Plants very variable in size, small to robust, dull green or brownish green, reddish with age, in loose or compact tufts. Stems (1-)4-6(-14) cm, densely leafy above, often leafless and thread-like below, simple or sparingly to fasciculately branched. Leaves (4-)5-8(-19) mm, loosely to densely imbricate, erect-spreading and subtubulose when dry, erect-spreading to widely spreading when moist; sheath ± nitid, elliptic to obovate, with tapering shoulders (in var. fragile contracted above the sheath and the blade caducous), broadly hyaline-margined; blade linear-lanceolate, the apex narrowly acute to finely acuminate; marginal lamina 2-5 cells wide, erect, coarsely serrate with multicellular teeth, distantly serrulate to subentire; costa excurrent, ending in a short, brownish, toothed awn; lamellae 5-8 cells high, entire in profile, the marginal cells with the free wall appearing greatly thickened, the marginal cells in section enlarged, yellowish to dark brown, ovate to narrowly ovate, the lateral walls strongly thickened, the lumen narrowly pentagonal and pointed at the apex, coarsely papillose; median cells of sheath 40-60(-80) × 6-12 µm, elongate-rectangular, thin-walled; cells of the marginal lamina 10-15 µm, subquadrate, sometimes transversely elongate; perichaetial leaves scarcely longer than the stem leaves. Seta (1-)3-5 cm, brownish. Capsule various, (1.5-)3-5(-8) mm, terete, narrowly cylindric to oblong-cylindric and curved, ovate-cylindric, or ovoid to almost spherical, suberect to inclined to almost horizontal; hypophysis tapering, rugose, with numerous conspicuous stomata in a broad basal band; exothecial cells irregularly rectangular, not bulging or mammillose, thin spots absent, rather thick-walled; peristome 600 µm (teeth 150-250 µm), divided to 0.6-0.75, the teeth 45-50, with some teeth irregularly developed and unequal, pale to somewhat darker in the median line. Spores 14-20 µm.
