of the thallus is a good explanation for the weak chemical reactions (of course, I meant K+r not C+r). On the other hand, as you said, looks more like P. reticulatum. So, I believe this species is the better choice.

Maybe just and old, brittle thallus, then?

the specimens of P. reticulatum that I found before, in particular at that place, all had C+r (strong) reaction. That’s why I thought that could be P. chinense.

finely cracked?

Looks like the surface is finely cracked, suggesting a Rimelia instead, like Parmotrema reticulatum.
