Pycnoporellus fulgens is a rare, brightly colored fungus found in northern regions. In St. Petersburg, Leningrad Oblast, and north-western Russia, it typically grows on coniferous trees, particularly spruce and fir, from July to October. The fungus has a bright orange to yellow-orange cap, 2-6 cm in diameter, with a velvety to woolly surface and white to yellow pores underneath. It is considered a vulnerable species due to habitat loss and limited distribution. Records of Pycnoporellus fulgens in the region are sparse, but it has been spotted in forests and parks around St. Petersburg, including the Karelian Isthmus and the Valdai Hills.
