I did not take to much attention to the specimen, though it’s a clean one. I will investigate. Thanks.

One of the “effigurate” species

C. flavovirescens has an indistinct margin. This beautiful specimen has well-developed radiating lobes at the margin. That puts it in “key C” in the Sonoran Flora: (no telling which additional species you may have, sorry)

C. eugyra – ?
Xanthoria elegans – has distinct lower cortex and is raised slightly from rock
C. trachyphylla – has roughened texture, very common
C. brattiae – on rocks by the sea
C. saxicola – relatively short lobes?
C. ignea – fairly reddish, calcareous rock
C. impolita – ?
C. appressa – ?
C. texana – ?
