Thanks, B. alboatra is a good candidate

But B. disciformis doesn’t grow on rocks, and B. punctata — none of the many species lumped under that name! — doesn’t have such a well-developed thallus. B. alboatra has lovely submuriform spores… too bad we can’t see them! :)

The similar ones I think are

but for some reason I’m drawing a blank on candidate species…

One way potentially to verify the genus at least is to slice one of the apothecia open. You can often see blackish streaks (dark spores) through the otherwise whitish hymenium, even with a hand lens. Lecidea and Lecidella would look distinctly “cleaner”, often even with a greenish or bluish tint to the surface (epihymenium). Might be worth a try…
