Cladonia. Growing on drystane dyke. Small cups proliferating from the edges of the larger ones. Possibly C. chlorophaea agg.?
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.e. as C. chlorophaea agg.), but it has rather large granules inside the cup. Not possible to tell from the photograph whether these granules are or were corticate (have an outer skin), but if they did, plus the nature of the basal squamules, this would be C. pyxidata.
I am not saying it is C. pyxidata, and I do slightly favour C. chlorophaea, but I personally will not add agreement to either possibility.
