Extract from Wikipedia article: Stereum hirsutum, also called false turkey tail, 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. Substrates for S. hirsutum include dead limbs and trunks of both hardwoods and conifers.
Stereum hirsutum is a crustose fungus that grows on decaying wood, characterized by its hairy, velvety upper surface and smooth, wavy lower surface. In St. Petersburg, Leningrad Oblast, and north-western Russia, it has been found to commonly inhabit deciduous and coniferous forests, typically growing on fallen branches, stumps, and logs of various tree species, including birch, aspen, and spruce. The fungus is widely distributed in the region, with frequent records from urban parks and natural reserves, where it plays a role in decomposing organic matter and contributing to nutrient cycling.
