AI-generated description

Tremella encephala is a jelly fungus that grows on decaying wood, typically appearing as a brain-like or lobed gelatinous mass. In St. Petersburg, Leningrad Oblast, and north-western Russia, it has been found in coniferous and mixed forests, often on fallen trunks or stumps of spruce, fir, and pine trees. It is commonly associated with fungi such as Peniophora and Stereum, and can be found fruiting from summer to autumn, particularly after rainy periods. The fungus is widely distributed in the region, including in urban parks and forests near St. Petersburg.
