Extract from Wikipedia article: Rhodofomes roseus is a species of pink polypore found in western North America and Europe. This is a close relative of another species of pink conk, the rosy conk (Rhodofomes cajanderi). While R. cajanderi is a plant pathogen, R. rosea is a detritivore.
AI-generated description
Fomitopsis rosea is a species of fungus that belongs to the family Fomitopsidaceae. It is characterized by its pink to reddish-brown cap and white to yellowish pores. In St. Petersburg and Leningrad Oblast, Fomitopsis rosea has been found growing on deciduous trees, particularly on birch and aspen. In north-western Russia, it is considered a rare species, typically fruiting in late summer to early autumn. Records of the fungus have been reported from the Karelian Isthmus and the Vepsian Upland, where it inhabits old-growth forests with rich soil and high humidity.

AI-generated summary of observations
In Leningrad Oblast and north-western Russia, observations of Fomitopsis rosea revealed the fungus grows on fallen spruces in dark forests. The mushrooms have a dark upper surface and pink underside with a fibrous texture inside. They were found near Saint Petersburg, between Lisiy Nos and Morskaya, and in a forest near Okhta River in Toksovo. The pore surface is pink, and some specimens showed guttation, exuding water droplets. Resupinate forms of the fungus were also observed on the underside of spruce logs, with secretion of water droplets on the pore surface. The mushrooms were abundant in the area, with multiple observations recorded on May 14 and 16, 2021. Overall, Fomitopsis rosea appears to thrive in the region's forest ecosystems, particularly on fallen coniferous trees.
