It is shown by use of a newly discovered, old photo of the missing type that Siphulina orphnina (Hue) C. W. Dodge is identical with Pannaria caespitosa P. M. Jørg. The new combination Pannaria orphnina (Hue) P. M. Jørg. is made, and the name neotypified. Parmeliella austroshetlandica Søchting & Øvstedal is shown to be a species in the small subantarctic genus Peltularia R. Sant. (Coccocarpiaceae), and is transferred to that genus.
