Trametes versicolor – also known as Coriolus versicolor and Polyporus versicolor – is a common polypore mushroom found throughout the world. Meaning 'of several colours', versicolor reliably describes this fungus that displays different colors. For example, because its shape and multiple colors are similar to those of a wild turkey, T. versicolor is commonly called turkey tail.

Description and ecologyEdit
The top surface of the cap shows typical concentric zones of different colours. The flesh is 1–3 mm thick and has leathery texture. Older specimens, such as the one pictured, can have zones with green algae growing on them, thus appearing green. It commonly grows in tiled layers. The cap is rust-brown or darker brown, sometimes with blackish zones. The cap is flat, up to 8 × 5 x 0.5–1 cm in area. It is often triangular or round, with zones of fine hairs. The pore surface is whitish to light brown, pores round and with age twisted and labyrinthine. 3–8 pores per millimeter.
It may be eaten by caterpillars of the fungus moth Nemaxera betulinella and by maggots of the Platypezid fly Polyporivora picta. and the fungus gnat Mycetophila luctuosa, but is considered inedible to humans.
Trametes versicolor contains polysaccharides under basic research, including the protein-bound PSP and β-1,3 and β-1,4 glucans. The lipid fraction contains the lanostane-type tetracyclic triterpenoid sterol ergosta-7,22,dien-3β-ol as well as fungisterol and β-sitosterol.
Research and usesEdit
This mushroom, known as yun zhi [雲芝] in China, is used in traditional Chinese medicine; it is supposed to boost the immune system and have anticarcinogenic properties. Its polysaccharides are thought to be the effective constituents.
