Plants 3-10 mm, perennial, in dense short turfs, pale-green to yellow-green. Stems branched by several innovations from axils of stem leaves or outer perichaetial leaves, often becoming prostrate with age. Stem leaves erect-spreading, lanceolate to ovate-lanceolate, acuminate, 0.7-1.5 mm, becoming reduced proximally; costa percurrent to slightly excurrent; laminal margins smooth, weakly recurved; median and distal laminal cells rhomboidal to hexagonal, 3-4:1, 35-70 × 12-18 µm, proximal cells rectangular, 2-4:1, 40-70 × 18-24 µm, short-rectangular to quadrate in alar region in 2-6 rows extending 7-15 cells along proximal laminal margin; leaves of innovations similar to distal stem leaves except being smaller, gradually reduced proximally. Perichaetial leaves larger, 1.5-3 mm, elongate-triangular, lanceolate or ovate-lanceolate, gradually acuminate; costa percurrent to short-excurrent; laminal margins smooth, weakly recurved distally; median and distal laminal cells uniformly rhomboid to hexagonal, 3-7:1, 35-130 × 15-28 µm, proximal cells rectangular, 4-6:1, 70-140 × 15-28 µm, sometimes hyaline in alar region but cells not strongly differentiated. Specialized asexual reproduction absent. Sexual condition autoicous, antheridia terminating axillary leaf buds. Capsule terminal, 450-700 µm. Spores typically 20(8-36) per capsule, triangular to rounded-polyhedral, 140-250 µm, smooth to granulose, yellow.
