Extract from Wikipedia article: Polyporus umbellatus is a rare, edible species of mushroom, found growing on roots of old beeches or oak (e.g.). It is also called lumpy bracket and umbrella polypore.
Polyporus umbellatus is a perennial fungus that grows in clusters, with multiple caps attached to a central stalk. In St. Petersburg, Leningrad Oblast, and north-western Russia, it typically fruits from July to October, often on stumps, logs, and living trees, particularly birch and aspen. The fungus has been found in various habitats, including forests, parks, and along rivers, with a preference for moist, rich soils. Its caps are 2-8 cm in diameter, umbrella-shaped, and grayish-brown to dark brown in color, while the pores on the underside are white to light yellow.
Observations of Polyporus umbellatus in Leningrad Oblast and north-western Russia show the fungus grows in various locations. It was found on an old railroad path near Kuzmolovo, north of Saint Petersburg, and in the area of Rappolovo near Toksovo. The mushroom also appeared near Lisiy Nos, west of Saint Petersburg. The observations were made over several years, from 2017 to 2024, indicating a consistent presence in the region. The fungus was observed growing individually and in groups, with multiple caps forming in some cases. The underside of the mushrooms was also documented, showing the characteristic pores of the species. Overall, Polyporus umbellatus appears to be widely distributed in the region, thriving in various environments. Its growth patterns and habitats were consistently observed across different locations and years.
