Stems with branches horizontal, somewhat flattened, simple; epidermal cells in 2–4 rows, walls thick, inner cells larger, walls thick, central strand cell walls thin. Leaves somewhat contorted when dry, plane, sometimes falcate-secund; ventral branch leaves ovate to oblong-ovate, 1.1 mm; apex apiculate to acuminate; alar cells not or slightly differentiated; basal laminal cells more elongate than distal cells; distal cells lax, hexagonal to oblong-rhomboidal, 2.5–5:1, walls thick to thin; dorsal and lateral branch leaves ovate, broadly oblong-ovate, or ovate-lanceolate, 1.1 mm; apex acute to acuminate; basal laminal cells more elongate than distal cells; distal cells hexagonal, oblong-hexagonal to somewhat rhomboidal, 2.3–4.1:1, walls usually thick; marginal cells noticeably narrower. Seta 1.3–2.1 cm, flexuose, curved just below capsule. Capsule 0.9 mm; exothecial cells quadrate to rectangular, walls thin, often collenchymatous; stomata at extreme base of capsule; exostome teeth brown.
