a sporophyte (Fig. 596, .5, t, c), which is the Capsule. These ripened 

 spores, in turn, germinate to produce a new gametophyte which, in its 

 embryonic state, is called the Protonema. It will be observed that the

 A, showing section through complete spore- 

 bearing body — the apothecium ; h, the hyme-

 enlarged section of a portion of above showing 

 a, b, c, d, e,f, asci, in various sizes and in various 

 stages of spore development taking place within 

 them, spores are mature in /, sh, the false paren- 

 chyma made up of intertwining hyphae.

 found lid or operculum; /, the capsule; s, the 

 leafless stem, of sporophyte or pedicel. (Fraak.) 



relative positions of sporophyte and gametophyte are exactly the 

 reverse of what they are in the flowering plant. 



Although the hair-cap moss is somewhat used in medicine, yet
