Abstract
Two new species of Entoloma subg. Cyanula, E. qingluan and E. zilin, are described from subtropical regions of China based on morphological and phylogenetic evidence. E. qingluan is characterized by blue basidiomata, paler greyish-blue lamellae with a poliopus-type lamella edge, and pileipellis cells containing dark brown vacuolar pigments. E. zilin features a greyish-magenta scaly pileus with a bluish lamella edge adjacent to the stipe, a blue stipe, fertile lamella edges, and predominantly 2-spored basidia. Both species are assigned to subg. Cyanula sect. Asprella based on their striate or squamulose pileus, blue stipe, and fertile or poliopus-type lamella edge. Detailed descriptions, color photos, and scanning electron micrographs of spores are presented.
