Stems 3-22 mm tall, frequently branching by subperichaetial innovations, innovations to 14 mm long, occasionally tomentose below; rhizoids red-brown, coarsely papillose; tubers rare, 200-760 µm, reddish brown or yellowish brown. Leaves comose, frequently semi-rosulate, frequently in successive comal tufts, distant and smaller to reduced below, appressed to erect or occasionally twisted dry, erect-spreading to widely spreading wet; broadly ovate to oblong, obovate-oblong or obovate, (1,7-)2.0-4.0(-6.0) mm long; apex acute to infrequently obtuse; lamina infrequently inflexed above; margins plane above, plane to recurved in lower 1/2 to 2/3, entire to crenulate or denticulate above; border absent or indistinct. Costa strong, aristate, awn 100-240 µm long, smooth to occasionally denticulate above, occasionally yellowish or reddish below; in section subround to round, ventral surface cells present, dorsal stereid band strong, stereids in 3-4 rows, dorsal surface cells incrassate to sub-stereid, hydroids present between guide cells and stereid band, upper laminal cells rhomboidal, occasionally pitted, frequently incrassate, frequently gradually narrowed towards margin, (35-)45-80(-100) µm long, (11-)12-20(-22) µm wide; basal cells rectangular to quadrate, pitted, occasionally yellow below. Dioicous, frequently with sporophytes. Perichaetia terminal; leaves narrowly oblong-lanceolate to triangular, 1-3 mm long, costa aristate.
