Both plittii and conspersa have stictic + norstictic (K+y to red). Difference is lower surface as you say. Sorry!

X.conspersa or X.plittii

Those are the most common here (you’re right – the other two species don’t seem to be well known – I can’t even find any illustrations of X.norhypopsila). X.conspersa is supposed to have black lower surface, while X.plittii – pale to brown lower surface.

Forgot about X. plittii

X. subramigera is a small species, wouldn’t look like this, I think. Never heard of the other two, so maybe we can conclude they are more rare? But both X. conspersa and X. plittii are good possibilities. First is K+y/o, second K+y to red, I think. Otherwise, probably not vastly different.

4 or 5 species

Of the isidiate species, there are (per Thomson):
Xanthoparmelia conspersa
Xanthoparmelia dierythra
Xanthoparmelia plittii
Xanthoparmelia subramigera
Another, recently added species, is Xanthoparmelia norhypopsila, but I don’t know if it’s isidiate. Perhaps, thre are more fresh records from CNALH?

There aren’t that many Xanthoparmelia in the east, right?

Well, sure there are lots, but there aren’t insane numbers like in the desert southwest. (If that’s a lot, look at a checklist for South Africa someday.:) This is entirely plausible. Spot test verification would be nice, but the odds are good anyway.

Tentative ID

No specimen were taken, only visual ID, for what’s it worth (not much, I guess).
