I didn’t find any apothecia, but I could of missed it, I’ll take another look when I revisit it.

Also, I added some attempted chemistry to observation 70022 a little while ago and I think you may of missed it. :)

Start with a K test. I suspect Caloplaca citrina (K+ wine-red as with all Caloplaca and the rest of the Teloschistaceae), but only one way to be sure. Did you find any apothecia in all of that? The whitish dusty look is probably pruina, a phenomenon that seems to be common for lichens growing on very calcareous substrates(?)
