Trametes versicolor

Trametes versicolor – also known as Coriolus versicolor and Polyporus versicolor – is a common polypore mushroom found throughout the world. Meaning 'of several colors', 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 ecology

The top surface of the cap shows typical concentric zones of different colors. 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.
