I wasn’t prepared to collect from rock so I snapped a few photos, but I plan to get back and see if I can extricate a small piece for micro review. From photos, C. arenaria apothecia are flat-topped where these seem to be very convex, almost bullate or rounded.

This must key out as C. arenaria

But it doesn’t look quite right, does it? I wonder if the spore dimensions, chemistry, anatomy of apothecia, etc. would match…
