Plants slender, light yellowish green, somewhat glossy, in loose mats. Primary stems creeping; secondary stems more than 10 cm long, attached to substrate at the base, pendulous above, sometimes flagelliform, irregularly pinnately branched; branches 1–2 cm long, obtuse or attenuate at the apex; in stem cross section epidermis consisting of 3 layers of small, thick-walled cells, and 7–8 layers of large, thin-walled medullary cells; central strand present. Stem leaves oblong or narrowly ovate at the base, strongly concave, ca. 2.0 mm × ca. 0.6 mm, rather abruptly shortly acuminate, or gradually narrowed to a slender apex, to ca. 1/3 the leaf length or more; margins finely serrulate above; costae very short, double or absent; median leaf cells linear, 60–70 µm × 4–5 µm, thin-walled to moderately thick-walled, smooth; alar cells weakly differentiated, quadrate or rectangular, strongly thick-walled; branch leaves moderately concave to plane, ovate-lanceolate, gradually long-acuminate at the apex. Phyllodioicous. Inner perichaetial leaves sheathing at the base, long-acuminate at the apex; costae absent. Setae 3–4 mm long, yellowish brown, smooth; capsules erect or suberect, ovoid or oblong-ovoid; opercula conic, obliquely short-rostrate; peristome double; exostome teeth narrowly lanceolate, hyaline above, finely papillose; endostome segments linear, shorter than the teeth, keeled, perforate, finely papillose; basal membrane low; cilia absent. Calyptrae cucullate, not hairy. Spores spherical, 12–20 µm in diameter, finely papillose.
