I think not Parmelia

Parmelia should be black underneath. I’d consider Physcia first, or maybe one of the Heterodermia that’s corticate underneath (many of the tropical ones tend to be corticate underneath, it seems, e.g., H. albicans or H. speciosa in southeastern US).

Also note that this has a “dull” appearance — suggesting a “physcioid” genus (i.e. in the Physciaceae), _rather than a “parmelioid” genus (e.g. Parmelia obviously, or Parmelina, Parmelinopsis, etc., all in Parmeliaceae but distinct from the “cetrarioid” genera, also in Parmeliaceae).
