I had doubts and apparently chose the wrong one. Thanks, Jason, for your comment.

Right shape but wrong soralia

It doesn’t say in CNALH / Sonoran Flora, but the soredia are very coarse and isidioid, also (it does say this) soredia occurs only under lobe tips, not on the upper surface. The material I’ve seen (it’s extremely common in the Santa Monica Mountains in southern California) doesn’t even look sorediate, it just sort of looks like the lobe tips are breaking apart.

This must just be an extreme form of P. tribacioides?
