Extract from Wikipedia article: Stereum sanguinolentum is a species of fungus in the Stereaceae family. A plant pathogen, it causes red heart rot, a red discoloration on conifers, particularly spruces or Douglas-firs. Fruit bodies are produced on dead wood, or sometimes on dead branches of living trees. They are a thin leathery crust of the wood surface. Fresh fruit bodies will bleed a red-colored juice if injured, reflected in the common names bleeding Stereum or the bleeding conifer parchment. It can be the host of the parasitic jelly fungus Tremella encephala.
Stereum sanguinolentum is a species of crust fungus that grows on dead wood, characterized by its reddish-brown to violet-brown color and wavy to lobed margin. In St. Petersburg and Leningrad Oblast, it has been found on various deciduous tree species, including birch, alder, and willow. The fungus is also widely distributed in north-western Russia, where it typically fruits from July to October, often forming large clusters on logs and stumps in moist, shaded areas.
