Ardvreck Beagles and Pharaoh Hounds
Hymenophyllum wilsonii Hook Wilson's Filmy- Fern from Milkingstead Wood, Eskdale, Cumbria [SD1531199579].
Taken on a very wet and soggy 18th July 2011 by N. Blackstock.
Note the overlapping, mat like fronds, The mid-vein fully extending to the pinnae margin and the smooth indusia.
The latter easily separates this from Tunbridge filmy-fern, which is also found in Milkingstead Wood.
