Plants medium sized, forming loose pendulous strands from mats, light green to golden- or reddish-brown. Primary stems short to ± long creeping, leaves usually eroded from stem. Secondary stems mostly pendent, irregularly branched; in cross-section outer cells (to 10 rows) small and thick-walled, inner cells larger, ± thin-walled, central strand weak; pseudoparaphyllia foliose. Leaves forming a multiple-morphic series, initially complanate, lateral leaves spreading to erect-spreading, median leaves loosely erect, oblong-lanceolate to lanceolate-subulate, 2.4-3.7 mm long, 0.6-0.9 mm wide, apex short to more typically long and slender acuminate, base clasping stem, weakly decurrent; margins erect to incurved, serrulate, usually sharply dentate near base; ecostate, or costate with a single weak costa; median cells linear, 70-120 µm long, 6-10 µm wide, ± thick-walled, unipapillose, papillae over cell lumen, indistinct (best observed on folded leaves); alar region somewhat well defined, cells subquadrate to short or long rectangular, 14-32 µm long, 10-16 µm wide, porose; distal stem leaves becoming slender and terete, often flagellate, leaves narrowly long lanceolate, concave, apex ending in a long capillary tip, secondary branches occasional, short, leaves then repeating inform that of initial leaf type. Dioicous. Sporophytes not observed.

 

Plantas medianas, matas formando hebras laxas péndulas, verde claras hasta dorado- o pardo-rojizas. Tallos primario cortos hasta ± largos, reptantes, hojas generalmente erosionadas desde el tallo. Tallos secundarios generalmente pendientes, irregularmente ramificados; en corte transversal células externas (unas 10 filas) pequeñas y con paredes gruesas, células internas mayores, paredes celulares ± delgadas, cordón central débil; pseudoparáfilos foliosos. Hojas formando series de formas múltiples, inicialmente complanadas, hojas laterales patentes hasta erecto-extendidas, hojas medias laxamente erectas, oblongo-lanceoladas hasta lanceolado-subuladas, 2.4-3.7 mm de largo, 0.6-0.9 mm de ancho, ápices acuminados cortos a más típicamente largos y delgados, base amplectante al tallo, débilmente decurrente; márgenes erectos hasta incurvados, serrulados, por lo general claramente dentados cerca de la base; ecostadas, o con costa simple y débil; células mediales lineales, 70-120 µm de largo, 6-10 µm de ancho, paredes ±  gruesas, unipapilosas, papilas sobre el lumen celular, no distinguibles (mejor observar en  hojas dobladas); región alar algo bien definida, células subcuadradas hasta corto- o largo-rectangulares, 14-32 µm de largo, 10-16 µm de ancho, porosas; hojas distales del tallo tornándose delgadas y teretes, a menudo flageladas, hojas angostamente largo lanceoladas, cóncavas, ápices terminando en un extremo largo capilar, ramas secundarias ocasionales, cortas, las hojas entonces se repiten volviendo al tipo inicial de hojas de la serie. Dioicas. Esporofitos no observados.
