bearing antheridial patcnes. Cystocarps are minute and p^lobularv 

 beinor lodored among monilifonn nlaments of the cortical layer. • 



Development of cystocarps : Carpoo-onial branch is produced 

 as a lateral branch from a lower articulation of peripheral filaments 

 and is composed of a curved row of 5 cells, of which the cell beneath 

 the hypogenal one is the larp-est and the next two cells remain 

 as pedicel for the procarp, each of which laterally carries sterile 

 branches. After fertilization, an ooblastema filament is set forth, 

 from the carpop-onium or probably from fused cell of carpoponium and 

 hypooenal ceils, (this process, however, is unknown to me at 

 present.) One of the lower articulations of the peripheral 

 filaments acts as an auxiliary cell and mostly two auxiliary cells 

 standim ァ near to each other are acted upon by an ooblastema 

 filament. By this way the fusion of two auxiliary cells and the 

 ooblastema filament takes place and the latter is still protruded: 

 as to 'JO further. From the fused rep"ioii of the ooblastema filament 

 carpospores are produced, which by repeated division form a simple 

 minute globular nucleus of a cystocarp. 



Color red. Substance very gelatinous and the plant firmly 

 adheres to paper in drying 



Hab. On rocks and stones between tide marks. Cape Nomo,. 

 Futaye (Isl. Amakusa). Cystocarps : spring.
