is characterized by the following features: small, creamy, discoloring to brown basidiomes, umbonate pileus, cylindrical stipe with a fugacious fibrillose annulus, and ovoid, obovoid, subglobose cheilocystidia. The most distinctive feature is the appendiculate margin with relatively long veil remnants that resemble teeth. At least two other previously studied species are known to have a denticular pileus margin and small basidiomata:
