F. caperata isn’t uncommon on rock in the north, apparently. I was seeing it regularly on rock in the Black Hills, for example. But I have yet to see it on rock in the southeast. And these photos are excellent, clearly showing F. baltimorensis. F. caperata is sorediate, or at most coarse soredia arising on verrucae. F. baltimorensis has fully-corticate bumps and pustules that break down in age into flaky/chunky “schizidia”, rarely into coarse soredia. Look at fresh pustules, that’s where the difference is most clear.

Flavoparmelia baltimorensis?

I think it’s got to be F.baltimorensis, since it’s on rock – they’re nearly identical. Jason, where are you?
