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?
