Punctelia

Aha! I thought it looked a bit different. The angular lobes and 'hammered' appearance still had me convinced though, so I assumed it was P. sulcata with a less developed network of lines, and also developing soralia. Thanks Jenny.

Punctelia?

Might I invite a collective rethink on this one? I'm still struggling to accept the consensus, especially in view of the lobe shape.

Yes, I am fairly sure you are right, Nigel. Looking at this again I don't see it as a Punctelia.

Phew!

I'll sleep easier now. This has lingered in my Favourites and has been puzzling/bugging me for over a year, but I haven't had the confidence to question it. Thanks.

On the other hand

I am now bugged that I agreed with it being a Punctelia in the first place. As you say, the lobe shape is not right, and there are a very few linear pseudocyphellae. Maybe I was in that state of unreality between getting up and my first coffee?

Looking at it I can't

Looking at it I can't understand how I came to identify it as Punctelia - and I've usually had at least one cup of tea and put my glasses on before firing up the computer.......

Good to see you, Jenny

Don't worry. If it makes you feel any better, I have just been puzzling over a photo of an unusual white thallus on bark, with bright orange soralia... before finally realising it is old, eroded paint dotted with Trentepohlia. Oh dear.

I've spent time trying to identify paint too!
