Two new species of Entoloma subg. Cyanula sect. Asprella (Entolomataceae, Agaricales) from subtropical regions of China

Two new species of Entoloma subg. Cyanula, <i>E. qingluan</i> and <i>E. zilin</i>, are described from subtropical regions of China based on morphological and phylogenetic evidence. <i>E. qingluan</i> is characterized by blue basidiomata, paler greyish-blue lamellae with a poliopus-type lamella edge, and pileipellis cells containing dark brown vacuolar pigments. <i>E. zilin</i> 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.
