Recognized by sight: Well, you would obviously know better than me, but based on the images and descriptions I have been going through lately, I think it is a good candidate for C. brattiae. The lobes are bubbly, not very flattened. The apothecia are certainly “abundant” and central, while the thallus is orange. A lot of the pictures I have found of it look like this, but I realize some of these species are extremely variable.

I do not know either C. impolita or C. brattiae. Sometimes I wonder if I even know C. ignea!

Wetmore & Kaernefelt 1998 do mention that impolita has flatter lobes, and that they broaden toward the tips. Unfortunately I did not make any notes about the anatomy of the cortex (brattiae has anticlinal prosoplectencyma, impolita cellular paraplectenchyma).

I think I tentatively ruled out brattiae because this was nowhere near the immediate coast. But the rest of the site clearly had a littoral community with abundant Niebla and other maritime species.
