Assuming this is all dry…

I would say that photos 2, 3, 4, 7, 8 are Ropalospora viridis, and the rest (1, 5, 6) are Biatora printzenii.

Which one is Biatora printzenii?

I think photos 1, 5 and 6 — the brightest ones with most discrete soralia — are most likely to correspond to the speciumen which was C+r and P+o (gyrophoric acid and pannarin).

But as you can see, these things are variable and subtle at the best of times

Might be best to leave them together and say: both Biatora printzenii and Ropalospora viridis were found in the material collected on this tree.

Yeah, there is a bevy of things here,

I can see Lecanora thysanophora in the third photo too.

There may be photos of two or three different species here

Some other options (consistent with the UV+ dull yellow) are Biatora chrysantha, B. pontica and B. printzenii. The first and last in particular can look quite yellow, especially when damp.

Jim Bennett thinks it’s Chrysothrix, like C.flavovirens or similar

Probably a long shot…
