A common, shelf-like fungus that grows on dead or decaying hardwood. Its thin, fan-shaped caps display concentric bands of brown, tan, white, and sometimes blue or green, resembling a turkey’s tail. The surface is velvety or slightly hairy, while the underside has tiny pores instead of gills. Inedible but not toxic, it is valued in traditional medicine and plays an important role in breaking down wood in forest ecosystems.
