AI-generated description

Schizopora paradoxa is a species of fungus that belongs to the family Schizoporaceae. It is a wood-decaying fungus that grows on dead trees, particularly on coniferous species. In St. Petersburg and Leningrad Oblast, it has been found on various substrates, including pine, spruce, and fir. The fungus is also widespread in north-western Russia, where it can be found in forests and woodland areas, often growing on decaying logs and stumps.
