Despite seeming variety of substrates and variability of lichen itself, I think it’s all A.caesiocinerea. Scattered on vertical cliffs and loose boulders, it’s one of the most common lichen at this location. I picked few samples just to verify, but precise ID of all the lichen bodies here is impossible: the substrate is all Baraboo quartzite, very hard and tough. The only way to get a sample is to find loose chip of rock with part of the lichen thallus on it.
