Once again the details

are important to decide between closer genera. I will try to see what are the most commom species of Parmotrema in the countries of this zone in south Europe. Thanks, Jason.

I’d say Parmotrema

Platismatia would generally be more wrinkly. Platismatia glauca can be this smooth, but its soredia/isidia would be more coarse and wouldn’t be in such well-defined soralia.

But this does look just like several Parmotrema. There are a few that have “capitate” fine soralia like this, but fewer have no cilia (as with yours, apparently). P. reticulatum should have more conspicuous fine cracks on the surface. P. arnoldii and P. perlatum both should have conspicuous cilia. P. dilatatum is very promising. There’s also P. cristaferum, and undoubtedly several European species. I think you should have quite a few species in Portugal and the rest of the mediterranean.
