A new species of Perenniporia (Polyporales, Basidiomycota) described from southern China based on morphological and molecular characters

Abstract

A new poroid wood-inhabiting basidiomycete, Perenniporia nanlingensis, collected in Guangdong Province, southern China, is described and illustrated on the basis of three collections. Both the morphology and phylogenetic analysis of rDNA ITS sequences support this new species. Macroscopically, the new species is characterized by an annual growth habit, resupinate basidiocarps with pinkish buff to cinnamon-buff pore surface when dry. Microscopically, it has a trimitic hyphal system, slightly dextrinoid and cyanophilous skeletal and binding hyphae, and its basidiospores are ellipsoid, truncate, strongly dextrinoid and cyanophilous, 9.0–9.8 × 5.0–5.9 μm.
