Extract from Wikipedia article: 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. The fungus produces cup-shaped fruit bodies that typically grow in clusters on branches and exposed portions of buried wood throughout eastern and Midwest North America and in Malaysia. The fruit bodies have the texture of tough, gelatinous rubber, and have a rough, blackish-brown, felt-like outer surface and a smooth reddish-brown inner surface. Although generally considered inedible by North American mushroom field guides, it is commonly consumed in Malaysia. The fungus produces several interesting natural products.
