The Black Haired Filmy-fern is common at Ferncliffe.
Attractively covering boulders, because of its small size it it is easy to overlook. The stipe is winged, hence the family Hymenophyllaceae. The spores are produced in a tiny capsule. These are seen in the bottom picture as translucent bodies, (the third from left is maturing).
I think that the few black hairs at the base of the stipes is enough evidence to warrant its specific epithet "black haired."
