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.
This looks to me more like poorly developed Hypogymnia tubulosa. Terminal soredia are tending to be capitate, and thallus lobes are rather narrow, with a convex, matt surface.
Or possibly the whole thallus is being attached by something - it does not look healthy.
H. tubulosa (foreground) and H. physodes (background) might both be present.
I have looked at quite a lot of H. tubulosa in the past month, especially in stressed and/or necrotic states, most of which make this one look quite well, and agree with Alan that the species in the foreground, at least, is H. tubulosa.
