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.
We need a closer view, but I suspect this is Cladonia rangiformis, which is a common bushy species on dunes. [If not this then it is C. portentosa, but it is a bit green for that.]
