You can see the white veins and rhizines a little in a few places, but to be 100% certain this isn’t P. praetextata or relative, it would be better to have a closer look at the underside. P. membranacea has very narrow, distinctly raised veins that form a somewhat diamond-like pattern, and are typically pure white for some distance back from the margin. P. praetextata… well, can be all over the board, but rarely combines all those characters. Also, with a handlens you can verify that the rhizines and veins both are covered with tiny erect white fuzzy hairs. (Again, praetextata can do this, too, but never both rhizines and veins, or so I’m told.) Lastly, you are in prime habitat for membranacea.
