Abstract
A complete taxonomic and phylogenetic study on corticioid and hydnoid (Hymenochaete and Hydnoporia) Hymenochaetaceae was carried out. Phylogenetic analyses were based on multigenes including the internal transcribed spacer regions (ITS), the large subunit of nuclear ribosomal RNA gene (nLSU) and the small subunit mitochondrial RNA gene (mtSSU). The mtSSU of Hymenochaete was amplified for the first time. A total of 660 sequences from 354 specimens representing 316 species was used in the phylogenetic analyses, of which 290 sequences were newly generated, including 125 ITS, 89 nLSU and 76 mtSSU sequences. Among 354 specimens, 297 represent 160 taxa from Hymenochaete and Hydnoporia. In this study, 44 new species, including five new species of Hydnoporia as Hydnoporia cinnamomea, H. conifera, H. fulvimarginata, H. imbricata and H. radiata, and 39 new species of Hymenochaete as Hymenochaete adnata, H. alpina, H. asiatica, H. atrobrunnea, H. austrosinensis, H. brunnea, H. cinerea, H. cinereoalba, H. conifericola, H. cylindrospora, H. dichotoma, H. erastii, H. flava, H. granulata, H. hainanensis, H. hubeiensis, H. leveillei, H. iliensis, H. luteomarginata, H. major, H. membranacea, H. moniliformis, H. montana, H. niveomarginata, H. piceae, H. puerensis, H. ramicola, H. rubrobrunnea, H. setulohypha, H. sichuanensis, H. stereoidea, H. subepichlora, H. subfissurata, H. subinnexa, H. subluteobadia, H. subrhabarbarina, H. variabilis, H. vitellina and H. vivida, are described. Illustrated descriptions, voucher specimens, hosts, distribution and remarks for these 44 new species are provided. The phylogenetic analyses confirmed that the two genera Hymenochaete and Hydnoporia formed two distinct clades within the Hymenochaetaceae. The phylogenetic relationships and morphological distinctions between these two genera are also discussed. This study recognizes 249 species in Hymenochaete and Hydnoporia and a worldwide annotated checklist is provided.
期刊介绍：
Fungal Diversity, the official journal of the Kunming Institute of Botany of the Chinese Academy of Sciences, is an international, peer-reviewed journal covering all aspects of mycology. It prioritizes papers on biodiversity, systematic, and molecular phylogeny. While it welcomes novel research and review articles, authors aiming to publish checklists are advised to seek regional journals, and the introduction of new species and genera should generally be supported by molecular data.
Published articles undergo peer review and are accessible online first with a permanent DOI, making them citable as the official Version of Record according to NISO RP-8-2008 standards. Any necessary corrections after online publication require the publication of an Erratum.
