In size and general aspect M. verrucosa is similar to M. capillaris and the 

 distribution patterns of the two overlap, but in M. capillaris the cuticle of the 

 leaves and underleaves is faintly to conspicuously verruculose rather than plainly 

 papillose. The coarsely papillose cuticle of the cells immediately distinguishes 

 M. verrucosa from the other species of Microlepidozia. 



3. Microlepidozia herzogiana (Stephani) Fulford, Brittonia 14: 122. 1962. 

 Lepidozia herzogiana Stephani, Bibliot. Bot. 21(87): 226. /. 168, c. 1916. 



Plants filiform, deeply pigmented with yellow-brown, in mats or among 

 other bryophytes; stems slender, prostrate, to 5 mm long, with leaves to 0.35 mm 

 broad, regularly pinnate to bipinnate; lateral branches 1-2 mm apart, 2 mm long, 

 diverging at a wide angle, ventral branches occasional, flagelliform, with scale- 

 like leaves. Line of leaf insertion transverse. Stem leaves distant to subimbricate, 

 spreading but curved upward in the outer part, subquadrate, to 0.2 mm long 

 and broad, quadrifid to three-fourths their length, with a lamina one or two rows 

 of cells high and eight cells wide, the segments subulate, four to seven cells long, 

 two (three) cells wide below, ending in a uniseriate tip of two or three cells, the 

 cells 24-27x18 fi, the tip cell 30-34x16 p., the walls slightly thickened, the 

 cuticle striolate-verruculose. Underleaves trifid or bifid, the segments of unequal 

 length, the cells as in the leaf. Plant dioicous, monoicous (?). Female in- 

 florescence on a short ventral sexual branch, the bracts and bracteoles in three or 

 four series, the inner series laciniate-ciliate above. Perianth long (old), the 

 mouth short-ciliate. Male inflorescence and sporophyte not seen. PI. 50.

Plants filiform, light yellow-brown; stems very slender, 3-4 cm long, with 

 leaves to 0.3-0.4 mm broad, regularly bipinnately branched, the lateral branches 

 3 mm apart, to 4 mm long, diverging at a wide angle, the ventral branches 

 flagelliform; stem in transverse section six to eight cells across, the cortical 

 layer of about 12 cells slightly larger than the cells of the medulla. Line of 

 leaf insertion transverse. Stem leaves distant to approximate, spreading or
