This moss is extremely variable, and is often confounded with the next 

 species, so much do the specimens differ in size, habit and colour, according to the 

 shade or moisture of the locality. The smooth or striate capsule, on which Spruce 

 laid so much weight, does not seem to be a matter of great importance, as the 

 striation appears to depend chiefly on the shrinking of the capsule-wall after 

 sporosis or drying.
