This moss comes near in general appearance to some of the 
small varieties of Dicranum scoparium, and perhaps still more 
to D. Scottianum, It is remarkable, however, in having a downy 
substance on the whole length of the stalk, leaves of a much 
softer nature than the species just mentioned, narrower, and very 
strongly serrated, curved when moist, only slightly flexuose when 
dry, and then exceedingly brittle.
