Stems branched, yellow, densely tomentose with red-brown rhizoids throughout, not concealed by leaves. Leaves spreading or somewhat recurved when moist, crisped, flexuose and loosely curled around stem when dry, lanceolate or linear-lanceolate, 1.1–3 mm long, 0.3–0.5 mm wide, undulate; apex acute; base slightly decurrent; costa ending below apex or rarely percurrent and broadened at apex; margin ±undulate, often dentate, with teeth formed by whole cells, without a border; laminal cells in apical half rounded-hexagonal, isodiametric, 6–15 μm long, 4.5–15 μm wide, with 3–6 papillae per cell; basal laminal cells rectangular, 15–95 μm long, 5–13 μm wide, hyaline, smooth, gradually transitioning to shorter papillose cells close to base. Perichaetial leaves ovate-lanceolate, with acuminate apices. Setae 5–15 mm long, yellow, smooth, twisted anticlockwise. Capsules erect, oblong or cylindric, 1.4–2 mm long, straight, yellow or light brown, with 8 deep ribs along length when dry. Peristome single; endostome segments 8, rarely 16.
