Boletus pinophilus, also known as Pinewood King Bolete, is a large bolete with a dark brown cap, cream pores, reddish-brown netted, bulbous stem, commonly known as the pine bolete or pinewood king bolete. 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 colour beneath the cuticle, unchanging, thick, fairly firm. Pores
white then cream-coloured, becoming olivaceous-brown with age, circular and small. Spores
pallid olivaceous-yellow colored. Stem
thick and egg pr pear-shaped when young. The network pattern is dark brown at the bottom and gets lighter towards the cap. Flesh white, unchanging and fairly firm. The mushroom has no ring.
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.
