Plants small, whitish-green to deeply pigmented with red-brown, often 

 etiolated, in deep tufts or among other bryophytes; stems 2-6 cm long, with 

 leaves to 0.5 mm broad, slender, irregularly bipinnately branched, the lateral 

 branches few to many, long, often branched, some becoming flagelliform in the 

 outer part, ventral intercalary branches long, slender, flagelliform, rarely leafy; 

 stem in transverse section averaging 0.4 mm across, the unistratose cortical 

 layer of 12 large, thin-walled cells 30x70 p., the cells of the medulla under 45 p, 

 the walls thin with very small trigones. Line of leaf insertion oblique, the leaves 

 incubous. Leaves distant to approximate, patent, rectangular in outline, to 

 0.5 mm long, 0.35 mm wide, the dorsal margin curved, longer than the ventral 

 margin, the cells in eight longitudinal rows from the base, the apex quadrifid; 

 segments (teeth) only two or three cells long, two cells wide at the base; leaf- 

 cells 40-45x30 p., the walls uniformly thickened, the cuticle faintly verruculose. 

 Underleaves similar to the leaves, large, only slightly shorter, appresscd or 

 spreading, of eight rows of cells, the segments obtuse, the base of two cells. Male 

 inflorescence on a short ventral sexual branch, catkin-like, the bracts and 

 bracteoles in few series. Female inflorescence and sporophyte not seen. PI. 46.

Habitat: Among Sphagnum, or in tufts in wet places.
