Phellinus chrysoloma is a species of fungus that belongs to the family Hymenochaetaceae. It is a perennial, saprotrophic fungus that grows on dead wood, typically coniferous trees. In St. Petersburg, Leningrad Oblast, and north-western Russia, Phellinus chrysoloma has been found to be widely distributed, particularly in forests dominated by spruce, pine, and fir. The fungus produces fruiting bodies that are annual, sessile, and circular to semicircular, with a golden-brown to dark brown cap and a white to cream-colored pore surface. It is commonly found on stumps, logs, and dead branches of coniferous trees, where it plays a role in decomposing organic matter.
