Plants small to medium-sized, in loose or usually dense mats or tufts, green, yellowish or brownish green to olivaceous in the upper part, darker brown to blackish brown or blackish proximally. Stems (1-)1.5-4.5(-6) cm, prostrate to erect-ascending, usually much subpinnately branched to sparsely branched. Leaves loosely imbricate when dry, erect-spreading to recurved when moist, straight to secund, ovate-lanceolate to lanceolate, keeled distally, narrowly canaliculate proximally, (1.5-)1.7-2.4(-2.6) × 0.5-0.7 mm; margins narrowly recurved to revolute on both sides to near the apex, distinctly wavy to lumpy, 2-stratose for 1-3(-4) cells rows in the distal half, sometimes largely 1-stratose or with 3-stratose patches, largely 1-stratose in the proximal half with 2-stratose spots for 1(-2) cell rows or rarely predominantly 2-stratose; apices acuminate, often muticous or terminated with a short, to 0.5 mm, stout, hyaline, sharply serrate awn, not or hardly decurrent; costa percurrent or excurrent into the awn, strongly convex on the abaxial side, 50-80 µm wide basally, 35-45 µm wide distally, 3(-4)-stratose near the base, with 3-5 adaxial cells, 2-3-stratose in the middle and 2-stratose near the apex with 2-3 adaxial cells; laminal cells 1-stratose smooth or pseudopapillose; basal laminal cells short-to long-rectangular, 15-45 × 7-8 µm moderately thick-walled, sinuose-nodulose; alar cells slightly differentiated, yellowish; supra-alar cells (2-8) often not weakly sinuose, somewhat thick-walled, not forming a basal marginal border; medial and distal laminal cells irregularly isodiametric to rectangular, 5-20 × 7-9 µm. Inner perichaetial leaves strongly differentiated, ovate, narrowly obtuse to subacute at the apex, hyaline throughout. Seta dark red to reddish brown, (3-)6-8 mm. Capsule brown, ovoid, obloid to short-cylindric, (1.2-)1.5-2 × 0.4-0.6 mm, smooth; operculum long-beaked, to 1 mm; peristome teeth 180-200 µm, yellowish brown, papillose, deeply divided into 2-3 irregular prongs arising from a basal membrane, 35-50 µm high. Spores 10-18 µm.
