Fomitopsis ochracea is a polypore fungus found in North America.[1] It was isolated from Albertan forests, and can be found in British Columbia.[1] It has been isolated as far East as Newfoundland, but prefers Northern climates.[2] It can be isolated throughout the Appalachian range, as far down as Georgia.[2] It is a detritivore on both hardwood trees and conifers, causing a brown cubical rot.[1] It is a member of the genus Fomitopsis, a common group of perennial fungi.
Description
Fomitopsis ochracea is a fungus that may be shaped like a hoof or flattened in a fan-like manner.[1] It can grow quite large, up to 20 cm in width and 7 cm thick.[1] The top surface of the fungus is smooth and may be coloured white, grey, brown, or black, with parallel lines.[1] It can have black or brown spotting on the surface.[2] The underside is a creamy-white, with even, round pores.[1] It can also become orange with age.[2] If broken open, the context will be woody with a creamy-white colour and no bands.[1] There is no visible bruising upon breaking open the body.[1] There are about 5-6 pores present per millimetre.[1] It can have a faint sweet odour.[2]
Historically, this fungus has been misidentified as F. pinicola. When both species are immature, they can look very similar, but can be distinguished by lighting a match next to the surface of the fungus.[1] F. pinicola will boil and melt in heat, while F. ochracea will not.[1] If this test is not available, a simple bruise test can distinguish the two. F. pinicola will bruise a yellow colour when broken open, while F. ochracea will not bruise at all.
