Plants rather small, forming loose tufts or thin mats, yellowish-green to golden. Primary stems apparently short creeping. Secondary stems subascending or spreading, equally foliate, leaves loosely erect, erect-spreading when wet. Leaves lanceolate, ca. 1.9-2 mm long, 0.5-0.7 mm wide, concave, partially plicate along costa, apex gradually to somewhat abruptly acuminate, acumen ± broad, often with a half twist; margins plane to partially reflexed on one or both sides, often strongly so below apex tip, entire or nearly so; costae double, ca. 1/2 lamina length or somewhat less; laminal cells appearing smooth and mostly thick-walled, upper and median cells oblong to rhomboidal, 20-40 µm long, 5-6 µm wide; basal cells irregular oblong-rectangular, those adjacent to costa appearing weakly porose, marginal cells at or near base forming a weak border of oblong-linear cells. Dioicous? Perichaetia lateral. Setae elongate, longer than 6 mm, distal 2/3-1/2 weakly scabrous or roughened. Capsules erect, urn ovoid, 1.2-1.3mm long; opercula not observed; peristome double, exostome teeth 16, spreading-recurved when wet, erect when dry, ca. 480 µm long, papillose and appearing bordered; endostome basal membrane appearing low, segments 16, papillose. Calyptrae and sporesnot observed.
Plantas algo pequeñas, formando manojos laxos o tapices ralos, verde-amarillentas a doradas. Tallos primarios aparentemente cortos, reptantes. Tallos secundarios subascendentes o extendidos, uniformemente foliados, hojas laxamente erectas, erecto-extendidas en húmedo. Hojas lanceoladas, aprox. 1.9-2 mm de largo, 0.5-0.7 mm de ancho, cóncavas, parcialmente plegadas a lo largo de la costa, ápice gradualmente a algo abruptamente acuminado, acumen ± ancho, generalmente semi-retorcido; márgenes planos a parcialmente reflexos sobre uno o ambos lados, generalmente fuertemente reflexos debajo del extremo del ápice, enteros o casi así; costa doble, aprox. 1/2 del largo de la lámina o algo menos; células de la lámina aparentemente lisas y generalmente de paredes gruesas, células superiores y mediales oblongas a romboidales, 20-40 µm de largo, 5-6 µm de ancho; células basales irregularmente oblongo-rectangulares, aquellas adyacentes a la costa aparentemente débilmente porosas, células marginales en, o cerca, de la base formando un borde débil de células oblongo-lineares. Dioicas? Periquecios laterales. Setas alargadas, mayores de 6 mm de largo, levemente escabrosas o rugosas en 2/3-1/2 distales. Cápsulas erectas, urna ovoide, 1.2-1.3 mm de largo; opérculo no observado; peristoma doble, dientes del exostoma 16, extendido-recurvados en húmedo, erectos en seco, aprox. 480 µm de largo, papilosos y aparentemente bordeados; membrana basal del endostoma aparentemente baja, segmentos 16, papilosos. Caliptra y esporasno observadas.
