I was hoping C. galactophylla was one you were familiar with, zaca!

I’ve noticed that European C. saxicola is very different from what we call C. saxicola in western North America. I’m not sure what to make of that.

Fortunately, there are (relatively) few Caloplaca reported for Andrew’s region.

but I’m far from being an expert in any lichen genera, let alone Caloplaca, one of the biggest and widely represented here; I have no checklist, key or any other of the tools necessary to deepen the knowledge on it.
Regarding this particular observation, I agree with Jason that it reminds C. saxicola (I don’t know C. galactophyla), but probably there are others to consider; the fading colors at the margin of thallus almost resembles those of C. aurantia that nevertheless has a distinct thallus; Summarizing: I don’t know.

Zaca is the expert

But it sure doesn’t look at all like the stuff I’ve been calling C. saxicola… (Granted, I haven’t done much collecting on limestone or dolomite.)

C.galactophyla or C.saxicola?

These were very difficult to photograph in the blazing sun on the open bluff. So pardon bad pictures, but I want to know what it is and possibly re-take those pictures next year if this is worthy of the trip there. The substrate is supposed to be dolomite (or dolomitic limestone as it’s sometimes called).
