Growing on rock narrows down options dramatically. P. plittiana is only one regularly on rock reported from Ozarks region. Others occasionally are found on rock, though.

P. plittiana is C- and K+ yellow turning bright red (norstictic acid)
P. velata is more verrucose, paler, and K- and C+ red, more common on bark
