Thomson lists C.sideritis in Wisconsin south of the tension zone (that’s where we are).

I think the gray thallus and margins really narrow it down nicely. I believe this has to be C. sideritis. (Used Bruce Ryan’s unpublished keys: works out to key 3-D-1: on rock, thallus gray, well-developed, apothecia orange. Still lots of species in that key, but the combination of pale gray thallus and same-colored rims with bright orange disks apparently rules out everything else.)

Jason, I see you’re patrolling the MO again – you beat me to my own observation :-)))

Yes, these are on granitic boulders (seen on bottom photo) and from afar blend in with grey Phaeophyscia rosettes. Being in public place and on granite, I was only able to scrape off some apothecia: don’t know if it’s going to be enough for an ID.

on rock?
