Plants of medium size or larger, pale green to greenish-brown, in loose mats 

 or scattered among other bryophytes; stems 5-10 cm long, with leaves to 1.2 mm 

 wide, prostrate to ascending, irregularly pinnate to bipinnate, the branches mostly 

 3 mm apart, to 1 cm or more long becoming flagelliform at the tips, ventral 

 flagelliform branches occasional. The line of leaf insertion oblique. Stem leaves 

 distant to subimbricate, ovate-truncate, 0.4-0.6 mm long, 0.7 mm broad at the 

 base, concave, quadrifid to less than one-third ; segments short, broadly triangular 

 from a 3- to 4-celled base, acute, incurved ; leaf cells at the base of the segments 

 18-24 x 18 ix, the walls scarcely thickened, the lumina rounded, the cuticle smooth. 

 Stem underleaves quadrate to longer than broad, not as wide as the stem, concave, 

 0.5 mm broad at the base, quadrifid to one-third or one-half, the segments 

 triangular from a 3- to 5-celled base, the apex broad, blunt or acute. Branch 

 leaves and underleaves much larger, with the segments often shorter and blunt. 

 Plants dioicous. Male inflorescence with bracts and bracteoles in 6 or more series, 

 the bracts concave, bifid to one-fifth, the segments acuminate; antheridia solitary, 

 very large. Female bracts and bracteoles in three or four series, the inner bracts
