Galiella rufa, commonly known as the rubber cup, the rufous rubber cup, or the hairy rubber cup, is a species of fungus in the family Sarcosomataceae. It produces cup-shaped fruit bodies with the texture of tough, gelatinous rubber, with a rough, blackish-brown, felt-like outer surface and a smooth reddish-brown inner surface.
Found throughout eastern and Midwest North America as well as in Malaysia, the fruit bodies typically grow in clusters on branches and exposed portions of buried wood. Although generally considered inedible by North American mushroom field guides, the species is commonly consumed in Malaysia. It also produces several natural products.
