Stereum hirsutum, commonly known as the false turkey tail,[1] hairy stereum,[2] or hairy curtain crust,[3] is a fungus typically forming multiple brackets on dead wood. It is also a plant pathogen infecting peach trees. S. hirsutum is in turn parasitised by certain other species such as the fungus Tremella aurantia.[4][5] Substrates for S. hirsutum include dead limbs and trunks of both hardwoods and conifers.[6]
