Leptonia
Leptonia has been defined as a genus of small and medium sized pink-spored mushrooms that contains over 100 species. They are saprotrophic and most grow on the ground, but some are found on wood. The cap is thin and can be convex, plane, often depressed and usually has small scales. The gills are widely spaced, usually having adnexed to adnate attachment (rarely they can be a little decurrent) and the stalk is fragile. The spores are angular and are flesh colored to pink. Some "Leptonia" species have distinctive colors such as black, blue, green, yellow, and violet, but  even these are difficult to identify. Most modern taxonomic authorities do not recognize "Leptonia" as a genus in its own right, but only as a subgenus of "Entoloma". Little is known about the edibility of mushrooms of this group, and some are poisonous. Data produced by the molecular study by Moncalvo in 2002, has species of "Nolanea", "Leptonia" and "Inocephalus" interspersed with various "Entoloma" species in a broadly monophyletic entolomatoid group.
