Bih. Kongl. Svenska Vetensk.-Akad. Handl. 6(19): 22. 1882.
 
Plants small, bud-like, greenish brown to brown, or reddish brown when old, in gregarious or scattered thin tufts. Stems very short, simple, seldom irregularly branched; central strand not differentiated or poorly developed. Leaves thick, fleshy, but rigid, usually incurved or slightly tubulose when dry, erect or erect-spreading when moist, ovate or broadly ellipsoid to ligulate, upper lamina deeply channeled, cucullate or rounded at the apex, with concave and broad, clearly sheathing hyaline base; margins entire to subentire, strongly inflexed, marginal cells usually hyaline in several rows, forming a broad, indistinct border extending well above shoulders; costa flat and broad, subpercurrent to percurrent, or sometimes long-excurrent as a smooth or serrate awn, ventrally bearing many green, branched filaments from midleaf to the leaf apex, the filaments with terminal cells enlarged and thick-walled; lower leaf cells oblong, hyaline, thin-walled near costa, quadrate, thick-walled near shoulders; upper cells bistratose on both sides of costa, transversely irregularly rectangular or rhomboidal, thick-walled, smooth, green. Dioicous or monoicous. Perichaetial leaves not much differentiated from stem leaves, only slightly larger. Setae elongate, slender, reddish brown or purple; capsules erect, cylindric or narrowly oblong-ovoid, more or less symmetrical; annuli differentiated, usually persistent; peristome teeth 16, split into 32 long, filiform divisions, twisted in 1 or more counterclockwise spirals, densely papillose; basal membrane low; opercula mostly obliquely rostrate. Calyptrae cucullate, smooth. Spores small, yellowish green, mostly smooth, rarely papillose.
