It grows solitary or scattered on soil particularly with Scots pine in Britain. The mushroom prefers the poor, acidic, and sandy soils associated with coniferous forests.
deep red-brown or copper coloured. Stays convex for a while, but eventually flattens out. Often irregular in shape when mature. The surface is hard, dimpled and rough and sticky when damp. The flesh is white, tinged cap color beneath the cuticle, unchanging, thick, fairly firm. Pores
white then cream colored, becoming olivaceous-brown with age, circular and small. Spores
pallid olivaceous-yellow colored. Stem

The closely related Boletus edulis has brown color and grows with Pine. Tylopilus felleus is similar when young but tastes bitter and is thus inedible.
