Extract from Wikipedia article: Aurantiporus fissilis is a species of poroid fungus in the family Polyporaceae. It is a plant pathogen. Although known primarily as a central and northern European species, it was recorded from Taiwan in 2016.
Aurantiporus fissilis is a rare polypore fungus that grows on deciduous trees, particularly willow and alder. In St. Petersburg and Leningrad Oblast, it has been found in parks and forests, often on Salix spp. and Alnus glutinosa. In north-western Russia, it is considered a regionally rare species, with records from the Murmansk, Arkhangelsk, and Vologda Oblasts, typically fruiting in late summer to early autumn.

The Greasy bracket polypore mushrooms (Aurantiporus fissilis)(?) on a mountain ash tree in Sosnovka Park. Saint Petersburg, Russia, July 16, 2017Svetlanovskiy pr., 51, Sankt-Peterburg, Russia, 194064Observations of Aurantiporus fissilis in Leningrad Oblast and north-western Russia reveal its presence in various environments. In Sosnovka Park, Saint Petersburg, the fungus was found at the base of a tree on July 16, 2017. Additionally, it was observed growing on a mountain ash tree in the same park on the same date. The sightings suggest that Aurantiporus fissilis can thrive on different types of substrates, including tree trunks and possibly other deciduous trees like mountain ash. The fungus appears to be active during the summer months, with observations recorded in mid-July. These findings contribute to our understanding of the distribution and habitat preferences of Aurantiporus fissilis in north-western Russia. Further research is needed to fully elucidate its ecological role and behavior in this region. The sightings provide valuable insights into the fungus's growth patterns and substrate preferences.
