fruticose greygreen lichen on stone
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.
The specimen doesn't seem to be in very good health!
Left hand side there is a Parmelia (blue-grey lobes with white marks).
In the centre nearest to your finger is probably a Hypogymnia and what might be powdery patches of a Lepraria lower down
