Three new species of Peniophorella (Basidiomycota) from East Asia
Three new Peniophorella species (Hymenochaetales) growing on dead wood, are described and illustrated. Peniophorella aspersa was collected in Taiwan and mainland China, and characterized by minutely warted hymenial surface, well-developed subiculum, rare stephanocysts and cylindrical-suballantoid spores. Peniophorella crystallifera collected in mainland China, Taiwan and Japan, is distinguished by sparsely grandinioid hymenial surface, immersed heavily encrusted cystidia, stephanocysts and ellipsoid-subcylindrical spores. The characteristic features of P. reticulata, found in Taiwan, are minutely porulose, odontioid basidiomata, provided with peg-like groups of hyphae, stellate crystalline incrustations on hyphal ends and oblong-ellipsoid spores. Maximum likelihood and Bayesian phylogenetic reconstructions based on ITS and 28S sequences demonstrated that P. aspersa and P. reticulata belong to the same group of species, and the all three species are most closely related to P. praetermissa and P. rude.
