I think. It has those broad rounded lobes and general look of a Parmotrema. Since it is fertile and lacking (?) soredia or isidia, that leaves only these two species. KOH on the inner medulla would distinguish the two species: P. performatum is K+ yellow to deep blood-red quickly; P. michauxianum is K-. (Also you might verify that it doesn’t have a dense network of fine little cracks all over the upper surface, which would indicate Rimelia cetrata.)
