Lichen found on vertical wall
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.
Can't see details of the discs or thallus margins clearly enough for a definite suggestion, but Haematomma ochroleucum is a crustose lichen with red apothecia that could be worth checking.
Any chance of some more photos?
