with the dark apothecia really start to strain the bounds of acceptable variation for decent species. But some Caloplaca are anything but decent, so who can say??

I can only guess whether it’s all one species or many.

I know C.sideritis is very variable, but the variety of different thallii at this site was really unsettling. I took some samples, thank goodness – not an easy feat on granites.
