Lecanora hybocarpa, Buellia stillingiana, Pyrrhospora varians
bark. Coweeta in Nantahala NF
Collected for Lichen Bioblitz. Sorry to put three species on one spotting. I'm not the one who ID'd these, and I can't tell them apart. Online descriptions are highly variable. If anyone can point out which is which, I'll separate into additional spottings.
