Hairy curtain crust fungus (Stereum hirsutum) is common in Britain and Ireland, and is widely distributed throughout the world. Visible year-round, it is frequently mistaken for turkeytail fungus (Trametes versicolor) although it can be distinguished by its hairy upper surfaces. This species is particularly associated with the rotting trunks and branches of oak and beech.
