AI-generated description
Phellinus igniarius is a perennial, bracket-shaped fungus that grows on deciduous trees, particularly willow, alder, and birch. In St. Petersburg, Leningrad Oblast, and north-western Russia, it is commonly found in urban parks, forests, and along rivers. The fungus produces fruiting bodies 3-10 cm wide, with a rusty-brown to dark brown cap and yellowish-brown pores. It is a saprotroph, contributing to wood decay, and can also form parasitic relationships with living trees. Specimens have been collected in the region from May to October, with peak fruiting typically occurring in August and September.
