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.
With only the details in the photograph and no information as to habitat, chemical reactions and possibly the colour of the thallus and podetia under UV light its not possible to identify accurately which Cladonia species it is.
The podetia (stalks) seem rather too squamulose for C. ochrochlora and there are several species with similar brown apothecia (fruiting bodies).
Cladonia's are even more variable than other lichens!
Sensible words but for once I disagree with you - about it not being possible to identify. I seem to have looked at a lot of C. squamosa recently and I am happy that this is what it is.
