Abstract

Two new wood-inhabiting fungal species, Peniophorella fissurata and P. yunnanensis, are proposed based on a combination of morphological features and molecular evidence. Peniophorella fissurata is characterized by resupinate basidiomata with smooth to tuberculate hymenial surface, a monomitic hyphal system with clamped generative hyphae, fusiform cystidia, and allantoid, colorless, thin-walled, smooth basidiospores measuring 9–11 × 3–3.9 μm. Peniophorella yunnanensis is characterized by an annual basidiomata with grandinioid hymenial surface, a monomitic hyphal system with clamped generative hyphae, presence of three types cystidia, and ellipsoid, colorless, smooth, thin-walled basidiospores (8–9 × 4.7–5.5 μm). Sequences of ITS gene region of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. These phylogenetic analyses showed that P. fissurata was sister to P. pubera. Peniophorella yunnanensis formed a monomitic lineage and then grouped with P. odontiiformis and P. rude.
