Extract from Wikipedia article: Xerocomellus chrysenteron, formerly known as Boletus chrysenteron or Xerocomus chrysenteron, is a small, edible, wild mushroom in the family Boletaceae. These mushrooms have tubes and pores instead of gills beneath their caps. It is commonly known as the red cracking bolete.
Xerocomellus chrysenteron is a species of bolete fungus that typically grows 3-8 cm in diameter, with a reddish-brown to dark brown cap and yellow to olive-green pores. In St. Petersburg and Leningrad Oblast, it is commonly found in coniferous and mixed forests, often associated with spruce and pine trees. In north-western Russia, the fungus fruits from July to October, preferring moist, acidic soils with abundant leaf litter and woody debris. It is considered a widespread and relatively common species in the region.

The mushrooms were found on lawns and trails, such as Lenin Trail near Dibuny. They were observed during summer months, from July to September, with specific sightings on July 20, 2016, September 6, 2018, and multiple times in July 2024. The underside of the mushroom was also observed, and spores were collected and examined in KOH, providing further identification details.

The observations suggest Xerocomellus chrysenteron is a widespread species in north-western Russia, particularly in urban and natural areas around Saint Petersburg.
