Substrate: rotting stump.
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.
Cladonia polydactyla was my initial assumption, but I'm doubtful now.
Many thanks Alan. I remember considering C. macilenta at one point, but I think the branched and twisted podetia put me off.

Could this be Cladonia pyxidata?
C. pyxidata has larger, corticate granules in the cups, although I haven't yet seen it. I think the granular soredia, gradual tapering of the cup and brown pycnidia on the margins make C. chlorophaea a strong possibility.
I'd agree with C. chlorophaea as the best bet for the cups, though from this angle I'm not sure if the cups contract rapidly enough to be C. fimbriata (the granules do look a bit coarse for fimbriata).
I deliberately refrained from putting an ID to the cups in the foreground as in my view not enough is visible and speculation is probably unwise.
However, what we can see suggests C. grayi - but best not identified from a photograph. Distinctive under UV (medulla brilliant blue-white).
