Extract from Wikipedia article: Trichaptum biforme is a species of poroid fungus in the order Hymenochaetales. It is a saprobe that decomposes hardwood stumps and logs.
Trichaptum biforme is a species of fungus that grows on dead wood, typically coniferous trees. In St. Petersburg, Leningrad Oblast, and north-western Russia, it has been found to fruit from June to October, often in groups or clusters, on stumps, logs, and fallen branches of spruce, pine, and fir. The fungus has a semicircular to kidney-shaped cap, 2-6 cm wide, with a wavy edge and a hairy, zonate upper surface, ranging in color from grayish-brown to dark brown. The underside is white to cream-colored with small, triangular pores. It is a relatively common species in the region, often occurring in moist, shaded areas with abundant coniferous debris.

Purple toothed polypore mushrooms (Trichaptum biforme) on a fallen birch near Dibuny, north-west from Saint Petersburg, Russia, May 5, 2021Observations of Trichaptum biforme in Leningrad Oblast and north-western Russia show that the fungus is commonly found on birch logs and trees. It was observed in various locations, including Lisiy Nos, Sosnovka Park, and Dibuny, from August to May, suggesting a wide range of fruiting times.
