Plants medium-sized to fairly large, rather slender, loosely caespitose or forming extensive patches, dull green to yellowish or blackish in the upper part, brownish or blackish brown proximally, sometimes hoary. Stems 5-7 cm, erect to decumbent, sparsely or profusely subpinnately branched, rarely quite unbranched. Leaves loosely appressed, straight or secund when dry, erect-spreading to spreading when moist, lanceolate, channeled along the costa, (1.7-)2.3-3.2(-4) (with a hair-point) × 0.5-0.8 mm; margins entire, smooth or somewhat wavy in the distal half, recurved to revolute on both sides to the apex, 1-stratose distally or with 2-stratose patches, seldom predominantly 2-stratose near the apex in 1 cell row; epilose or piliferous, awns erect-flexuous, more yellowish than whitish, flattened, (0.1-)0.5-1.1 mm, low-denticulate at the margins and occasionally spinulose at the abaxial side, usually not or slightly decurrent; costa percurrent or shortly excurrent into the awn, prominently convex abaxially, 80-100(-110) µm wide at the base, 60-70 µm wide distally, 3-4-stratose with 5-7 adaxial cells in the proximal portion, 3-stratose in the middle with 3-4 adaxial cells and 2-3-stratose distally with 2-3 cells on the adaxial side; laminal cells 1-stratose, not or slightly bulging on both adaxial and abaxial sides; basal laminal cells elongate, 15-35 × 7-10 µm, with thick and sinuose-nodulose walls; alar cells usually slightly differentiated, yellowish, sometimes forming a small, auriculate group of wider cells; supra-alar cells undifferentiated, not forming a marginal border; upper and medial laminal cells rectangular to isodiametric, 10-25 × 7-10 µm. Inner perichaetial leaves ovate, hyaline, epilose. Seta brown, 4-10 mm. Capsule brown, somewhat lustrous, shortly cylindric, rarely obloid or ovoid, 1.5-3.2 × 0.6-0.8 mm; operculum long-rostrate, to 1.5 mm; peristome teeth 200-400 µm, reddish brown, papillose, mostly discontinuously divided into 2 prongs by median perforations, arising from a low basal membrane, to 30 µm high. Spores 12-20 µm.
