Hymenophyllum revolutum

This delicate little filmy fern is common throughout the country in damp bush.

It spreads by long rhizomes and can be found covering rocks and fallen logs, as well as being epiphytic on tree trunks.

The leaf edges are toothed.

Those little whitish structures are "indusial flaps" - they cover the "sori" which are groups of spores.
