Cap hoof-shaped or triangular, hard and tough texture, up to 30-40 x 25 x 10 cm. Surface is more or less smooth, at first orange-yellow with a white margin, later dark reddish to brown and then frequently with orange margin. Pore surface pale yellow to leather-brown, 3-4 pores per mm. Grows on live and dead coniferous or (less common) deciduous trees.
The fruiting body of Fomitopsis pinicola is called the conk. It is a woody, pileate fruiting body with pores lined with basidia on its underside. As in other polypores, the fruiting body is perennial with a new layer of pores produced each year on the bottom of the old pores.
