Found this on Veteran Oak.Id please.

I found this growing about six inches from the ground on a Mature Oak Tree.The Crown of the Tree was sparcer than normal.

 

Can anyone tell me what the Fungus is?

 

The fruiting body is about 1.5 inches across and was bright yellow similar to a Egg Yolk in colour when I found it.

Almost certainly a mycorhizal bolete. Odd to be on the stem though. I see moss, is the base of the tree often damp? May be that the mycelium from the soil has found a route up the bark furrows/under loose bark...

The base of the Tree is often Damp.Everything is often damp in Western Norway:001_smile:

 

When I pulled it off,a chunk of the Bark came too.

Good chance then that something else has caused bark death and decay. This fungi, likely in association with the trees own roots, is recycling the nutrients present in the decaying bark and detritus; feeding the tree with its own rotting body, nice

Thankyou for your help.

No problem. I may be wrong though! Best wait for Mr Humphries or Croft to pop their head in...
