Important thing to note is whether the rhizines are brushy-tipped (P. canina) or if they are narrow and rope-like (P. membranacea). These look like they may be too thick and fuzzy to be P. membranacea. P. praetextata is in this group, too, but would have even less fuzzy rhizines.

(I believe the technical term for the undulating surface is “bullate”.)
