The pigment looks like the yolk-yellow of calycin, not the orange of most anthraquinones… hence, I am inclined to say that Candellariella should win out over Caloplaca.

I followed the directions in the Lichen name description to make NaOH using red devil drano and tested two spots. The first added picture I added a small drop and got what appears to be dark brownish red coloring, not pink. For the second added picture I dipped a toothpick into the NaOH and scratched the lichen with it, which got a greenish reaction. I’m thinking the first picture is more of what you are looking for? Though I added both anyways.
