One of the first couplets in any key to Caloplaca is whether the thallus contains anthraquinones or not. It helps determine which group(s) to consider. It’s particularly subtle in this photo because it blends so perfectly with the substrate! I don’t know if anyone ever looks at these comments when browsing photos on MO, but if so, I thought it’d be nice to bring attention to this feature.
(According to the literature I have access to, I completely agree with your assessment, for whatever that’s worth.)
Just wanted to make a comment about that because I failed to see it the first time through.
