The devil's urn (Urnula craterium) is a black or brown cup-shaped fungus. The species' tough, cracked outer layer and dark coloration may give it a scorched appearance. Devil's urns tend to grow in clusters and are usually found adorning fallen branches and rotting logs. Though the species is not edible itself, gatherers keep an eye out for it, as it usually fruits at about the same time as morels.
