Plants: densely tufted, light to dark green, dull. Stems: 0.5–3 cm, erect, forked, with central strand, with rhizoids confined to base of stems and firmly affixed to substratum. Leaves: lanceolate, flexuose, crisped or curled when dry, 1–3.5 mm; costa single, subpercurrent, narrow; margins plane to incurved or recurved, 1- or 2-stratose; proximal cells elongate, 15–30 µm, smooth; alar cells with a few enlarged cells on margins, often colored or undifferentiated; distal cells subquadrate 7–10 µm wide, smooth or with longitudinal cuticular ridges. : Specialized asexual reproduction sometimes present, multicellular, on abaxial surface, elliptic to short-linear, of 4–10 cells, 1-seriate or with occasional 2-seriate portions, smooth. Sexual: condition autoicous; pergonial leaves abruptly narrowed to a long or short subula; perichaetial leaves variable, resembling vegetative leaves or broadly obtuse to acute or short-acuminate. Seta: solitary, yellowish, 3–15 mm, smooth. Capsule: light to dark brown when mature, elliptic to short-cylindric, 0.5–2 mm, smooth to longitudinally wrinkled when dry; annulus present, of 1–3 rows of cells, deciduous or absent; operculum rostrate, beak straight or oblique; peristome single, 16 teeth inserted below darkened cells of mouth, teeth entire to divided at apices, red-brown with hyaline tips.
