AI-generated description

Porodaedalea laricis is a crust fungus that grows on the bark of living larch trees. In St. Petersburg and Leningrad Oblast, it has been found to be relatively rare, typically fruiting in summer and early autumn. In north-western Russia, the species has been recorded in various locations, including old-growth forests and urban parks, where it tends to thrive on mature larch trees with rough bark. The fungus forms effused-reflexed basidiocarps with a greyish-brown to brownish-grey upper surface and a smooth, cream-colored underside, producing white to yellowish spores.
