Zaca is clearly onto something here.

Looking more closely, I see rims around those “perithecia”. I agree, these have to be apothecia. I don’t know Protoblastenia, I’ll trust you on that!

Alan, was this on basic or acidic rock, do you remember? That could be important.

which has a non-violet K reaction.
(It seems clear to me that the fruitbodies are apothecia, with several young in the last photo)

Lack of K reaction rules out Caloplaca

Although this looks more like a peritheciate thing. Pyrenula??

Turns from orange to brown in KOH. No change when dilute bleach is added to the KOH spot.
