Fomitiporia robusta is a species of fungus that belongs to the family Hymenochaetaceae. In St. Petersburg, Leningrad Oblast, and north-western Russia, it has been found growing on various tree species, including deciduous and coniferous trees. The fungus forms perennial, woody, and bracket-like or resupinate basidiocarps that are typically 5-20 cm wide and 2-10 cm thick. It causes brown rot in infected trees, particularly in birch, aspen, and alder. Fomitiporia robusta is widely distributed in the region, with records from urban parks, forests, and along rivers, indicating its adaptability to different environments.
