The Turkey Tail mushroom (trametes versicolor), also known as the Polychrome Trametes, is a medicinal mushroom primarily found in the Northern Hemisphere. Its shape has been likened to a turkey's tail in the Western world, while in Asia it resembles a mushroom swirling like clouds. It has a long history in Chinese medicine due to its beneficial properties related to spirit and vital energy (Chi), as well as significant use in modern Japanese medicine.
