I have to say that learning even a little about lichens has been an interesting experience. There was such an assortment at Glenelg that I probably missed many more than I photographed. I don't believe that any I've included are particularly rare and my attempts to indentify them were neither sophisticated nor very scientific; I tried my best to navigate a way through a key and compared my photographs with those in books or on the websites of experienced lichenologists. As ever, I am happy to hear from anyone who might identify them differently.
Throughout the region, trees were found covered in these Unsea filipendula, often hanging in lengths of up to five feet as in the right-hand picture:
The following is Peltigera membranacea, olive green above (top) with cream undersides (below) ...

These are two more of the Cladonia family, both no more than 20mm tall, the first Cladonia coniocraea, the second Cladonia squamosa ...
... while the following are two Ochrolechias, the first Ochrolechia parella, the second Ochrolechia tartarea ...
This last lichen has been the hardest to identify. The Scottish Lichen Group have told me that it is Lecidea lapicida ...
Finally, this fern. I should probably have been more rigorous, conducting an intimate examination, and I'm sorry I didn't. From my limited reference sources describing ferns I would say that it looks like a spleenwort, but I can't be sure so hopefully someone will tell me ...
... My thanks to Phil Gates, who has kindly suggested Polypodium, which is common throughout Britain on wall tops, as in this case, trees and rocks. The fronds are 10-40cm long, flat and oblong, with lobes more or less equal in size. Because of the location, this example would, I think, be Common Polypody (Polypodium vulgare)
