Phellinus contiguus
Identifications:

Phillinus contiguous is a typical white rot.

Course fibrousy appearance, usually in severely decayed timbers. Take care to examine the wood as a whole, where the fibrous nature will then be apparent.

Mycelium about the colour of chamois leather (tawny) and roughly looks like it; often in sets if present.

Small 'tufts' tawny coloured growth within cracks in rotted wood, break apart the wood and look for this.

Fruiting body is brown and 'woody'. Lots of small pores; fruiting body moulds itself to the shape of the wood surface.
