Plants large, in thick mats, green. Stems 6-8+ cm, 1-1.8 mm thick when dry, somewhat branched, primary branches erect-ascending to arcuate; central strand cells not differentiated; pseudoparaphyllia absent; rhizoids few. Branch leaves erect when dry, secund, somewhat flexuose, spreading to reflexed when moist, oblong-ligulate, 2.2-4 mm; base broadly decurrent; margins plane, entire; apex obtuse, rounded, or sometimes acute, intact; costa strong, ending sharply before apex, occasionally obscured by laminal cells distally, rarely asymmetrically 2-fid at end, pellucid, lighter green, abaxial costa cells papillose, papillae thick, in rows; basal laminal cells hyaline, papilla 1, region barely extending beyond 1/4 length of leaf base; medial and distal cells hexagonal, 8-12 µm, papillae many, branched. Perichaetia borne distally from last branching points, leaves similar to vegetative leaves, costa ending closer to apex, laminal cells papillose. [Seta 1-2 cm. Capsule long-elliptic, urn (1.7-)2-3.1(-3.3) mm; stomata absent; annulus well differentiated; operculum obliquely rostrate, 0.7-1 mm; exostome teeth irregular, 0.3-0.5 mm, nearly smooth, faintly striolate, not trabeculate, papillae inconspicuous toward apex; endostome basal membrane 2-4 cells high, segments moderately developed. Spores very variable in diam. between capsules, in some (19-)20-23(-25) µm, in others 15-16 µm, densely papillose].
