AI-generated description

Inocutis rheades is a species of polypore fungus that grows on deciduous trees, particularly willow and alder. In St. Petersburg and Leningrad Oblast, it has been found in urban parks and forests, typically on Salix and Alnus species. In north-western Russia, it is widely distributed in temperate and subboreal forests, often associated with moist environments and rich soils.

AI-generated summary of observations

Observations of the fungus Inocutis rheades in Leningrad Oblast and north-western Russia reveal its presence in various locations. On August 12, 2017, it was found in Kannelyarvi, 45 miles north of Saint Petersburg, where its bracket shape and porous underside were noted. Similar sightings occurred on August 20, 2017, near Dibuny, northwest of Saint Petersburg, with the fungus growing on a fallen spruce tree. The fungus's ability to grow on decaying wood is evident from these observations. Its distribution in the region suggests it may be a common species in Leningrad Oblast and north-western Russia, particularly in areas with abundant coniferous trees. The observed specimens exhibited typical characteristics of Inocutis rheades, including its distinctive bracket shape and porous spore-bearing surface.
