Bassenthwaite Lichen

[black]

I photographed a few lichens whilst at Bassenthwaite, Cumbria at the weekend. Can anyone assist in teir ID please.

I thought that the first photo might be Ramalina farinacea or Evernia prunastri


The second lichen was growing on a rock close to the shore, I've no idea


From AlanS' comments on a similar looking lichen that Tormentil recently photographed, I expect the third is Parmelia sulcata

[poschiavanus]

I would agree with the first, it looks more like the Ramalina to me, but in practice I'd like to get close with a hand lens and really make sure that the two sides of the thallus are the same colour to exclude Evernia pruniastri.

Just above the lower of the two specimens of 'twiggy' lichens is a foliose one which really looks like Parmelia sulcata. On that basis I don't think that the third is P. sulcata. It has a much yellowish tinge, suggesting the presence of usnic acid, and a rather wrinkled appearance. I would suggest something more like Flavoparmelia caperata.

I still find lichens on trees and stones hard enough, and have done no lichenising on sea-shores so can't help with No. 2. Hopefully, AlanS will be along to offer some much more expert advice.
