I’ll settle for Hypogymnia, Jason. H. heterophylla does look possible from the second photo, though.

Also found another single specimen of Hypogymnia, but photos didn’t turn out. Single strand about 4-5 inches in length, sparse branching. Compared to the other clumping Hypogymnias so common the area, sort of stood out like a club moss among ferns.

Could be H. heterophylla

The non-imshaugii species are tough. You’re looking for pinched side-lobules particularly. This doesn’t seem to have any but it doesn’t have the open long branches of imshaugii. The dark inner surface would indicate either H. inactiva or H. heterophylla. Lobules would indicate H. enteromorpha or H. occidentalis.
