Stems branching by innovation in fertile stems, 7–25 mm long, red-brown, tomentose with brown to reddish brown rhizoids toward base. Leaves erect-spreading when moist, shrunken and twisted, and spirally twisted around stem when dry, obovate-spathulate, to 3 mm long, plane or concave; apex short-acuminate; costa percurrent or excurrent; hairpoint straight or bent, ± denticulate; margin usually finely serrulate or occasionally serrate toward apex, recurved at least in basal half, with 2–4 rows of longer and narrower cells forming a distinct border; laminal cells in apical half hexagonal or rhomboidal-hexagonal, 35–50 μm long, 15–25 μm wide; basal laminal cells long-rectangular. Seta 20–30 mm long, reddish. Capsules horizontal to pendent, cylindric to pyriform, 1.5–3 mm long, pale brown to brown. Operculum low-conic.
