10. Calypogeia boliviana Fulford, sp. nov. 



Caules foliosi ad 3 cm longos, olivacei; folia late triangularia, longe decurrentia, 

 apice obtuso rotundato; foliorum cellulae superiores 26-40 X 20-26 ft, parietibus 

 tenuibus; amphigastria late ovata, apice rotundato vel retuso, cellulis longis; in- 

 florescentiae non visae. 



Plants of medium size, olive-green, in thin mats or scattered among other 

 bryophytes; stems to 3 cm or more long, with leaves, to 2 mm wide, occasionally 

 branched; branches leafy, long, ventral-intercalary in the axils of the underleaves. 

 Rhizoids occasional, short, in light yellowish tufts from near the bases of the under- 

 leaves. Leaf insertion slightly oblique, nearly longitudinal. Leaves distant to approxi- 

 mate, inconspicuously bordered by a row of smaller cells, spreading, asymmetric, 

 broadly triangular, 0.75 mm long, 0.84 mm wide below, the dorsal base curved to 

 cordate, the ventral base very long-decurrent, the apex narrow, blunt-rounded; cells 

 of the border 19-26 X 15-26 /x, thin-walled; cells of the upper part of the leaf 

 26-40 X 20-26 jx, the walls thin, without trigones, the cuticle punctate. Underleaves 

 ovate, to 0.6 mm long, below twice as broad as the stem, narrowed to the blunt- 

 rounded or retuse apex, the margins entire, the cells long, thin-walled. Male and 

 female inflorescences and sporophyte not seen.

Plants of medium to large size, olive-green to yellowish, in depressed mats; stems 

 to 6 cm long, with leaves, to 2 mm wide, sparingly to abundantly irregularly pin- 

 nate; branches, ventral-intercalary leafy or short sexual. Rhizoids abundant, long, 

 branched at the tips, in light brown tufts from small cells near the bases of under- 

 leaves. Leaf insertion slightly oblique, nearly longitudinal. Leaves imbricate, widely 

 spreading to patent, more or less bordered by smaller cells, orbicular to rectangular, 

 0.95-1.7 mm long, 0.66 mm wide at the middle, the apex broad, truncate-rounded, 

 the dorsal base slightly curved, the ventral base decurrent, the margin crenulate;
