I found this fern today and since it's December here in Maine with a little snow on the ground and 22F, it must be some sort of an Evergreen Fern, but I can't key it out. They are 12-15 inches tall and 3 - 3 1/2 wide. Sori are on the back. The stipe and bottom part of the rachis is brown with a few scales. I don't see any fine hairs. The pinna are 2x cut and they were clustered. The venation is interesting and I thought that would help with ID, but it didn't.
