Common names: Multicolor Gill Polypore, Gilled Polypore.
Extract from Wikipedia article: Trametes betulina (formerly Lenzites betulina), sometimes known by common names gilled polypore, birch mazegill or multicolor gill polypore, is a species of fungus.
Lenzites betulina is a bracket fungus that grows on deciduous trees, particularly birch, beech, and maple. In East and Central Texas, it typically fruits from spring to fall, forming semicircular to circular brackets with a zonate upper surface and gills underneath. The caps are 2-8 cm wide, with a rough, hairy texture and a range of colors from gray to brown to tan. It is commonly found on stumps, logs, and living trees in wooded areas, including those along streams and rivers.
