Common Names: Hairy rubber cup, rubber cup, rufous rubber cup
Sub-category: Cup Fungus
The fruit bodies are initially closed and roughly spherical to top-shaped, and resemble minute puffballs. They later open in the shape of a shallow cup, and reach diameters of 15 to 35 mm wide. The cup margin is curved inwards and irregularly toothed; the teeth are a lighter color than the hymenium. The interior surface of the cup, which bears the spore-bearing surface (the hymenium) is reddish-brown to orange-brown. The exterior surface is blackish-brown, and covered with tiny hairs that give it a felt-like or hairy texture. The flesh of the fruit body is grayish, translucent, gelatinous and rubbery. The fungus sometimes has a short stem that is up to 10 mm long by 5 mm wide, but it may be missing in some specimens. Dried fruit bodies become leathery and wrinkled.
Typically grow in clusters on branches and exposed portions of buried wood.
