This was photographed near Port Pegasus, Stewart Island, in very poor lighting sorry. I can't quite figure out what it is. It doesn't seem wavy enough for Hymenophyllum flexuosum, It's not tufted so not H. pulcherrimum. H. pluviatile is not currently recorded for Stewart Island. Or coulsd it be a very large H. sanguinolentum? I've also found a very similar looking thing in Catseye Bay Fiordland. Any help would be much appreciated.
