diverging at a wide angle; flagelliform branches frequent. Leaves imbricate, 

 spreading, becoming somewhat deflexed on drying, asymmetrically long-ovate, 

 to 1.4 mm long, 0.55 mm broad at the base, narrowing a little to the transversely 

 truncate, serrulate to spinose, obscurely tridentate apex; teeth very short, acute, 

 broad, the sinuses lunulate, the margins serrulate to spinose; leaf-cells sub- 

 quadrate to rectangular in outline, the lumina rounded, the walls of the cells of 

 the apical portion and the margins uniformly thickened, those of the interior 

 thin with small but distinct trigones, the cuticle verruculose; cells of the apical 

 portion 18 X 18 fi. Underleaves imbricate, connate by several cells with one leaf, 

 in part hyaline, quadrate, mostly 0.48 X 0.48 mm, the lateral margins entire, 

 serrate, or dentate, the apex 3-6-toothed, the teeth two to five cells broad at the 

 base, two to four cells high, mostly serrate to dentate, the cells of the marginal 

 rows (mostly of the teeth) hyaline, verruculose, with uniformly thin walls, those 

 of the interior chlorophyllose, with thicker walls and small trigones. Sexual 

 branches and sporophyte not seen. Fig. 34, a-d.

Plants of medium size, light green to olive-green, becoming a little pigmented 

 with brown ; stems slender, to 5 cm long, with leaves to 3 cm broad, prostrate ; 

 lateral branches mostly 5 mm apart, diverging at a wide angle; flagelliform 

 branches numerous, long. Leaves imbricate, spreading, plane or nearly so, some- 

 times a little deflexed on drying, asymmetric, long-ovate, mostly 1.4 mm long, 

 0.65 mm wide at the base, narrowing a little to the transversely truncate, tri- 

 dentate apex ; teeth mostly one to three cells long and two to four cells broad, 

 the sinuses lunulate, the margins entire to serrulate ; leaf -cells quadrate to 

 rectangular in outline, thin-walled, the trigones small but distinct, the lumina 

 rounded, the cuticle verruculose ; cells of the apical region averaging 25 X 25 fi. 

 Underleaves imbricate, squarrose in the upper part, connate by a few cells with 

 one leaf, subquadrate, in part hyaline, 0.48-0.56 mm long, 0.56-0.64 mm broad, 

 the apex with three to six, serrate to spinose-dentate teeth or lobes, the teeth to 

 four cells broad, two to four cells high, the lateral margins serrate or with one 

 or more teeth, the cells of the marginal one to four rows (mostly of the teeth) 

 hyaline, strongly verruculose, with uniformly thickened walls without trigones, 

 the cells of the interior chlorophyllose, with conspicuous trigones and unequally 

 thickened walls. Sexual branches and sporophytes not seen. Fig. 35, a-d. 



Habitat : In depressed mats on logs and bases of trees in woods.
