a hymenomycetous gill fungus. The cap, which is 3 to 10 cm in diameter, is convex in the young fungus and later becomes indented or even funnelform. It has a broad tubercle in the middle and an unevenly wavy margin. Its color is white, off-white, or yellowish. The gills, which extend to the stipe below, are white at first and later turn a dirty pink. The short, white stipe thickens toward the top. The meat is white and has an odor of fresh flour. Clitopilus prunulus grows in deciduous and mixed forests and in parks. It is particularly common in the western and southern regions of the European USSR. The mushroom is edible.
