Phlebiporia bubalina gen. et. sp nov (Meruliaceae, Polyporales) from southwest China with a preliminary phylogeny based on rDNA sequences

摘要

A new genus, Phlebiporia, is proposed, based on morphological characters and molecular data. It is typified by P. bubalina sp. nov., characterized by an annual growth habit, resupinate basidiomata, a monomitic hyphal system with simple septa, dextrinoid and thick-walled generative hyphae, presence of thin-walled quasi-binding hyphae in the subiculum, and small, smooth, ellipsoid basidiospores. Phylogenetic analysis of P. bubalina and its related species was inferred from ITS and nLSU rDNA sequences, which indicate that it belongs to Meruliaceae
