Rock polypody

Polypodium virginianum


These are golden-brown sori (collection of sporangia/fruiting bodies) on the underside of a fern frond.


Grows in the cracks of a shale wall across from a waterfall, a high humidity area at Watkins Glen State Park.


The presence and morphology of the sori helps to identify or confirm the fern species.
