I upload a photo with the spot tests on soralia of one of the specimens. The same result. This species is very commom locally, but away from this place I didn’t found it.

Good to note spot test on soralia, too

P. hemisphaerica, for example, apparently only has C+ soralia, not thallus. I can’t find a description on this species, but given the name, I would expect the soralia to be more “hemispheric” than yours.
