Leaves 5–6 mm long, somewhat flexuose when dry, erect-patent when moist, lanceolate, contracted at base, gradually narrowed to a canaliculate subula, ending in a subhyaline to occasionally hyaline hairpoint; margins inflexed in the upper 2/3, serrulate in the upper 1/3; costa pale yellowish brown, occupying ca. 1/3 the leaf base width, shortly excurrent, with dorsal and ventral stereid bands, sometimes the ventral stereid band not well defined in transverse section; upper cells obliquely rectangular to rhomboidal, ca. 30 µm × 10 µm, thick-walled, sometimes with 1 row of thin-walled, rectangular cells at the margins; basal cells yellowish, moderately long-rectangular, ca. 50 µm × 15 µm, narrower toward the margins; alar cells forming well marked auricles, moderately inflated, hyaline or reddish brown. Dioicous. Setae ca. 5 mm long, straight when dry, cygneous when moist, reddish brown; capsules erect, ovoid to short-cylindric, symmetric, scabrose at base; opercula long-rostrate; annuli compound, in 2 rows of cells; peristome teeth divided to the middle or lower, reddish and not vertically striate below.
