Tremella mesenterica

I found a nice example of Tremella mesenterica or Yellow Brain Fungus this morning, growing on the branch of an oak tree. I photographed it and thought it would make a good blip but as I was walking away I noticed that the other side of the branch had another jelly fungus - this is, I think, also Tremella mesenterica but in its rarer unpigmented form. I don't recall ever seeing this before and certainly not right next to the yellow form (you can just see a bit of the yellow one to the left hand side).
