Lower leaves distant, upper leaves crowded, 2.5–4 mm long, spirally twisted to spreading flexuose when dry, erect‑spreading when wet, oblong to broadly spathulate, long-decurrent; apices acuminate; margins recurved in lower ½, indistinctly bordered by 2–4 rows of narrower, longer, somewhat thick‑walled cells, serrate above; costae percurrent to shortly excurrent; upper cells rhomboidal‑hexagonal, thin‑walled, 30–50 μm long, basal cells broadly rectangular, thin‑walled, lax, 40–80 μm long. Sporophytes not known from Central America. Pseudautoicous; male plants 1–2 mm high, on the tomentum of female stems. Setae 2 cm long. Capsules pendulous, oblong‑pyriform, neck short and slender; opercula nearly hemispheric, apiculate; endostome with a low basal membrane, narrowly perforate segments, and well‑developed, appendiculate cilia.
