Neoboletus luridiformis
Neoboletus luridiformis, known until 2014 as Boletus luridiformis, is a fungus of the bolete family, all of which produce mushrooms with tubes and pores beneath their caps. It is found in Northern Europe and North America, and is commonly known as the dotted stem bolete. Although edible when cooked, it can cause gastric upset when raw and can be confused where the two species coincide with the poisonous Rubroboletus satanas, which has a paler cap.
