Extract from Wikipedia article: Suillellus luridus (formerly Boletus luridus), commonly known as the lurid bolete, is a fungus of the bolete family, found in deciduous woodlands on chalky soils in Asia, Europe, and eastern North America. Fruit bodies appear in summer and autumn and may be abundant. It is a solid bolete with an olive-brown cap up to 20 cm (8 in) in diameter, with small red pores on the underside. The stout ochre stem reaches 8–14 cm (3–6 in) high and 1–3 cm (0.4–1.2 in) wide, and is patterned with a red mesh-work. Like several other red-pored boletes, it stains blue when bruised or cut. Though edible when cooked, it can cause gastric upset when eaten raw and can be confused with the poisonous Boletus satanas, though the latter species has a pale cap; as a result, some guidebooks recommend avoiding consumption altogether. When consumed with alcohol, Suillellus luridus has been implicated in causing adverse reactions similar to those caused by the compound coprine, though laboratory testing has not revealed any evidence of coprine in the mushroom.
Suillellus luridus is a species of bolete fungus characterized by its dark brown to black cap, yellow to olive pores, and stout stem. In St. Petersburg and Leningrad Oblast, it typically fruits in summer and autumn in coniferous and mixed forests, often associated with spruce and pine trees. In north-western Russia, the species is widely distributed, commonly found in similar habitats, including mossy spruce forests and heathlands, where it grows solitary or in small groups, preferring acidic soils rich in humus.
