Plants in green to golden-brown or darker brown mats; stems slender, to 

 .3 em long 1 , with leaves to 2 mm broad, prostrate ; lateral branches frequent, 

 5 mm or more apart, diverging at a wide angle, sometimes becoming flagelli- 

 f orm ; flagelliform branches numerous, long. Leaves approximate to imbricate, 

 ascendent, becoming strongly deflexed when dry, asymmetrically narrow-ovate 

 to oblong, 0.6-1.2 mm long. 0.12-0.5 mm broad at the base, narrowed to the 

 bidentate apex ; the teeth short, sharp, two to four cells high, two to four cells 

 broad at the base, the sinus lunulate.; leaf-cells large, thin-walled, the trigones 

 large, with convex sides, often becoming coalesced, the lumina angnlar-ronnded 

 to stellate, the cuticle faintly verruculose; cells of the apical region 20-36/* in 

 diameter, a vitta not differentiated. Underleaves distant to imbricate, rounded 

 to subquadrate, to 0.65 mm long and wide, the apex undulate to 4-lobed. Male 

 branches solitary, the bracts ovate, bidentate, the bracteoles smaller ; antheridia 

 occurring singly. Female branches solitary, the bracts and bracteoles ovate, 

 the intermediate and innermost series divided to one-third their length into 

 usually three lacineae. the lateral margins eiliate to dentate. Perianth-mouth 

 short-ciliate. Fig. 5. a-f. 



Habitat: On tree bases and logs, in mats or among other bryophytes.
