Oooh, here’s an unpublished list from several years ago

Caloplaca camptidia — Lecanora-like, on bark
Caloplaca cerina — gray thallus and rims, on bark
Caloplaca chrysophthalma — bright yellow and orange, on bark
Caloplaca cinnabarina — solid smooth bright orange, on siliceous? rock
Caloplaca citrina — sorediate yellow, on calcareous rock
Caloplaca epiphora — extreme south?, bright orange isidiate, on bark
Caloplaca feracissima — the sidewalk thing
Caloplaca flavocitrina — like citrina but with better-developed lobes, on siliceous rock
Caloplaca flavorubescens — ?, on bark
Caloplaca flavovirescens — smooth thin yellow thallus, orange apothecia, on siliceous rock
Caloplaca granularis — ?
Caloplaca holocarpa — no thallus, orange apothecia, on siliceous rock or (sensu lato) on bark
Caloplaca pollinii — ?
Caloplaca reptans — ?
Caloplaca saxicola — small orange rosette, on any rock
Caloplaca subsoluta — small scattered orange areoles and orange apothecia, on mostly siliceous rock

I see that C. feracissima and C. subsoluta are both on there. No indication of abundance in this list, and indeed, some names might have been corrected in the interim. But It’s a good starting point!

Second C. subsoluta

There are a few specimens from N GA at NY. Other option is C. flavovirescens, but would expect more vegetative thallus to be present.

Looks to me like Caloplaca

maybe C. squamosa or subsoluta?
