Hmm, could be... Maybe Green Fantasy or some such, but would need to get a better idea of the overall shape of the frond. This is fully bi-pinnate, so I'm not convinced it's a Neph sp. just based on the one photo. Check to see if the new growth has a red tinge to it. If so, this may be Didymochlaena Truncatula; Mahogany Fern.
