AI-generated description

Peniophora incarnata is a crust fungus that grows on dead wood, characterized by its pink to reddish-brown resupinate fruiting body. In St. Petersburg and Leningrad Oblast, it has been found on various tree species, including birch, alder, and willow. In north-western Russia, it is widely distributed in temperate forests, particularly in areas with high humidity and abundant deciduous trees. The fungus is typically observed from summer to autumn, and its growth is often associated with decayed logs and stumps.

AI-generated summary of observations

Observations of the fungus Peniophora incarnata were made in Leningrad Oblast and north-western Russia between February 2017 and May 2021. The fungus was found on various trees, including those with dark bark, dry trees, and cut surfaces. Locations included Udelny Park, Sosnovka Park, and areas near Saint Petersburg such as Lisiy Nos, Dibuny-Pesochny, and Orekhovaya Gora Hill. In some cases, the fungus was parasitized by golden jelly fungus (Tremella mesenterica). The observations were made during different times of the year, with the earliest in February and the latest in May, suggesting that the fungus can be present throughout the spring season. The fungus was identified as Peniophora incarnata or suspected to be this species due to its characteristic rosy or salmon-colored crust.
