Fairly strong, autoecious, yellowish, shining, stramineous, usually on stones, not much-branched; the prostrate branches pinnate, with rather small-leaved branches; the erect branches dichotomously or irregularly few-branched, strong, terete through imbricate leaves when dry, but with leaves spreading when moist; larger leaves 1.5 mm long, narrowly ovate-lanceolate, deeply concave to near the rather reflexed, usually oblique point, erect or subsecund when dry, imbricate-cochleate, faintly plicate or not plicate, all the leaves on some branches sometimes serrulate. Nerve wide below, faint above, often extending to the subula; margin erect or slightly reflexed, almost entire; cells shortly linear, 70 µ long, pellucid, often twisted, seldom pointed, the apical cells rather shorter, the basal cells shorter, and the pellucid alar cells quadrate, forming a cavity. Per. leaves wider, sheathing, shorter, more ovate, with long narrow subula, arched backward, laxly reticulated, almost entire, and almost nerveless. Seta 2-3 cm long, red, the upper half rough; capsule inclined, brown, oval-oblong, with high back and short neck; ring narrow; lid shortly conical; calyptra cylindrical; peristome as in B. implicatum.
