The species is recognized by the corrugated, viscid pileus, the yellow orange colors of the pileus and stipe, and lamellae with a lilac tint, especially when young. The base of the stipe has a marginate bulb. The spores are coarsely verrucose. Originally described from New York State, C. corrugatus is another of the North Temperate elements to migrate with oaks to the Neotropics. So far, known only from one site in Costa Rica near Empalme (Jardín) in the Talamancas. On rare occasions, a gastroid form has appeared in the Savegre river valley.
