Horse's Hoof Polypore

Description:

F. fomentarius can vary in color from a very light grey to almost black. Loos like a horse's hoof. Fomes fomentarius is a stem decay plant pathogen. The species' mycelium penetrates the wood of trees through damaged bark or broken branches, causing rot in the host. It can grow on the bark wound, or even directly onto the bark of older or dead trees. The decayed wood shows black lines in the lightly coloured decayed areas; these are known as pseudosclerotic layers or demarcation lines
