23. Mnium (Roellia) simplez Kindb. Bryum simplex 
Kindb. cat. Canad. m. 
Nearly allied to M. lucidum (Britton) Brotherus in Hed-

cilia, the small spores and the narrow leaf-cells, etc. — 
Differs from it: Leaves smaller, crowded and not decurrent, 
the comal ones shorter and oval-spathulate, those of the 
shoots nearly similar, more numerous and not distant, not 
or indistinctly limbate ; capsule constricted below the wide 
mouth; lid obtuse and mamillate.
