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.
I think you might be right but I reserve judgement until I can return to the site and get a group in focus.
I have uploaded another for your interest - it was titled strepsils!
certainty can be sought from the emerald-green reaction that C. strepsilis has with bleach (eg Domestos or Milton Sterilising Fluid). No other Cladonia sp. reacts in this way.
On the few occasions I have seen this species, the basal squamules have dominated, but I think this is C. strepsilis.
Well, in the gloom of a 2013 Orkney afternoon I took out my GPS and located a small patch. At home, I did the test with cheap bleach and, well, hey! See third picture
So thanks again.
