Extract from Wikipedia article: Tylopilus felleus, commonly known as the bitter bolete or the bitter tylopilus, is a fungus of the bolete family. Its distribution includes east Asia, Europe, and eastern North America, extending south into Mexico and Central America. A mycorrhizal species, it grows in deciduous and coniferous woodland, often fruiting under beech and oak. Its fruit bodies have convex to flat caps that are some shade of brown, buff, or tan, and typically measure up to 15 cm (6 in) in diameter. The pore surface is initially white before turning pinkish with age. Like most boletes it lacks a ring, and it may be distinguished from Boletus edulis and other similar species by its unusual pink pores and the prominent dark brown netlike pattern on its stalk.
Tylopilus felleus is a bolete fungus with a brown to reddish-brown cap and white to yellowish pores. It grows in association with coniferous trees, particularly pine and spruce. In St. Petersburg, Leningrad Oblast, and north-western Russia, Tylopilus felleus is commonly found in moss-covered forests, heathlands, and sandy soils, typically from July to October. The fungus is widespread in the region, with frequent occurrences in areas with acidic soils and moderate humidity.
