The peristome in this moss is very thin and fragile and is thus probably 

 destroyed by adhesion to the lid, for its presence is extremely rare. The 

 dull paper-like calyptras are the first objects to direct attention to this 

 species, which is more or less generally distributed, but never occurs in great 

 quantity.
