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!

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.
