I just came on to start a thread about a similar fungi I found at the weekend.
I'll post what I was going to put here instead of starting a new one:
--------------------------
The parents were visiting at the weekend so went out hunting Ancient Trees with the Old Man.
While we were out we spotted this fungi.
At first I thought someone had sprayed expanding foam on the tree as it's very soft and is slightly 'oozing' down the tree.
It doesn't show in the picture but when cut open the flesh is a pale pink (and yes, it looks like a monsters head to me too!)
It has no smell, nor any taste (I didn't taste it but my Dad is a keen Mycologist and old so will take the risk. )
So, anyone know what it is? We presume it's the young form of a fungi but it is like nothing we knew.
