Rhizome long-creeping, filiform, branched, black or dark brown, glossy, with sparse reddish or golden brown hairs. Fronds 0.35–4.5 cm long. Stipes slender, widely spaced on the rhizome, 0.25–8 mm long, narrowly winged at the apex, usually with a tuft of reddish or golden brown hairs near the base. Lamina simple or 1 (–3)-forked, linear, narrowly oblong to elliptic, 2.5–35 mm long, light or dark green, glabrous except for scattered tubular or flattened reddish or golden brown hairs along midrib and at the base of the involucre; segments 0.7–3 (–3.5) mm wide; margins entire, undulate, composed of 1 or 2 rows of glossy, black cells; apex of non-reproductive lobes rounded, obtuse, rarely acute. Reproductive lobes rounded, truncate or notched; base tapering into the stipe; midrib black, glossy. Sori borne singly, at the apex of the lamina or its lobes; involucre round to ovate, bilabiate to the base or with a very short tube, 0.8–2 mm long; margins entire, composed of a glossy black band 2 or 3 cells thick; receptacle included.
Wet sclerophyll forest, subtropical and temperate rainforest, on moist rocky outcrops as a lithophyte on sandstone, granite, granophyre, rhyolite or dolerite, as an epiphyte on tree ferns, tree bases or logs, or occasionally as a terrestrial (Garrett 1996; Bostock & Spokes 1998).
