Description:Genus Description - Plants of moderate size, in loose, rigid, dull, dark- or yellow-green to brown mats. Stems creeping, filiform, sharply acuminate leaves, irregularly branched. Branches ascending, curved or subcircinate when dry, frequently flagellateattenuate; paraphyllia none. Branch leaves erect-spreading or spreading when moist, ovate-lanceolate, gradually narrowed to an acute apex; margins irregularly and rather coarsely serrate in the upper 1/3 or more, recurved near the base; costa single, tapered and ± flexuose above, ending near the apex and sometimes nearly filling it or ending well below the apex; cells nearly uniform throughout, small (5-8 µm), short-oblong, oblong-rhombic, or subquadrate, smooth or minutely prorulose at back, thick-walled. Dioicous. Perichaetial leaves pale-yellowish, erect, subulate from a broader, sheathing base. Setae reddish; capsules symmetric, oval-cylindric (tapered at either end), brownish; annulus well developed; operculum conic, acute or rostrate; stomata present; exostome teeth pale, lance-linear, densely papillose or smooth above and variously striolate below; endostome pale, consisting of a rather well-developed basal membrane and stoutly linear segments. Calyptrae smooth, naked.
