Plants small to medium to fairly robust, gray-green to bluish green to reddish brown with age, in loose tufts, often forming extensive patches. Stems (1–)4–5(–10) cm, simple, brownish tomentose only near the base. Leaves 3–6(–8) mm, densely imbricate, ± erect and almost straight when dry, erect-spreading to widely spreading when moist; sheath oblong-rectangular, yellowish, tapering to the blade; blade slender, bluish green and nitid, rather flat, with sharply infolded margins; marginal lamina 5–7 cells wide, 1-stratose, entire or minutely crenulate, membranous and transparent, enclosing the lamellae and overlapping towards the apex; costa usually somewhat toothed distally, excurrent, forming a subulate, toothed awn, the awn reddish brown throughout or slightly decolorate at tip; lamellae bluntly crenate in profile, 6–8 cells high, the marginal cells in cross-section ovate to pyriform, thick-walled, ending in a distinct knob, smooth or rarely faintly papillose, the marginal cells of lateral lamellae (enclosed by the overlapping margins) ovoid and less strongly thickened; sheath cells 70–100 × 6–10 µm, narrowly rectangular (4–6:1), narrower toward the margin; cells of the broad marginal lamina transversely elongate, very thick-walled. Sexual condition dioicous; perigonial rosettes yellowish to reddish green; perichaetial leaves longer than the foliage leaves, long-sheathing, the blade almost obsolete, ending in a slender yellowish or hyaline awn. Seta (1–)3–5 cm, stout, yellowish to reddish brown. Capsule 2.5–5 mm, rectangular, longer than wide (1.5–2:1), reddish brown to dark brown, glaucous when fresh, suberect, becoming horizontal when mature, sharply 4-angled and prismatic; peristome 200–240 µm, divided to 0.6–0.8, the teeth 64, keeled at back. Calyptra whitish to light brown, covering the capsule. Spores 6–10(–12) µm.
