for the links. Any help is welcome, especially when one gets lost with a genus having dozens of species and very well represented here.

I don’t know how accurate this would be applied to Portugal…

but you might check the Pertusaria key in Richard Harris’s More Florida Lichens, Including the 10¢ Tour of Pyrenolichens There are a whole pile of these things that all look the same but have subtly different chemistry. Beware some of the names are out of date. You might double-check against James Lendemer’s Preliminary Keys to the Typically Sterile Crustose Lichens in North America to catch taxonomic corrections.
