On comparison of specimens of this superb moss with the 
Bryum roseum of Europe, it would certainly, at first sight, 
seem to be distinct, although considered identical in Drum- 
mond's Musc. Amer:- Its habit is very much like that of 
Bryum umbraculum, Hooker, Musc. Exot. tab. 133. It is 
a profuse fruit-bearer, producing frequently five peduncles 
from the same stem, exceeding in size the European co- 
species, and remarkable for its beauty. In shade of pine 
Woods, on decaying logs and stumps of trees. Chelmsford! 
Also Tewksbury, B. D. Greene! Y also possess specimens 
without fruit, which I gathered at Lancaster, N. H., near the 
White Mountains.
