Looks like a sensitive fern (onoclea sensibilis) to me. That said, fern ID is tricky. For many, you need the blade shape (wider at top, bottom or middle?); the shape of the sori (sort of like seed cases, on the underside of the pinna (blade); whether the stipe or rachis (stem-like parts) are smooth/hairy, round or some other shape; and sometimes the shape of the croziers (the round fiddlehead-like parts that come up in the spring).
