This looks right

The comment about the lower surface being yellowish is, I think, wrong. I find it is white just like C. apodocarpa (which except for color looks nearly identical). But the usnic acid is present not only in the upper surface, giving it a warm green coloration overall just like this, but also in the medulla, so the lower surface should react KC+ y, fairly strong actually, if I remember right.

(Be sure to do your K test on the lower surface of the squamules of these apodetiate species, by the way, should be much easier to read, although ambiguous results are by no means uncommon as you well know!)

To be identified.

My preliminary testing didn’t produce any visible (to me) changes with either K or C. I also don’t see any cream or yellowish lower surface that’s suppose to come with C.robbinsii , but I don’t see that in Sharnoff’s photos either at:

(one of the photos there is from the same county in Wisconsin, less than 20 miles from this location). It might end up being C.apodocarpa too.
