Fomitopsis pinicola
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. This mushroom is inedible due to its woody texture, but it is useful as tinder.
Redwood forest. Big leaf maple trunk. The species is common throughout the temperate Northern hemisphere.
An alternative binomial name is Fomes pinicola.
