Dicranella Apolensis sp. nov. 
Dioicous. Slender stems up to 2.5 cm. high, with few 
branches: leaves lanceolate, falcate-secund, keeled, some- 
what revolute at margin, mostly acutely pointed, entire ex- 
cept at apex, which often terminates in 2 or 3 teeth of about 
equal length; costa vanishing just below apex, well defined 
below and scarcely one fourth the width of the leaf-base; 
stem-leaves 1.5 mm. long, perichaetial leaves very similar 
but a little longer (2 mm.) and more slender-pointed ; leaf- 
cells quite uniform throughout leaf, mostly rectangular, from 
slightly elongated to two and one half times longer than 
broad: seta 4 mm. long; capsule erect, ovate, small-mouthed 
and smooth, 0.75 mm. long, the lid with obliquely rostrate 
beak about the same length; exothecal cells mostly one and 
one half to two times longer than broad with thick not 
sinuous walls; annulus large; teeth pale and irregular, 
papillose, often split nearly to base or cribrose, with points 
free or united: spores rough, up to 18 » in diameter. 
On sand along stream, Apolo, July 1, 1902 (1743). 
DicRANELLA KunzEAna (C. Miil:) Mitt. 
Consata, 900 meters, June 13, 1902 (1740); Tumupasa, 
5400 meters, January 25, 1902 (1736). Determined from 
description only. 
Dicranella subserrulata sp. nov. 
Apparently dioicous. Stems 2 mm. high: leaves spread- 
ing, flexuous, the upper 2.5 mm. long, narrowly elongated- 
lanceolate, keeled, acute and rather sharply dentate at apex, 
margin nearly flat and distinctly serrulate about one third down ; 
leaf-lamina pale brown, distinct to apex, larger cells of upper 
leaf about 5 x 15, of lower leaf 12 x 503; costa nearly 
percurrent, very distinct to base, 50-60” wide below and 
about one fourth the width of the leaf-base: seta up to 8 mm. 
high; capsule oblong, nearly erect, smooth and wide- 
mouthed when dry and empty, with conical, obliquely 
beaked lid often exceeding it in length; teeth of peristome 
regular, divided three fourths down with slender, red, papillose 
segments; annulus large: spores, slightly rough, up to 16 #in 
diameter. 
On sandy cut-bank, Huainachoirisa river, July 28, 1902 
(1741). The two preceding species clearly belong to the 
subgenus J/icrodus, while this has the peristome rather of a 
true Dicranella.
