ing to pendent, 5 mm. long excluding peristome, 1 mm. in diameter, with a ring 
of darker-colored cells around the mouth, and constricted under the mouth when 
dry; collum 2 mm. long; outer peristome light-yellow, inner peristome as long, 
cilia 3 or 4. 
The leaf areolation of this plant suggests an affinity to Bryum ontariense, 
though the latter has not so distinct a margin of narrow, thick-walled, colored 
cells. It is distinguished from that species by the absence of radicles on the 
stem, which is dark-colored and beset with squamose rudimentary leaves, by the 
larger and looser leaf cells, the leaf margin not revolute, and the less crowded 
rosette of leaves at the apex of the stem.
