Fronds small, black, opaque, glanduliterous. Capsule with the 
long and slender valves much twisted in drying, and bearing numer- 
ous stomata in its walls.

fo». This species is also evidently a connecting link between ¢hts and 
the foHtowing-gents. It is well marked by the pale color of 
the frond, by the large (immature) spores and by the minute 
subprismatic angular granulose elaters. ? 
Columella with long jagged squarrose filaments attached to its 
surface, among which the elaters and spores are entangled. Cells 
of the frond smaller than in A. punctatus, the frond being more 
closely areolated. Inyolucre of a lax hyaline texture, (punc- 
tate like the frond); the cells at its base oblong, near the apex 
rhombic, at the mouth somewhat transversely elongated.
