Plants medium-sized to large, up to 5(–8) cm high, green or yellowish green, with a grayish sheen when dry, in compact tufts. Stems erect or ascending, simple or branched, somewhat radiculose at base. Leaves 4–8 mm long, usually strongly falcate-secund, sometimes stiffly erect or fragile, linear-lanceolate, gradually narrowed to a subtubulose apex; margins plane below, slightly involute and serrulate above; costa broad, occupying ½ or more the leaf base width, filling nearly all of the subula, excurrent, 2–4 layers of thick-walled cells in transverse section, with the dorsal rows of green cells interspreading among the hyaline cells, forming longitudinal striations; laminal cells at the shoulder, elongate-rectangular to linear, sometimes porose; alar cells inflated, hyaline or brownish, usually extending close to the costa; asexual reproduction sometimes by means of fragile leaves. Setae straight, up to 1.5 cm long, reddish brown, twisted clockwise when dry; capsules erect, oblong-cylindric, 1–3 mm long, reddish brown to dark brown, irregularly furrowed when dry or empty; opercula long-rostrate, nearly as long as or slightly shorter than the urns; annuli none; stomata present; peristome teeth divided, ca. halfway down, reddish or brownish, usually perforate below, obliquely to vertically striolate to the apex. Spores 25–34 µm in diameter, finely papillose.
