Morphological and molecular identification of two new wood-inhabiting macrofungi (Basidiomycota) from Yunnan-Guizhou Plateau, China

Year: 2024

Type: article

Abstract: Two new species of wood-inhabiting fungi viz. Luteoporia flavula and Xylodon subpunctus are described from the Yunnan-Guizhou Plateau in southwestern China. Luteoporia flavula is characterized by annual basidiomata with an odontioid and lemon-chrome hymenophore, a monomitic hyphal structure with clamped generative hyphae, subuliform cystidia, and oblong-ellipsoid basidiospores (4–5.2 × 2.3–3.2 μm). The phylogenetic analysis based on ITS sequences indicated that Luteoporia flavula formed a single lineage and was nested within the genus Luteoporia. Xylodon subpunctus is characterized by annual basidiomata with a coriaceous and buff hymenophore, a monomitic hyphal structure with clamped generative hyphae, capitate and fusiform cystidia, ellipsoid to ovoid basidiospores measuring 5.5–7.2 × 2.5–3.6 μm. Xylodon subpunctus is clustered into the genus Xylodon, in the family Schizoporaceae, with Hyphodontia, Lyomyces, and Schizopora. Descriptions, illustrations, and phylogenetic analysis results of two new species are provided.
