Paxillus involutus is a medium to large species characterized by a yellowish brown to olive brown or reddish brown cap that often is coated with soft matted hairs at first. The species epithet comes from the persistently inrolled cap margin. The gills are decurrent, yellowish to yellowish brown, and the stipe is similar in color to the cap.
