Lichen ?

I came across something similar to this on an old hazel tree. I thought it was a fungus but was advised by an OU tutor that it could be a lichen. I have viewed several images and decided that my observation was a collema of some sort, although I haven't had that confirmed.

This one resembles my own observation, which AlanS identified:


Yours (http://www.ispot.org.uk/node/238625) doesn't look anything like mine, but I can see it does resemble the pruinose part of ex-royal's observation. I suppose there's a chance that all 3 are the same species, with different degrees of degradation.
