Pannaria immixta is a variable species, characterised by: the corticolous habit; the blue-grey, squamulose thallus; and the pale, orange-brown, gyrose-etched apothecial discs. Forms without such gyrose-etched discs are superficially very similar to Fuscopannaria crustata (q.v.), which has more rugulose ascospores and also an amyloid apical apparatus in the ascus.
