New corticioid taxa in Phanerochaetaceae (Polyporales, Basidiomycota) from East Asia.

ABSTRACT: The species diversity, taxonomy, and phylogeny of five corticioid genera of Phanerochaetaceae, namely, Hyphodermella, Roseograndinia, Phlebiopsis, Rhizochaete, and Phanerochaete, in East Asia are studied by using the morphological and molecular methods. Phylogenetic analyses were performed separately for the Donkia, Phlebiopsis, Rhizochaete, and Phanerochaete clades based on ITS1-5.8S-ITS2 and nrLSU sequence data. In total, seven new species were found, two new combinations are suggested, and a new name is proposed. In the Donkia clade, Hyphodermella sensu stricto was strongly supported with two new lineages, namely H. laevigata and H. tropica, which were recovered. Hyphodermella aurantiaca and H. zixishanensis are members of Roseograndinia, while R. jilinensis is proved to be a later synonym of H. aurantiaca. In the Phlebiopsis clade, P. cana sp. nov. was found on the bamboo from tropical Asia. In the Rhizochaete clade, four new species, R. nakasoneae, R. subradicata, R. terrestris, and R. yunnanensis were recovered based mainly on molecular analyses. In the Phanerochaete clade, P. subsanguinea nom. nov. is proposed to replace Phanerochaete rhizomorpha C.L. Zhao & D.Q. Wang, which is an invalid name because it was published after Phanerochaete rhizomorpha C.C. Chen, Sheng H. Wu & S.H. He, representing another species. Descriptions and illustrations are provided for the new species, and discussions are given for new taxa and names. Identification keys to Hyphodermella species worldwide and Rhizochaete species in China are given separately.

Project description:Five new wood-inhabiting fungi, Lyomycesalbopulverulentus, L.yunnanensis, Xylodondaweishanensis, X.fissuratus, and X.puerensisspp. nov., are proposed based on a combination of morphological features and molecular evidence. Lyomycesalbopulverulentus is characterized by brittle basidiomata, pruinose hymenophore with a white hymenial surface, a monomitic hyphal system with clamped generative hyphae, and ellipsoid basidiospores. Lyomycesyunnanensis is characterized by a grandinioid hymenial surface, the presence of capitate cystidia, and ellipsoid basidiospores. Xylodondaweishanensis is characterized by an odontioid hymenial surface, a monomitic hyphal system with clamped generative hyphae, and broad ellipsoid-to-subglobose basidiospores. Xylodonfissuratus is characterized by a cracking basidiomata with a grandinioid hymenial surface, and ellipsoid basidiospores. Xylodonpuerensis is characterized by a poroid hymenophore with an angular or slightly daedaleoid configuration, and ellipsoid-to-broad-ellipsoid basidiospores. Sequences of ITS and nLSU rRNA markers of the studied samples were generated and phylogenetic analyses were performed with the maximum likelihood, maximum parsimony, and Bayesian inference methods. The phylogram based on the ITS+nLSU rDNA gene regions (Fig. 1) included six genera within the families Chaetoporellaceae, Hyphodontiaceae, Hymenochaetaceae, and Schizoporaceae (Hymenochaetales)-Fasciodontia, Hastodontia, Hyphodontia, Kneifiella, Lyomyces, and Xylodon-in which the five new species were grouped into genera Lyomyces and Xylodon. The phylogenetic tree inferred from the ITS sequences highlighted that Lyomycesalbopulverulentus formed a monophyletic lineage and was then grouped closely with L.bambusinus, L.orientalis, and L.sambuci; additionally, L.yunnanensis was sister to L.niveus with strong supports. The topology, based on the ITS sequences, revealed that Xylodondaweishanensis was retrieved as a sister to X.hyphodontinus; X.fissuratus was grouped with the four taxa X.montanus, X.subclavatus, X.wenshanensis, and X.xinpingensis; and X.puerensis was clustered with X.flaviporus, X.ovisporus, X.subflaviporus, X.subtropicus, and X.taiwanianus.
