Turkey tail (Trametes versicolor) is a bracket fungus in the Polyporaceae family found across North America, Europe, and Asia. It grows in fan-shaped tiers on dead or decaying wood and shows concentric bands of brown, tan, gray, and cream. The fruiting body is the part used in traditional preparations.
Because turkey tail is tough and leathery, it is usually prepared as a decoction, powder, or extract rather than eaten as a table mushroom. It has a long history in East Asian mushroom traditions and is also widely used in modern wellness products.
