Good question

Too small for Xanthoparmelia and interior is areolate. Doesn’t look right for Dimelaena (there’s a bit of Dimelaena at the top of the photo for comparison). Doesn’t look like Lecanora muralis, either, I agree. Running out of options! :)

What’s that white one in the second image?

It isn’t Lecanora muralis, is it?
