Notes: Dry open oak woodland-scrubland interface with patches of bare rocky red soil partially vegetated with mosses and terricolous lichens.
Thallus yellow, areolate, C-, K-, KC-, UV+Orange. Thallus deeply attached to soil with pseudorhizines, and thick layer of rhizohyphae at soil surface just beneath thallus (if I’m reading the morphology right).

I’m told that it is evidence of late-successional soil crusts: Cyanobacteria and actinomycetes come first to stabilize the soil, followed by opportunistic species like Placidium and Collema, then finally you get beautiful species like Acarospora schleicheri, Squamarina, Fulgensia, etc. Or something like that. ;)
asci full of spores.
I just observed this species twice at the same place and, meanwhile, its habitat was destroyed.
with some micro photos later this week hopefully. Anything in particular that you would want to see to be more confident with the ID?
Another one to join the list for microscopy. Good luck!
