Grazed lichen
Closeup
Description:

This looks like a patch of lichen that has been grazed in an interesting pattern, perhaps by a slug or snail. I don't think the lichen is identifiable, but perhaps the grazing pattern rings a bell for the lichenivore.

Identifications

Caution: Do NOT use iSpot to identify fungi to eat!

Some fungi are very poisonous so a mistaken ID could have serious consequences.

Species interactions

No interactions present.

I agree with moremoth

This looks to me like a Lecanora, half eaten by a very choosy or creative invertebrate.

Grazing

Yes, I am sure it is a grazed lichen. I have added a closeup at 100% from the same photo that shows clearly the "jam tarts" on the lichen and that the brown areas are the bark of the twig. I wondered if tree slugs were responsible, but there must be many other possible culprits, and I thought that maybe the pattern of grazing might give a clue.

Yes

that looks like a Lecanora. Not allowed to withdraw my earlier suggestion :(
