Pannaria hookeri is characterised by: the saxicolous habit: black apothecial discs with a prominent thalline exciple; the small, narrow, thick lobes with a characteristic whitish grey-striate upper surface and distinctive whitish grey margins; and the saxicolous habit. It is the type of subgen. Cryopannaria P.M.Jørg. (Jørgensen 1994b: 202; 2000c: 405) which comprises P. dichroa (Hook.f. & Taylor) Cromb.,  P. caespitosa P.M.Jørg., and P. pulvinula P.M.Jørg., the latter two species from Bøuvet I., and the South Shetland Is., and from the Crozet Archipelago, Kerguelen, Marion I., and Prince Edward I. respectively (Jørgensen 2000c).
