Three new species of Cantharellales and Hymenochaetales from Pinus massoniana in China

Three new wood-inhabiting fungi species, found on Pinus massoniana , are proposed, based on a combination of morphological features and molecular evidence. Botryobasidium massonianae , belonging to Cantharellales , is characterised by fluffy, pellicular basidiomata, hypochnoid hymenophoral surface, generative hyphae simple septate, basidia with four to six sterigmata and basidiospores measuring 6.3–9.2 × 2.8–3.9 µm. Peniophorella crassibasidiata , belonging to Hymenochaetales , is characterised by soft coriaceous basidiomata, thick-walled generative hyphae, the presence of three types of cystidia, cylindrical basidiospores measuring 8.4–12.4 × 3.1–4.2 µm. Peniophorella variegata , belonging to Hymenochaetales , is characterised by farinaceous basidiomata, smooth hymenophoral surface, three types of cystidia, the presence of hyphidia and basidiospores measuring 7.9–10.8 × 3.9–5.1 µm. Phylogenetic analyses of the combined ITS+nLSU dataset using Maximum Likelihood and Bayesian Inference confirmed that one new species belongs to the genus Botryobasidium (Cantharellales) , the other two new species belong to the genus Peniophorella (Hymenochaetales) , respectively. Phylogenetically related and morphologically similar species to these three new species are discussed.
