other publicly available ones show that Hypochnicium is polyphyletic. Since the clade containing the type species H. bombycinum was well-supported, we defined this clade as Hypochnicium s. str., and emended Hypochnicium to include restricted taxa with only smooth basidiospores. The new genus Neohypochnicium is proposed to accommodate the remaining taxa excluded from the genus Hypochnicium s. str., which includes both species with smooth basidiospores and ornamented ones. Three new species, Gyrophanopsis japonica, N. asiaticum and N. perlongicystidiosum are described and illustrated based on morphological and phylogenetic analyses using an ITS region dataset. In addition, the following 15 new combinations are proposed: N. albostramineum, N. aotearoae, N. capitulateum, N. cremicolor, N. cystidiatum, N. geogenium, N. guineense, N. huinayense, N. michelii, N. microsporum, N. patagonicum, N. pini, N. punctulatum, N. subrigescens and N. wakefieldiae. An identification key to Japanese species of Bulbillomyces, Gyrophanopsis, Hypochnicium and Neohypochnicium is provided. |
