Leaves caespitose, up to 7 mm long, crispate when dry, falcate-secund when moist, lanceolate from a broad base to a long, subulate acumen; margins plane, entire below, double-toothed and bistratose above; costa thick, occupying 1/5 the leaf base width, shortly excurrent, ending in a short hairpoint, strongly papillose or serrate at back above; upper cells quadrate to short-rhomboidal, thick-walled, smooth; basal cells elongate, rectangular, porose; alar cells quadrate, incrassate, bistratose, yellowish brown. Dioicous. Male plants dwarfed. Inner perichaetial leaves high convolute-sheathing at base, suddenly narrowed to a short, setaceous subula. Setae single, elongate, straight, ca. 2 cm long, yellowish; capsules erect, cylindric, ca. 3.5 mm long, yellowish brown; exothecial cells short-rectangular; opercula erectly long-rostrate; annuli in 2 rows of large cells, deciduous; peristome teeth 2–3 divided, nearly to the middle, scarcely papillose at the tips, clearly transverse-barred, vertical striation indistinct below.
