Extract from Wikipedia article: Tapinella atrotomentosa, commonly known as the velvet roll-rim or velvet-footed pax, is a species of fungus in the family Tapinellaceae. Although it has gills, it is a member of the pored mushroom order Boletales. August Batsch described the species in 1783. It has been recorded from Asia, Central America, Europe and North America. Tough and inedible, it grows on tree stumps of conifers. The mushroom contains several compounds that act as deterrents to deter feeding by insects.
Tapinella atrotomentosa is a species of fungus that belongs to the family Tapinellaceae. It is characterized by its dark brown to black cap with white or pale yellowish pores underneath. In St. Petersburg and Leningrad Oblast, as well as in north-western Russia, T. atrotumentosa has been found growing on coniferous trees, particularly on spruce and fir stumps, logs, and roots. The fungus typically fruits from July to October, with a peak in August and September. It is considered a rare species in the region, but can be locally common in areas with abundant coniferous deadwood.
