Sonoran Flora says the apothecia become strongly convex in age. I guess I’m just used to seeing young specimens. The other observation you mention looks right, not sure what it is about this one that seemed “off”.

I found it very similar to observation 97922, including chemistry, and thought that it is of the same species. My microscope is not working properly, but I will observe the spores, if I can. Thanks, Jason.

Have you checked the spores by any chance?

In my very limited experience Lecidella has flatter and distinctly shiny apothecia, and the thallus is more verruculose. Could this be Buellia (s. lat.) instead?
