like…“having a frost-like or floury surface covering of pruina.
Often caused by calcium oxylate crystals in lichen thallus.”

Dictionary of the Fungi, 8th Edition.

Cool details! You’re making a lichenologist outta me, bit by bit!

……In WI it’s scattered over the state.

Pruinose disks!

Pruina elevates this far above the “little black dot” trashcan! :) One of the Sarcogyne typically has pruinose disks. S. regularis, I think. Most Sarcogyne also show at least some splitting along the margins, too.

Discs, not Dots!

I know I’m going to be accused of uploading yet another batch of non-descript black dots. Mind you, though, these are not dots, but little discs. And look how they reflect the sun at certain angle, asking to be IDd. These are in public place, so there is no way to collect a sample. I believe the substrate to be a dolomite.
