Plants medium-sized, slender, in tufts, light green to yellow-green; saxicolous. Stems 10-15 mm high, branching above, weakly radiculose below; in section sub-triangular, central strand small, inner cortical cells in 2-3 rows, varying in size, thin-walled, outer cortical cells in 2 rows, stereids, dark red. Leaves tristichous, rigidly appressed wet or dry, small and distant below, larger and crowded above; linear to narrowly triangular, 0.8-1.2 mm long, ventral surface broadly channelled to keeled; apex acute; base sheathing stem; margins erect, entire. Costa percurrent, superficial cells linear, smooth; in section ventrally concave, guide cells 12-16, exposed ventrally, incrassate, smooth, dorsal stereid band 1(-2) cells thick across costa, dorsal surface cells slightly larger, strongly incrassate, smooth. Upper laminal cells linear, incrassate, smooth; basal cells similar, weakly thickened, reddish yellow at insertion. Gonioautoicous. Perigonia gemmate, axillary on upper stem; leaves oval-acuminate, 0.6-0.7 mm long. Perichaetia terminal; leaves convolute, oblong-subulate, 1.2 mm long; costa filling subula. Seta erect to somewhat curved dry, 4 mm long, yellow to brownish; capsules erect to curved, ± asymmetrical, 1.5 mm long, smooth, brownish; exothecial cells thickened; stomata not seen; annulus revoluble; peristome absent; operculum obliquely rostrate, 0.5 mm high, cells not twisted; calyptra cucullate, small; spores round, 20-25 µm, coarsely papillose, brownish.
