Could be, but it also looks exactly like C. luteum

Easy to put the question to rest by looking at spores. Or even algae. I think Coenogonium all have Trentepohlia instead of Trebouxia - look for the little golden oil drops in Trentepohlia. But spores are easiest. Caloplaca (and almost species in the Teloschistaceae) have distinctive polarlocular spores, which is to say 1-septate spores with a very thick septum penetrated by a narrow canal. Coenogonum have normal 1 or more septate spores with thin septae.
Looking at other obsies on MO…

Caloplaca seems more promising… something I’m missing?
Will be trying my luck with mico on lichens this year, and incorporating them into PSH.
