Phylloporia lonicerae (Hymenochaetales, Basidiomycota), a new species on Lonicera japonica from Japan and an identification key to worldwide species of Phylloporia.

ABSTRACT: Phylloporia, in the Hymenochaetaceae, is a polypore genus with a worldwide distribution. The new taxon Phylloporia lonicerae is introduced, which is the first Phylloporia species to originate from Japan. This species grows exclusively on living Lonicera japonica and is distinguished by annual, sessile basidiocarps that occur in clusters, pileal surface of narrow, concentrically sulcate zones, 6-8 pores per mm, duplex context separated by a black zone, dimitic hyphal system and broadly ellipsoid basidiospores, 3.2-4 × 2.3-3.1 µm. Phylogenetically, P. lonicerae is nested within the Phylloporia clade as a distinct terminal lineage with full statistical supports and sister to the clade of P. minutispora, P. cf. pulla and P. terrestris with weak supports. Besides Phylloporia bibulosa, P. chrysites and P. spathulata, P. lonicerae is the fourth species of Phylloporia recorded from Japan. An identification key to all accepted 48 species of Phylloporia is provided.

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.
