Yeah, I don’t understand any of these placodioid species yet. You’ve got great material to learn from. I’m so jealous.

I don´t think so.

According to Irish lichens : in C. saxicola the “Convex lobes are short, pruiniose, splayed and often down-turned at tips”, which is not the case. In this specmen the pruinosity is restricted to the center of thallus. Maybe, as you mentioned in a previous comment, there is a different understanding of C. saxicola in the two continents, America and Europe.

What about C. saxicola?

I’m thinking of the apothecia starting out immersed so close to the lobe tips. It can be pruinose, right?
