Plants typically robust, lustrous, golden brown to olive green, older parts sometimes dark brown to black, in complex festoons. Primary stems dark castaneous, irregularly branched, prostrate, at-tached tightly to substrate; stems in cross section with 4–6 rows of small, incrassate, pigmented cells, cortex of larger, thin-walled, hyaline (sometimes pigmented) cells, central strand absent; rhizoids smooth, castaneous, in clusters basal to dorsal side of fragile, appressed, acute to acuminate scale-like leaves. Secondary stems and branches densely foliate, irregularly branched, in complex festoons, to 30 cm long; paraphyllia none; pseudoparaphyllia foliose, obtuse; axillary hairs with 1–2 short, pig-mented basal cells and 2–5 elongate, hyaline distal cells, the terminal cells more or less obtuse. Sec-ondary stem and branch leaves erect-spreading, more or less unchanged when dry, distichous, equitant, conduplicate, more or less auriculate, cucullate, not retuse, pungent, strongly recurved, oblong-lanceolate, 1.4–4.0 X 1.2–1.8 mm; margins more or less entire, incurved distally; costae short, double, at times indistinct or ecostate; cells linear-repand, smooth, incrassate, porose, median cells 29–68 r m long, distal and auricular cells shorter; alar cells differentiated, in small clusters, dark castaneous, rounded-quadrate to oblong. Asexual propagula none. Dioicous. Perigonia and perichaetia gemmiform, axillary. Sporophytes not seen in Central American collections, description from Brazilian specimens. Setae short, 0.2–0.5 mm long, smooth, castaneous or yellow. Capsules immersed, erect, radially symmetric, ovate to cylindric, castaneous or yellow, 2.2–2.5 mm long; exothecial cells irregularly quadrate to ir-regularly oblong, thin- to medium-walled; stomata absent; opercula conic, short- to long-rostrate, 0.6–0.8 mm long; peristome diplolepideous, single, prostome present, fragmentary; exostome teeth in-serted just below capsule mouth, incurved when dry, erect when wet, pale, linear-triangular, more or less denticulate, median line and dorsal trabeculae faint, ventral trabeculae low; endostome absent. Spores anisosporous, 18–29 mm and 32–56 mm, smooth to faintly papillose. Calyptrae not seen, description from Lin (1983), small, 0.8–1.2 X 0.29–0.48 mm, cucullate or mitrate, entire at base, extending to the base of opercula, densely hairy, hairs filamentous, articulate, flexuose, smooth.
