Extract from Wikipedia article: Suillus grevillei (commonly known as Greville's bolete and larch bolete) is a mycorrhizal mushroom with a tight, brilliantly coloured cap, shiny and wet looking with its mucous slime layer. The hymenium easily separates from the flesh of the cap, with a central stalk that is quite slender. The species has a ring or a tight-fitting annular zone.
Suillus grevillei is a boletoid fungus that grows in association with larch trees. In St. Petersburg, Leningrad Oblast, and north-western Russia, it typically fruits from July to October, often in moist, sandy soils under Larix sibirica or Larix decidua. The cap is 4-10 cm wide, orange-brown to reddish-brown, and viscid when wet. The pore surface is yellow, becoming olive-brown with age. It is a common species in the region's coniferous forests, particularly in areas with larch dominance.
