Harris was talking about the Ozarks. So maybe X. subramigera is a southern thing. CNALH maps:
Wow, complicated. To oversimplify dramatically: conspersa = widespread but most common in east, plittii = widespread but most common in west, subramigera = common only in a few scattered localized areas, not in Great Lakes, maybe tending toward southern.
According to Thomson, the most common isidiate species around here seem to be X.plittii and X.conspersa. At the time of Thomson’s writing, X.subramigera was only found in two locations in the state, both in the south (the location in question here is up north).
For isidiate species, according to J.Thomson “Lichen of WI”, pale lower surface (see the small piece in the middle of the bottom photo) would indicate either Xanthoparmelia plittii or Xanthoparmelia dierythra (The latter I’m not at all familiar with), the only difference being: the former has stictic acid and the latter has norstictic acid (it doesn’t say how one can see the difference). There is also X.subramigera, but I guess it looks slightly different?
