generation consists of a tissue called a gonimoblast which produces 

 carpospores in a number of ways, often within a special enveloping 

 structure called the cystocarp (See Figs. 38-39). The Hberation of the 

 carpospores and their germination begins the development of the sporo- 

 phyte generation again . whereby the cycle is repeated. 



The genus Gracilaria may be used as an example of this kind of 

 life cycle (Fig. 12) which is characteristic of most of the red algae ex- 

 cept those of the orders Bangiales and Nemalionales,
