Plants medium-sized to large, forming mats, dark green to yellow-green or sometimes tinted red-brown; corticolous. Stems creeping, 20-40 mm long, branching irregular; in section round, central strand absent, inner cortical cells thin-walled, hyaline, in 4 rows, outer cortical cells smaller, thick-walled, yellow, in 3 rows, epidermis of enlarged thin-walled cells fragile. Leaves somewhat distant but evenly spaced, wide-spreading wet, spreading and narrowed dry, somewhat falcate; oblong to elliptical, 2.0-3.2 mm long; acuminate; narrowed to insertion; margins plane, serrate, not bordered. Costa short and double or double and extending to midleaf, smooth; in section a small group of cells bulging dorsally. Upper laminal cells rhomboidal, homogeneous, 66-112 µm long, 15-22 µm wide, walls thin to weakly thickened, smooth; basal cells quadrate to short rectangular at attachment, 15-20 µm long, hyaline, walls thin, smooth; alar cells not differentiated. Gemmae on stem, in small tufts, cylindrical, to 250 µm, green, smooth. Autoicous. Perichaetia not obvious; perichaetial leaves lanceolate-acuminate, 1.5-2.2 mm long, leaf cells fusiform. Seta 2-6 mm long, brown, papillose. Capsule exserted, ± erect, ellipsoid, 1 mm long, smooth, yellow-green, mouth red; urn ellipsoidal; neck shorter than urn; exothecial cells quadrate to rectangular, walls weakly collenchymatous, cells at mouth quadrate to transversely rectangular, neck cells quadrate; stomata on neck, phaneropore. Peristome double, red-brown; exostome teeth lanceolate, inflexed dry, erect appressed wet, striate with broad median furrow below, essentially smooth above, 500 µm high; endostome segments lanceolate and keeled above low basal membrane, as long as teeth, granulate; cilia absent. Operculum rostrate, 0.5 mm long. Calyptra mitrate, to 2 mm long, smooth. Spores rounded, 22-25 µm, granulate, light brown.
