| | | Unidentified Lichen from Lindrick Dale
Hello all
We found this Lichen (Possibly on Ash) at Lindrick Dale 12th February 2011 on a fungi Foray. 
Closeup: 
Any help with identification, comments much appreciated

Hi John,
Very water-soaked so not looking quite typical, but this is good material of Physcia aipolia. Usually has abundant apothecia, and the surfaces of the lobes have abundant white markings (pseudocyphellae), though not so clear when there is a film of water over the colony.
Widespread and often common on twigs of trees with a moderately high bark pH - such as Ash!
For more typical appearance when dryer, see the previous post in this forum, "lichen on fence rail".
btw, Physcia aipolia can sometimes give you extra 'points' on a fungus foray: Syzygospora physciacearum (images of British lichenicolous fungi) Marchandiomyces corallinus (images of British lichenicolous fungi)

Alan | Many thanks Alan, much appreciated! More points are always welcome too!!
Looking at the 'more' typical images I can clearly see the differences.
