Plants large to rather robust, up to 7–8 cm long, yellowish green or brownish green above, brownish or dark brown below, in loose tufts. Stems creeping or ascending, usually irregularly, sometimes subpinnately branched; central strand absent. Leaves imbricately appressed when dry, erect-spreading when moist, clearly secund, 2.6–4.0 mm long, ovate-lanceolate to oblong-lanceolate, keeled above, with hyaline hair-points, the hair-points often flexuous, variable in length, dentate or nearly smooth; margins recurved on one side up to 1/2–3/4 the leaf length, nearly plane or slightly recurved on the other side, unistratose in cross section; costa thick at base, slender upward, percurrent or nearly so; upper and median leaf cells rectangular, 10–23 µm × 3–6 µm, sinuosely thick-walled, smooth; basal cells narrowly rectangular or linear, 23–50 µm × 5–7 µm, sinuosely thick-walled, smooth; alar cells differentiated, usually reddish brown, auriculate, consisting of 2–4 rows of enlarged, thin-walled, rectangular or subquadrate cells. Perichaetial leaves similar to upper stem leaves, but without hyaline hair-points. Setae erect, reddish brown, 10–12 mm long, often twisted above; capsules erect, oblong-ovoid to cylindrical, reddish brown, 2.0–2.7 mm long; opercula long-rostrate; annuli well developed, consisting of 2–3 rows of thick-walled cells; peristome teeth linear, reddish brown, divided to the base, densely papillose. Calyptrae cucullate. Spores small, ca. 12 µm in diameter.
