Plants in loose tufts, yellow to yellowish green, glossy. Stems 2-8 cm, scarcely tomentose with whitish to reddish brown rhizoids. Leaves erect-spreading, sometimes nearly appressed, flexuose, little changed when dry, undulate or rugose, (3.5-)4-5.5(-6) × 1-1.5 mm, flat to ± concave proximally, subtubulose above, from a lanceolate base to a short, broadly acute apex, distal part of stem often with ovate, short-subulate, blunt leaves; margins serrate in the distal half; laminae 1-stratose; costa ending just before the apex, sometimes with two poorly developed toothed ridges above on abaxial surface, 1/13-1/8 the width of the leaves at base, row of guide cells, two thin stereid bands, adaxial epidermal layer of cells not differentiated, the abaxial layer with a few (usually 2) cells differentiated in distal part of the leaves; cell walls between lamina cells not bulging; leaf cells smooth; alar cells 2-stratose, well-differentiated, sometimes extending to costa; proximal laminal cells long, sinuose, pitted, (28-)47-71(-113) × (5-)9-11(-14) µm; distal laminal cells short-linear, sinuose, pitted, (25-)36-51(-73) × (5-)8-14(-20) µm. Sexual condition pseudomonoicous; dwarf males on rhizoids of female plants; interior perichaetial leaves abruptly long-acuminate, convolute-sheathing. Seta 2.5-3.5 cm, solitary, rarely two per perichaetium, yellowish brown to reddish brown. Capsule 2.5-3 mm, arcuate, inclined to horizontal, striate when dry, yellow-brown; operculum 1.7-3 mm.
