Uncommon, on rocks in shady humid conditions. Indusium c 1 mm long, fronds c 2-8 cm long Skye ID: If indusia present, easily told by their toothed margins, as in picture on left (indusia are the cups surrounding the dark sori). If not, best told by dark veins not reaching the end of the frond segments. Other features: Indusia about as broad as long, the two valves somewhat flattened together, more like an envelope than a cup. Pinnae tend to be divided into more segments than Wilson's Filmy Fern. |
