#shield lichens

A quick update on the lichens from yesterday: trying again, I got an identification of the ones with the little cup-structures as "Rosette Lichens, Frost Lichens, and Allies" (which is a charming way to put it) from iNaturalist. The closest type seems to be Star rosette lichen, which is very very common, so this might well be it. I've included one photo with my fingers to show the scale of these (very tiny). And the last pic is another of some shield lichen; interestingly two-toned.
