This curious little moss differs from all others in the simple 

 structure of its capsule, which is very rudimentary in 

 comparison with those of all other genera. There is no 

 differentiation of the internal tissue into columella and 

 spore-forming cells. No columella is produced. The 

 spores are formed by the division into four of a limited 

 number (3 or 4) of spore mother- cells lying near the base. 

 These features have induced some bryologists to place 

 Archidium in an Order to itself. " The present is the 

 only European species, but there are several closely allied 

 species in N. America" (Dixon).
