Plants small, in whitish to yellowish-green or dirty green mats or tufts, or 

 scattered among other bryophytes; stems to 3 cm or more long, with leaves, 

 0.65 mm broad, prostrate to ascending, pinnate or bipinnate, the lateral branches 

 frequent, short or becoming attenuate and very long flagelliform, ventral flagelli- 

 form branches not seen. Rhizoids from the scales of the tips of flagelliform 

 branches. Line of leaf insertion oblique, the leaves incubous. Stem leaves approxi- 

 mate to imbricate, spreading, plane or becoming concave in the outer part, quad- 

 rate to longer than broad, to 0.54 mm long, 0.8-1.0 mm wide at the base, the 

 dorsal base curved, the margins without teeth, quadrifid or often trifid to about 

 one-third of their length; segments subequal, incurved or spreading, long tri- 

 angular, from a 2- to 4-celled base, the apex acute and ending in one or two 

 cells; leaf cells at the base of the segments 30-36 p., quadrate-hexagonal, the walls 

 thin, with tiny trigones, the lumina rounded, the cuticle smooth. Underleaves a 

 little broader than the stem, concave, the segments erect, quadrifid to one-half 

 their length, the segments triangular, from a 2- to 3-celled base and ending in a 

 1- or 2-celled tip. Branch leaves and underleaves often somewhat smaller. Plants 

 monoicous. Male branches very short, the bracts in four to eight pairs, imbricate, 

 concave, bilobed to one-third of their length; antheridia solitary, large, short- 

 stalked. Female inflorescence on a short ventral branch, the bracts and bracteoles 

 in three or four series, light green, the bracts broadly ovate, 4- or 6-dentate. 

 Perianth whitish, cylindrical, fusiform, the mouth contracted, lobate and short- 

 ciliate, and denticulate. PI. 40. Fig. 5, a-c. 



Habitat: On soil, stumps, logs, trees, and over sandstone rocks at higher 

 elevations.
