This large and robust foliose lichen is in the same league as Parmotrema perlatum and Hypotrachyna laevigata (both described elsewhere) but, unlike those two species, the lobes entirely lack powdery soredia. The grey thallus can have a green cast which can be a useful character in the field; it also has a tendency to tear and crumple easily so exposing the white medulla to light. It is mostly confined to old woodlands in western Ireland. Reactions: C+ red medulla. Western Ireland.
