I find this is very hard to distinguish from P. canina. But I think I’ve finally got it. Note the narrow sharply-raised light-colored veins and non-flared rhizines of the underside. These are very good examples. Note that you can almost always find a few tiny lobules along cracks or scars in older parts of the thallus. I don’t believe this ever happens for P. canina.
