It's time for yet another ID attempt based on insufficient evidence~ (but sufficient enough to get to crack those guides).

Found 1200m high in Vercors (France) on a tree bordering a clearing, we have *possibly* here:

- Fruticose on the left: Ramalina... farinacea? But no flour aspect...
- Brown ones: Melanohalea something?
- Foliose grey: ... Too blurry, an even unsurer Parmelina?
- Moss: something Orthotrichum?

Assuming they are the same species, and I wouldn't bet on it, here's a closer look of the #moss and the brown parmelioid #lichen (a term cribbed from Wikipedia)

My guide for tree lichen indicates 'no risk of confusion' for Ramalina fraxinea, so I will present this one with slightly less doubt.

(The green one on the bottom right looks interesting but alas, I did not take a picture focusing on that one, I'll admit I was taken with all the other fruticose lichens on that same tree)

'What other fruticose lichens', you ask?

Well, those two, which could very well be a Ramalina fastigiata in the right and... A Ramalina also on the left but it looks different and I'm reaally not sure which one. Another fraxinea?

There was also this, well, Ramalina again, possibly farinacea, growing esthetically in the middle of a Parmelia (saxatilis?)
