Extract from Wikipedia article: Phellinus ferruginosus is a plant pathogen. It is inedible.
Phellinus ferruginosus is a perennial, resupinate to effused-reflexed fungus that grows on deciduous trees, particularly willow, alder, and birch. In St. Petersburg and Leningrad Oblast, it has been found in urban parks and forests, often on Salix and Alnus species. In north-western Russia, it is widely distributed, typically growing on living or dead trunks and branches of deciduous trees, especially in moist, shaded areas. The fungus produces distinctive reddish-brown to ferruginous fruiting bodies with a rough, velvety surface and a white to cream-colored pore surface.
