 Calypogeia puiggarii Stephani, Spec. Hep. 3: 405. 1908. 



Plants of medium size, in dense light green to yellowish mats on damp soil or 

 with other bryophytes; stems rigid, compact, to 1.5 cm long, with leaves to 2 mm 

 broad, irregularly pinnate; branches infrequent, leafy, short or long, ventral-inter- 

 calary from the axils of the underleaves; stem in transverse section of similar cells 

 throughout. Rhizoids abundant, in large, light tan tufts from the bases of 

 underleaves. Line of leaf insertion oblique. Leaves densely imbricate, erect spread- 

 ing, ovate, 0.6-1.0 mm long, 0.4-0.6 mm wide at the middle, narrowing to the shortly 

 bifid or occasionally blunt-acute apex, the dorsal base curved or semi-cordate, the 

 ventral base scarcely decurrent; cells of the upper part of the leaf rounded, 26-40 X 

 26-35 fi, the walls thickened, the trigones small, conspicuous, with concave sides, 

 the cuticle faintly verruculose. Underleaves imbricate, 3 or 4 times as broad as 

 the stem, tending to be transversely elliptical, deeply set on the stem, bifid to 

 one-half, the segments broadly triangular, sometimes with the suggestion of a broad 

 tooth on the outer wall, the sinus broad, U- or V-shaped. Male and female inflores- 

 cences and sporophyte not seen.

18: 75. /. 23. 1962. 



Calypogeia peruviana var. subintegra Gottsche, Lindenberg & Nees, Syn. Hep. 712. 1847. 



Plants of medium size, light green to yellow-green becoming yellow-brown, in 

 mats or among other bryophytes; stems creeping, rarely stout, to 5 cm long, with 

 leaves to 2 mm broad, frequently branched; branches leafy or small-leaved or 

 flagelliform, or short-sexual, ventral-intercalary from the axils of the underleaves; 

 stem in transverse section of thin-walled cells, the cells of the cortical layer smaller 

 than those of the medulla except in the area of leaf-attachment. Rhizoids numerous, 

 hyaline, in tufts from the bases of underleaves. Line of leaf insertion curved in 

 the upper part. Leaves imbricate, broadly ovate to oblong, 0.6-1.6 mm long, 0.4- 



I. 6 mm wide below, plane, the dorsal base curved, the ventral base not decurrent, 

 the apex broad or narrowed, entire or an occasional leaf shortly bidentate, the 

 teeth short; cells mostly hexagonal, in the upper part of the leaf 30-40 X 25-35 fi, 

 thin-walled, without trigones, the cuticle essentially smooth. Underleaves bifid to 

 one-half their length, broadly truncate-ovate to orbicular in outline, the segments 

 broad-triangular, only rarely with a blunt tooth on the outer margin, the base
