I think this is a fruticose lichen as it had quite a lot of fronds or branches growing upright, it was a silver-grey in colour.
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.
It certainly is. If you add a revised ID that also includes the scientific name (Evernia prunastri), you are likely to attract agreement, and it will link to other observations.
It's actually foliose. A full explanation can be found on numerous other postings of this species.
Thank you Nigel for the identification and also for the helpful comments.
