Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
It looks a bit like Hypogymnia physodes, with its shiny inflated lobes and black pycnidia, but the wrong colour. Perhaps dead or dying H. physodes?
Edit: Thanks Jenny. I was toying with Xanthoparmelia, but don't know it anywhere near well enough.
It's probably safest to stick with Jenny's identification to genus, as individual species in this group show a lot of morphological overlap and are best confirmed with chemistry.
However I don't see any isidia - normally abundant on X. verruculifera, at least in my own experience. It looks like X. pulla to me.
