Stereum ostrea

Stereum ostrea, also called false turkey-tail and golden curtain crust, is a basidiomycete fungus in the genus Stereum. It is a plant pathogen and a wood decay fungus. The name ostrea, from the word 'oyster', describes its shape. With concentric circles of many colors, it highly resembles Trametes versicolor, turkey-tail, and is thus called the 'false turkey-tail'. The stemless fruiting body is shell-like and grows 1–7 cm (0.39–2.76 in) high. It is tough and inedible. It grows on tree bark. This fungus is native to the island of Java, Indonesia and has been misapplied to the North American Stereum species Stereum fasciatum, Stereum lobatum, and Stereum subtomentosum.
