in the "Phycotheca Bor.-Am.", No. 386, a tetrasporic specimen 

 from Key West is found. The tetraspores are scattered over the 

 whole surface of the thallus in the cortical layer and are cruci- 

 ately divided. 



Of a female plant a fragment only was gathered. The cystocarps 

 are scattered over the surface 

 of the thallus ; they are hemi- 

 spherical prominent and pro- 

 vided with an apical porus. 

 Fig. 383 shows a longitudinal 

 section through the middle 

 of a nearly ripened cysto- 

 carp ; in the middle the pla- 

 cental branch is seen from 

 which the gonimoblasts are 

 formed. Seen from above the 



cystocarps form spherical
