摘要
Based on morphological characteristics and molecular phylogenetic analysis using nuc rDNA ITS1-5.8S-ITS2 and 28S rDNA sequences, two new species of Physisporinus, Physisporinus castanopsidis sp. nov. and Physisporinus roseus sp. nov. are described from Yunnan Province, Southwest China. Physisporinus castanopsidis is characterised by resupinate, snow white and waxy basidiocarps which become pale brown when bruised, abundant hymenial cystidia and cystidia-like hyphae at dissepiment edge, generative hyphae with swollen tips, distinctly ovoid basidiospores measuring 4.8–5.6 × 3.6–4.2 μm and growing on rotten wood or roots of Castanopsis. Physisporinus roseus is characterised by perennial, resupinate and thick basidiomata with rose fresh pores which becoming vinaceous grey up on drying, a distinct context layer present among tube layers, abundant clavate, smooth cystidia and subglobose basidiospores measuring 3.5–4.1 × 3.1–3.8 μm.
