Recognized by sight: Agree with zaca completely. In southern California, these ones on rock, especially rotten granite, but also on more solid rock, always key out as D. scruposus. Especially common in lower-elevation chaparral on south-facing slopes, in my experience.

we have a species of Diploschistes that is very similar to this one. It has a brownish thallus and often presents a green-blue tone and covers extense areas of siliceous rocks. While the mature apothecia seems of lecanorin type, the youngest have urcelate margins (you can see them at the bottom right corner of the photos).
