    Species Description - Plants small, chain-like, whitish-green of yellow-green becoming red or rosy purple, in mats or creeping among other bryophytes. Stems slender, 1-2 cm long, with leaves to 0.4 mm wide, occasionally branched; branches lateral, of the Frullania type or ventral-intercalary, leafy, the ventral branches often short, bearing a female inflorescence. Rhizoids long, slender, colorless, from cells of the ventral side of the stem. Line of leaf insertion short, nearly transverse. Leaves broadly obovate, bilobed to one-half their length, concave with the outer part curved upward, imbricate, the segments long-triangular from a base 5-8 cells wide and ending in as erect or curved, uniseriate 5- to 7-celled tip, the dorsal margin convex from a straight base, the ventral margin with a large sac, the sinus usually broad V-shaped; cells of the leaf tip 30-39 X 13-20 µ, cells of the segment mostly quadrate, 20-25 µ, rarely to 30 X 20-25 µ, the walls uniformly thickened, without distinct trigones, the cuticle essentially smooth. Underleaves absent. Plants monoicous and dioicous. Male inflorescence terminal often becoming intercalary on a stem, long, the bracts in many series, equally bifid, without a sac on the ventral margin and without the long, capillary leaf-tips. Female inflorescence on a short ventral branch, the bracts and bracteoles in 3 series, long-ovate, keeled, bifid, the margins serrate. Perianth long, 3-keeled above, the mouth broad, truncate, spinose and short-ciliate. Gemmae spherical from the tips of leaves, rare.
