A new species of Wrightoporiopsis (Russulales, Basidiomycota) and a key to accepted species in the genus

Abstract

Wrightoporiopsis YC Dai, Jia J Chen & BK Cui, typified by W. neotropica (Ryvarden) YC Dai, Jia J Chen & BK Cui, was recently established by Chen et al.1 Some of taxa in the genus were previously treated under Wrightoporia Pouzar.2–4 However, Phylogenetic analysis demonstrated that Wrightoporiopsis is distant from Wrightoporia sensu stricto, and these two genera in fact belong to two families, Hericiaceae and Wrightoporiaceae, respectively.1 Wrightoporiopsis is characterized by pileate, yellow to yellowish-brown basidiocarps, a dimitic hyphal system with generative hyphae bearing clamp connections, skeletal hyphae usually dextrinoid, basidiospores ellipsoid to subglobose, hyaline, finely asperulate, strongly amyloid, and causing a white rot.1
