Yellow-green to brownish, wiry, delicate, plants in dense mats, in naked eye no leaf is seen except stem. Main stem creeping, irregularly, bipinnately branched, branches in one plane, up to 3cm long. Paraphyllia present, simple, filamentous. Leaves dimorphic, stem leaves incurved on drying, erect spreading when moist, larger in size and less in number, distant, triangular, ovate, suddenly narrowed into a long acumen from a cordate base, plicate, up to 8.0 mm long and 0.2 to 0.3 mm wide. Costa ceasing a little below the apex to percurrent. Branch leaves small, close, erect spreading (somewhat curled and appressed to stem when dry), concave, ovate, with acute point ±0.18 mm long and ±0.15 mm. wide, margin crenulate, flat, costa single, ceasing well below apex. Leaf cells small, obscure with one and more than one papillae, irregularly hexagonal, ±5 to 6 µm wide. Sporophyte on main stem, perichaetial leaf narrow with fine long floxuose acumen, into a denticulate arista, nerve excurrent, without papillae, cells irregularly rounded to rectangular. Seta erect, rough all over with papillae, ± 1.5 mm long, arcuate at top, dark brown in colour. Capsule horizontal, inclined, gibbous, ovate cylindrical, ± 1.5 mm long and ± 0.5 mm in diameter, yellow-brown in colour and mildly papillose. Peristome normal, hypnoid. Exostome teeth brownish, lanceolate, densely horizontally stripped below, ± 0.5 mm high, basal membrane high, endostome segments pale, keeled with median perforation slits almost as long as exostome. Cilia one or two, slightly shorter than endostome segments. Mouth cells short, irregularly rounded to quadrate, exothecial cells large, irregularly quadrate to rectangular in shape. Spores rounded dark brown in colour, ±10 to 15 µm in diameter.
