In shaded recesses of possibly calcareous rock, with moss.
Thallus seems to be small green imbricate squamulose areoles, with orange-brown biatorine apothecia.
Spores simple, narrowly ellipsoid, hyaline, with several oil drops? Average size 16.0×5.4µm (n=5).

and leave this one for now. It was very scant material, i was hoping with the apothecia color it might go to genus easy, but I too went to Lecanora and decided quickly not to go too far.
Might be a poorly-developed or aberrant Lecanora. If this were mine, before anything else, I would try to get an ascus stain. Also, I would verify for sure that all the spores are aseptate, either by clearing with a flame or in K or K/I. Some of the spores in the photo are definitely aseptate, but sometimes septae are very subtle in water and can be hard to spot.
But also, unless you have a good deal more material than what is shown here, you might be better off limiting your expenditure on this one! Definitely something worth looking for next time you’re out.
Maybe I’m tired, but I got nowhere with this one.
