Plants small and slender, pale-green to yellowish-brown. Stem cortex 1-layered, with few to numerous cells uniporose at the upper ends. Stem leaves elliptic to oblong, 1.2-1.8 mm, apex rounded, somewhat concave; hyaline cells fibrillose throughout, undivided, on the outer surface with many commissural pores in ± continuous rows, on the inner surface pores absent or occasional with a single and small corner pore. Branches stout, in fascicales of 2, both spreading, or 3 with 1 pendent, retort cells with inconspicuous necks. Branch leaves erect (not secund), broadly ovate to elliptic, 1-1.4 mm, concave, apex rounded-obtuse, narrowly bordered; hyaline cells on the outer surface with many rounded to elliptic pores in ± continuous commissural rows with occasional connecting fibrils, on the inner surface with pores absent or occasionally single and small at side corners; in cross-section green cells narrowly rectangular, exposed equally on both surfaces by thickened end walls, somewhat more on the inner; hyaline cells ± convex on both surfaces. Crum & Buck 1988.

Plantas pequeñas y delgadas, verde pálido a marrón-amarillento. Tallo con corteza uniestratificada, con pocas a numerosos células uniporosas en los extremos superiores. Hojas del tallo elípticas a oblongas, 1.2-1.8 mm, ápice redondeado, algo cóncavo; fibrillas a lo largo de las células hialinas, no divididas, muchos poros en filas ± continuas en la superficie externa de la comisura, superficie interna de la comisura sin poros o en ocasiones con un solo poro angular pequeño. Ramas robustas, en fascículos de 2 ramitas patentes, o 3 con 1 pendiente, células lageniformes con cuellos no conspicuos. Hojas de las ramas erectas (no secundas), anchamente ovadas a elípticas, 1-1.4 mm, cóncavas, ápice redondeado-obtuso, borde angosto; células hialinas en la superficie externa de la comisura con muchos poros redondeados a elípticos en filas± continuas, eventualmente con fibrillas conectivas, superficie interna sin poros u ocasionalmente con poros simples y pequeños en los ángulos laterales; células verdes angostamente rectangulares en corte transversal, expuestas de la misma manera en ambas superficies por las paredes engrosadas en los extremos, algo más en la superficie interna; células hialinas ± convexas en ambas superficies.
