According to my sophisticated, high-tech measurement techniques (ruler on LCD screen) the lobes are ~1mm wide. This is definitely Xanthoria, not Candelaria. Probably one of X. fulva, X. oregana or X. ulophyllodes.

I know how to use my own website! Haha! ;) Even at full-res I can’t see if there are soredia or isidia. I presume there must be; any self-respecting fertile Xanthoria would have grown at least a few apothecia in this photo. This is why I’m still considering Candelaria. When young, it can show almost no soredia. I’m just not sure. What’s the scale of one of those little greenish/yellowish patches, anyway? Are we talking a few millimeters?

greenish-yellow, at any rate.

Surely you mean yellow? :) How about Candelaria or Xanthoria sensu lato? Hard to say without closer view.
