Leaves often crispate when dry, imbricate or slightly falcate-secund when moist, lanceolate, gradually or rather abruptly narrowed from an oblong-ovate base to a slender, channeled acumen; margins plane, entire below, minutely serrulate at the apex; costa stout, occupying 1/5–1/4 the leaf base width, excurrent into a slender point, mammillose at the back; upper cells rounded quadrate to short-rectangular, thick-walled, not porose, sometimes mammillose at the back of leaves; basal cells elongate, rectangular, faintly porose; alar cells quadrate, inflated, unistratose, brownish. Dioicous. Perichaetial leaves with a high convolute-sheathing base, abruptly narrowed to a short, subulate apex, papillose at the tips. Setae single, straight, yellowish green, 1.0–1.2 cm long; capsules erect, oblong-ovoid to short-cylindrical, symmetric; exothecial cells rectangular, thick-walled; opercula erect, conic-rostrate, nearly as long as the urns; annuli in 1 row of large cells; peristome teeth lanceolate, ca. 2.3 mm long, divided to the middle, papillose at the tips, vertically striolate at the base.
