Tree Lichen - id help please

Trees are few and far between on South Uist, so an old plantation is usually a good source of material.
We think this may be Hypotrachyna britannica.
As novices, we would appreciate comments and/or correction.

thank you

Hi Chris - this one looks like it could be Parmotrema perlatum

Hi Jenny
Many thanks for pointing me in the right direction. I see you have a nice image of it on your website.

I agree with Jenny that this is Parmotrema perlatum.

My own site shows some of the variation in this species.

Sometime I'll add the rest of the British Hypotrachyna species to my site too - they are in the pipeline but the metaphorical pipeline is becoming ever more clogged!

H. britannica, in my limited experience, is a smaller and in some ways rather uninteresting-looking species, usually on rocks.
