Fruiticose lichen found on a stone wall, growing out from the crevices. Need help with ID if possible from the photo.
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 think it is a Cladonia. There are a few species of Cladonia that look the same. It could be Cladonia portentosa.
Thank you. I've checked the British Lichens species gallery and it looks very like.
