Turkey Tail

Turkey tail (Trametes versicolor) is a common bracket fungus that grows in overlapping, fan-shaped layers on dead wood. Its thin caps are striped with rings of brown, tan, rust, blue-gray and cream, much like the spread tail feathers of a wild turkey. The species name versicolor simply means "of several colors."

Where to find it

Turkey tail is one of the most widespread mushrooms on Earth. It grows on fallen logs, stumps and branches of hardwoods, and sometimes conifers, in forests on every continent except Antarctica. You can spot it year-round in many climates. It plays an important ecological role as a decomposer, breaking down lignin and cellulose so nutrients return to the soil.

How to identify it

• Top: velvety, with sharply contrasting color bands.
• Underside: white to pale cream with tiny pores, not gills. This is the key feature that separates it from look-alikes such as false turkey tail (Stereum), which has a smooth underside.
• Texture: thin, flexible and leathery, too tough to eat.

Traditional use and research

Because it is too chewy to cook with, turkey tail has traditionally been dried and simmered into tea, a simple form of hot-water extraction. In China it is known as yun zhi ("cloud mushroom") and in Japan as kawaratake. Two protein-bound polysaccharides from turkey tail, known as PSK and PSP, have been the subject of extensive research in Japan and China, alongside its beta-glucans. Research continues, and outcomes vary with preparation.

Turkey tail in functional blends

Turkey tail is a frequent member of multi-species mushroom blends because its mild, slightly earthy taste is easy to balance with fruit or cocoa. It is a good example of the kind of traditional fungus that inspires the functional mushroom category.
