Growing on lower branch of large, dead, open-grown Quercus macrocarpa in wetland. I was calling this P. caseana, but wondering if P. borreri seems to fit better?

But yes, looking at my own notes, too, it’s all western. As far east as the Black Hills. I thought maybe Andrew had showed me a specimen from WI, but I guess not.
It’s not actually that bad. (So long as jeckeri and caseana stay where they are supposed to!)
pale underside . . . caseana / jcekeri
C- . . . reddenda
C+r . . . borreri
They do all have a different gestalt, as well. Well, again, not caseana and jeckeri. The pruina that is supposed to distinguish them is mighty subtle. But the rest aren’t bad.
I was reading a 2010 paper on the Punctelia situation and was a bit confused about distinguishing jeckeri/reddenda/borreri/caesea. But my understanding was that Jeckeri, reddenda (and borreri hah) didn’t get into WI.
(and P. jeckeri is very similar, by the way). But the underside is as black as it gets. Some variation is to be expected in caseana/jeckeri, but it should never get as dark as either this specimen nor the last.
