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 annexed 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. The principal purpose of this monograph by Largent is to provide original descriptions and key to aid in the identification of fifty-eight species, eighteen varieties and ten forms of Leptonia that the author identified from the West Coast of the USA. From the book collection of Nancy Jane Weber, inscribed to her by her father, Alexander H. Smith on the front endpaper.
