Multicolor Gill Polypore
Semicircular, tough, hairy, multicolored, zoned bracket fungus with white, leathery, gill-like tubes beneath. Grows on dead deciduous wood. July–November. Cap semicircular; with concentric orange and brown zones, although sometimes white, cream, grayish or brownish; texture tough, hairy; often greenish because of algae growing in the hairs. Underside white, with leathery, gill-like tubes that are radially arranged, forked, and fused. Stalk not present. Spore print white. Spores magnified are cylindrical, smooth, colorless.
Lookalikes: Turkey tail (Trametes versicolor) doesn’t have a gill-like underside. False turkey tail (Stereum ostrea) has a smooth underside.
