Spuing
Fomes fomentarius
Tinder or horse's hoof fungus

These are the largest examples I've encountered of this fungus, the lower ones were much bigger than dinner plates (about 50cm across).

The first English common name comes from their use as natural fire lighters (nothing to do with a dating website). The fungus also grows in a shape resembling a horse's hoof.

This fungus was growing on a very large, long-dead beech tree.
