Extract from Wikipedia article: Boletopsis grisea is a species of fungus in the family Bankeraceae. The fruit bodies are gray, fleshy polypores that grow on the ground in a mycorrhizal association with Scots pine (Pinus sylvestris). It is found in Asia, North America, and Europe.
Boletopsis grisea is a species of fungus that belongs to the family Bankeraceae. It is characterized by its greyish-brown to dark brown cap, which can reach up to 10 cm in diameter, and its white to pale yellow pores. In St. Petersburg, Leningrad Oblast, and north-western Russia, Boletopsis grisea has been found growing in coniferous and mixed forests, typically on sandy or clay soils. It fruits from late summer to early autumn, often in association with spruce, pine, or birch trees. The fungus is considered rare in the region, but can be locally common in suitable habitats.
Observations of Boletopsis grisea in Leningrad Oblast and north-western Russia reveal its presence in various locations. The fungus was found in Petiayarvi, 50 miles north of Saint Petersburg, on August 31, 2013. Subsequent sightings occurred in Orekhovo, near Dibuny, and Toksovo, with multiple observations in the same areas over the years, including August 17, 2016, September 7, 2016, September 9, 2016, August 30, 2018, and September 5, 2018. The mushrooms were often found in moss or on old sand dunes overgrown by pine forests, such as in Sestroretskoye Swamp near Saint Petersburg, where they were observed on August 11, 2024. Cross-sections of the mushrooms were also examined, providing further insight into their structure. The consistent presence of Boletopsis grisea in these areas suggests it is a relatively common species in the region.
