I’m not sure I could tell them apart either

I’m still looking for specimens of both. Hopefully when seen side-by-side it will be clear.

Unfortunately I didn’t check the medulla.

The two species you mentioned are very similar and I couldn’t decide which one it is.

Also consider Parmotrema stuppeum

Long powdery (fine) soralia and very few cilia can also be P. stuppeum. P. perlatum is definitely possible, too. Did you do K or C test on the medulla? There are a number of chemospecies in Parmotrema, so it’s always worth testing every specimen you collect.
