Phellinus igniarius

Phellinus igniarius (syn. Phellinus trivialis) is a   fungus of the family of Hymenochaetaceae. Like other members of the genus of Phellinus  it lives by saprotrophic nutrition, in which the lignin and cellulose of a host tree is degraded and is a cause of white rot. Common names are willow bracket and fire sponge
The fungus  forms perennial fruiting bodies   that rise as woody-hard, hoof or disc-shaped brackets from the bark of the infested living tree or dead log. The tree species is often willow but it may be commonly found on birch and alder and other broad leafed trees. The top is covered with a dark, often cracked crust, a stem is present only in its infancy. Unlike most fungi it has a hard woody consistency and may persist for many years, building a new surface layer each year. It was prized as kindling material.
