AI-generated description

Diplomitoporus flavescens is a species of fungus in the family Polyporaceae. It is a wood-decaying fungus that grows on coniferous trees, particularly spruce and fir. In St. Petersburg, Leningrad Oblast, and north-western Russia, Diplomitoporus flavescens has been found to be relatively rare, typically fruiting on dead or dying trees in old-growth forests. The fungus produces annual, effused-reflexed to pileate basidiocarps with a yellowish to golden-brown pore surface and a white to cream-colored context. It is considered a red-listed species in the region due to habitat loss and degradation.
