Looks like another I’ll have to come back to, the rock is near home and large enough that I doubt it will be going anywhere soon.

One of the C. arenaria group maybe?

There are six species listed in the Sonoran Flora with “scant or not evident” thallus. C. arenaria and C. marmorata have “dark red-brown” apothecial discs, C. luteominia has thick rims, C. ludificans has a faint translucent yellowish thallus, then there are two orange-disked ones which differ only in spore size: C. nashii and C. crenulatella. Good luck!
