Found growing on bark of broken tree branch. I do not know very much about lichen, but was able to find something similar, with black rhizines on edges, identified as Parmotrema perlatum. Am I in the ballpark with genus, and any idea as to species?
Much Thanks for any ID assistance!

for your help on this & other lichen.
I suspect the P. hypotropum group, though, because of the really loose, three-dimensional look of the thallus and particularly conspicuous cilia. You can verify readily by checking the underside. P. hypotropum group has large naked white splotches near the margin. P. perlatum and kin can also develop white splotches in age, but never so conspicuous as P. hypotropum.
I think we can rule out P. hypoleucinum. It should be very rare that far north in Missouri. There are no reports for it on CNALH outside of the extreme southern end of the state.
