Red belt conk

Cap is hoof-shaped or triangular, hard and tough texture, up to 30–40 x 25 x 10 cm. Its 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. The pore surface is pale yellow to leather-brown, 3–4 pores per mm. It grows as thick shelves on live and dead coniferous or (less common) deciduous trees.[2]

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. The pores are whitish when young and become somewhat brownish in age.[3] This mushroom is inedible due to its woody texture, but it is useful as tinder.-Wikipedia
