Plants medium sized, in dense tufts, yellowish green or brown above, blackish below. Stems erect, 3-5.5 cm tall, few branched by innovations; in cross-section broadly 3-4 angled, epidermal cells usually small, thin to thick-walled, outer 1-2 rows of cortical cells somewhat small, thick-walled (angular stem corners with 3-4 rows), progressively larger and thin-walled, central strand present; sparingly to densely tomentose below, rhizoids rusty-red, papillose, rather fragile, appearing blackish. Leaves erect-spreading to spreading from a short sheathing base, evenly and densely foliate, lanceolate to ovate- or oblong-lanceolate, 1.8-2.5 mm long, to 0.6 mm wide, ± broadly acute to somewhat obtuse-acute, rarely subacuminate, base decurrent; margins plane or reflexed to recurved from base to mid-leaf or just beyond, entire or weakly dentate at apex; costae single, strong below, subpercurrent to percurrent, in cross-section epidermal cells rather large, inner cells thick-walled; laminal cells unistratose, smooth, ± thick-walled, median and upper cells irregularly short rectangular, 22-45 µm long, 10-15 µm wide; lower and basal cells long rectangular, 70-100 µm long, 18-22 µm wide, lax, thin-walled; alar region undifferentiated. Synoicous. Perichaetia terminal; leaves elongate and enlarged, to 4 mm long, base often reddish; paraphyses elongate clavate. Setae single, very much elongate, pale to dark yellowish-red or orange, to 8 cm long, slender and wiry, smooth. Capsules suberect, urn rather long pyriform, 2-2.5 mm long, curved, asymmetric; annuli weakly differentiated; opercula bluntly conic; peristome double, exostome teeth 16, reduced, papillose, endostome well developed, smooth, basal membrane high, segments 16, cilia reduced. Calyptrae cucullate, 3-3.7 mm long, smooth and naked. Spores spherical, lightly papillose.
 
Plantas medianas, en manojo densos, verde amarillentas o pardas encima, negruzcas abajo. Tallos erectos, 3-5.5 cm de alto, poco ramificados por innovaciones; en corte transversal ampliamente 3-4 angulados, células epidérmico generalmente pequeñas, con pared delgadas a gruesas, 1-2 filas externas de células corticales algo pequeñas, celulas con paredes gruesas (3-4 filas en las esquinas del tallo anguloso), progresivamente mayores y con paredes delgadas, cordón central presente; escasamente a densamente tomentoso abajo, rizoides rojo-oxidados, papilosos, bastante frágiles, de apariencia negruzca. Hojas erecto-extendidas a patentes desde una base envainadora corta, dispuestas densa y uniformemente, lanceoladas a ovado- u oblongo-lanceoladas, 1.8-2.5 mm de largo, hasta 0.6 mm de ancho, ± ampliamente agudas a algo obtuso-agudo, rara vez subacuminadas, base decurrente; márgenes planos o reflexos a recurvados desde la base hasta el centro de la hoja o un poco más allá, enteras o débilmente dentado en el ápice; costa simple, fuerte abajo, subpercurrente a percurrente, en corte transversal células epidérmicas bastante grandes, células internas con paredesgruesas; células de la lámina uniestratificadas, lisas, paredes ± gruesas, células mediales y superiores irregularmente corto rectangulares, 22-45 µm de largo, 10-15 µm de ancho; células inferiores y basales largas y rectangulares, 70-100 µm de largo, 18-22 µm de ancho, laxas, con paredes delgadas; región alar indiferenciada. Sinoicas. Periquecios terminales; hojas alargadas y agrandadas, hasta 4 mm de largo, bases a menudo rojizas; parafisos claviformes alargados. Setas simples, muy alargadas, de color rojo-amarillento pálido a oscuro o naranja, hasta 8 cm de largo, delgadas, alambrinas y lisas. Cápsulas suberectas, urna bastante largo piriforme, 2-2.5 mm de largo, curvadas, asimétricas; anillo débilmente diferenciado; opérculo obtusamente cónico; peristoma doble, exostoma con 16 dientes, reducidos, papilosos, endostoma bien desarrollado, liso, membrana basal alta, 16 segmentos, cilios reducidos.
