almost all open places. They are so large that with 

 a hand-glass many of the principal parts may be made 

 out and will thus serve as a foundation for a study of 

 other mosses. 



FRUITING PORTION (SPOROPHYTE). 



The most striking part of the plant (Gametophyte) is 

 the fruiting portion (sporophyte) with its parts. The 

 spore-case is a thin-walled cylindrical box with 

 four or six sharp edges running lengthwise. The 

 spore-case is borne on a 

 flexible pedicel (seta), the
