Three new Xenasmatella (Polyporales, Basidiomycota) species from China

Three new wood-inhabiting fungal species, Xenasmatella rhizomorpha, X. tenuis and X. xinpingensis spp. nov., are proposed based on a combination of morphological characteristics and molecular BLAST analyses. Xenasmatella rhizomorpha is characterized by annual, resupinate, gossypine basidiomata with rhizomorphs, a monomitic hyphal system with clamped generative hyphae and ellipsoid, thin-walled, warted basidiospores measuring 3.1?4.9 ? 2.3?3.3 ?m. Xenasmatella tenuis is characterized by annual, resupinate, very thin basidiomata with ceraceous to membranous, white to lilac hymenial surface, a monomitic hyphal system with clamped generative hyphae and ellipsoid, thin-walled, warted basidiospores. Xenasmatella xinpingensis is characterized by annual, resupinate basidiomata, a monomitic hyphal system with clamped generative hyphae and subglobose to globose, thin-walled, warted basidiospores (3.5?4.9 ? 3?4.2 ?m).
