Plants terrestrial or epilithic. Rhizome subterranean, short-decumbent, branched, to 2 mm in diameter, densely set with thinly crustaceous, castaneous, pluricellular, uniseriate hairs, apical cell small and thin-walled, to 4 mm long. Fronds approximate, dimorphic; stipe not differentiated from lamina; lamina coriaceous, sterile lamina simple, narrowly linear, to 320 mm long, to 1.2 mm wide, sparsely set with castaneous, unicellular fusiform hairs, fertile lamina with an apical fertile portion, to 1.6 mm long, midrib sulcate adaxially, convex abaxially; rachis recurved; segments pectinately arranged, up to 15 pairs, simple or forked once, longer towards the middle, to 8 mm long, to 0.6 mm wide, margins long-fimbriate, adaxially glabrous or sparsely set with unicellular hairs similar to those on the lamina, abaxially densely set with castaneous hairs, hairs unicellular, filiform, simple or irregularly branched, to 1.8 mm long. Sporangia in a single row on either side of the fertile segment costa, sessile, almost symmetric, ovoid or ellipsoid, with a subapical, uniseriate annulus. Spores brown, numerous, ellipsoidal to subglobose, monolete, foveolate, exospore to 95 µm long.
