Wish I’d gotten some better macros. I’m not sure about this, but neither gametophyte/sporophyte look right to me for a liverwort.
Found at one of the few sites where this species is known to occur. Pinna bases don’t overlap the rachis, blade less than 3cm wide, sori 1-3 on basiscopic sides of asymmetric pinnae.
Uncommon on exposed limestone in mesic mixed hardwood forest
