Rhizome long-creeping, much-branched, 0.1–0.2 mm diam., dark brown to black, glossy, with scattered brown or red red-brown, simple or once-forked hairs. Fronds 1–9 cm long. Stipe 0.1–7 cm long, unwinged, filiform, widely spaced; hairs similar to those of the rhizome, tufted near the base, scattered above. Lamina ± flabellate, divided into dichotomous segments, 2–4 times or very rarely simple, deltoid to very broadly obovate or round, 3–40 mm long, 3–34 mm wide, pale green. Ultimate segments 1–20, opposite, ascending, 0.8–11 mm long, 0.8–2.4 mm wide, glabrous; margins bearing small persistent teeth with fugacious simple or forked hairs. Sori marginal, solitary or rarely in pairs, at the apex of the ultimate segments, deeply sunken in the lamina; involucre obcordate or cuneate-obconical, sometimes bilabiate, 0.5–2.3 mm long, 0.8–2.5 mm wide, apex retuse, erose or toothed, each tooth bearing a reddish forked hair; receptacle included.

Rhizome filiform, sparsely clad in brownish hairs, especially at base of rather distant stipites, glabrate in age. Stipes filiform, 2-5 cm. long, bearing slender branched hairs. Rhachis hardly developed; veins radiating from base of lamina, several times forked, with or without hairs. Lamina delicate, pellucid, subreniform to oblong in outline, 1-3 cm. long and broad, flabellately divided into oblong segs, retuse at apex; segs distinctly to obscurely toothed, teeth with branched hairs. Sori immersed. Indusium obconic; mouth truncate to obscurely 2-lipped at apex, bearing delicate hairs. Receptacle not or barely exserted.
