Mexico has a whole crop of species I’ve never seen, but this isn’t entirely dissimilar from P. membranacea or P. praetextata. I vote against P. membranacea because it should have more sharply-raised veins and less-branched rhizines, and I don’t think it ever has such abundant phyllidia (lobules). Sonoran Flora verifies this latter point. I’ve seen P. praetextata do the bushy rhizines before (it is an exasperatingly variable species as currently circumscribed). The Sonoran Flora also suggests P. fibrilloides as a possibility, mentioning the richly-branched rhizines, but it says it should have up-turned lobe margins, while your specimen has distinctly down-turned lobe margins. Just thoughts.
