I’d prefer a better shot of the underside

The rhizines of P. canina should become bushy and confluent back from the margins. Also, the veins generally darken back from the edge, as well. In P. membranacea the rhizines will stay pointy and slender and discrete throughout, and the veins are creamy white throughout (usually). The other one to consider is the non-phyllidiate form of P. praetextata (actually a good deal more common than the phyllidate form!). It’s somewhere in between. It can have split, fuzzy rhizines near the margins like this one, but they should become more discrete and rope-like toward the center, instead of woolly like in P. canina.
