Plants medium-sized, caespitose, dark green to blackish green; terricolous or saxicolous. Stems (5-)10-20 mm high, occasionally branching above. Leaves weakly appressed and curved dry, erect-spreading wet; linear-lanceolate to ovate-lanceolate, (2.0-)2.5-3.0 mm long; bistratose above base; apex cucullate; margins occasionally multistratose. Costa percurrent to subpercurrent, smooth dorsally and ventrally; in section bulging dorsally, guide cells 8, distinct, ventral stereid band 2 cells thick, ventral surface cells distinct, slightly smaller than laminal cells, dorsal stereid band 3 cells thick, dorsal surface cells small, outer wall generally more strongly thickened. Upper laminal cells rounded-quadrate or ± transversely rectangular, 5-7(-10) µm, thickened; basal cells distinct, rectangular, thin-walled, yellowish. Seta 2-3 mm long, yellow-brown. Capsule short-cylindrical, 1.2 mm long. Peristome teeth narrowly triangular, occasionally irregular, cleft, ornately papillose, yellowish. Operculum rostrate, 0.5 mm long.
