Following terricolous couplets

I didn’t get to the punctata/pullata couplet. In your experience, could specimens like this on soil be strays from either the saxicolous or corticolous groups? The Sonoran Flora V.3 key gets pretty quick from couplet 17 to 38 to 77 with specimen occurring on soil, and with K- and C- spot tests (assumed) it drops us at the undescribed sp. 1 and sp. 2. I did have an expectation that this scant specimen could be saxicolous, and doing ok on the sand grain soil. So, Buellia sp. it is!

You’re thinking the spores are too big for B. punctata / B. pullata?

These big-spored specimens with well-developed thallus stump me.
