Plants small to medium-sized, lustrous, golden to yellowish green, in dense (occasionally loose) mats, at times pendent. Stems and branches complanate-foliate, 2–10 cm long, prostrate or erect-ascending, irregularly branched, at times long-attenuate, yellowish green when young, becoming red with age; stems in cross section with epidermis of 1–2 rows of small, thick-walled cells, cortical cells enlarged, thin-walled, central strand absent; paraphyllia and pseudoparaphyllia absent; rhizoids from small clusters of initials abaxial to the leaf insertions, papillose-roughened, reddish brown, not or sparsely and irregularly branched; axillary hairs 3–6 cells long, basal 2–3 cells short-rectangular, red-dish brown, upper 1–3 cells elongate, hyaline. Stem and branch leaves similar, 0.8–1.8 mm long, closely or somewhat distantly spaced, pseudodistichous, ovate to ovate-oblong, concave to asymmetrically conduplicate, abruptly ending in piliferous, recurved acumina, rounded to shortly auriculate at base; margins entire, incurved on one side at base and sometimes above; costae short and double, or absent; cells smooth, firm-walled, upper cells vermicular, 15–40 X 3–6 mm, median cells linear-flexuose, 60–100 X 2.5–4.0 mm; basal cells linear-oblong; alar cells undifferentiated. Asexual reproduction occasionally by uniseriate, rhizoidal gemmae. Dioicous. Sporophytes not known in Central America. Only one, immature and badly damaged sporophyte from Colombia (Cleef & Jaramillo-M 237, MO) seen, description from Lin (1984). Setae elongate, 9.5 mm long. Capsules inclined, oblong, apophy-ses absent, 1.6–1.7 mm long; exothecial cells quadrate to rectangular, medium-walled; stomata on neck; peristome double, hypnoid, prostome absent, exostome papillose, median line thin, dorsal tra-beculae thin, dorsal lamellae striate-papillose, ventral surface smooth; endostome not described. Spores rounded, 10–12 r m, densely papillose. Calyptra not described.
