Stems creeping to 50 mm long, with erect branches to 15 mm long, red-brown, with reddish rhizoids mostly near bases; central strand absent. Branch leaves erect- to wide-spreading when moist, scarcely altered when dry, ovate to lanceolate or lanceolate-oblong, 1.5–1.7 mm long, 0.56–0.92 mm wide, concave; apices acute, mucronate or obtuse; costa absent; margins entire, incurved near apices, without a border; apical cells elliptic, oblong to linear-rhomboidal, c. 24–34 μm long, c. 8 μm wide, smooth; midlaminal cells rhomboidal to linear-rhomboidal, 32–50 μm long, 6–8 μm wide, smooth; basal cells rectangular, c. 50 μm long, 6 μm wide; alar cells clearly differentiated, forming a basal band extending 5–8 cells toward apex, orange or red-brown, quadrate, becoming more rectangular near margin, c. 20 μm wide. Stem leaves sparse, ovate to oblong-lanceolate, 0.48–0.88 mm long, 0.21–0.49 mm wide; alar cells not as well developed. Perichaetial leaves linear to oblong-lanceolate, c. 10 mm long, c. 1.2 mm wide. Setae 3–12 mm long, reddish. Capsules shortly emergent, erect or suberect, cylindric, straight or asymmetric, c. 3 mm long, annulus non-revoluble, stomata absent. Calyptra cucullate, smooth.
