Abstract

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