The Saprolegniinece constitute a group of the Phycomycetes 

 characterized by their possession of a well developed mycelium 

 of more or less richly branched siphonaceous filaments and by 

 the production of two kinds of reproductive bodies, viz. : (1) 

 small, non-sexual spores, generally appearing as warm spores, 

 and (2) sexual spores. 



The order has been divided into the following families : 

 A. Strictly aquatic fungi, with a mycelium of generally 

 stout siphonaceous filaments ; zoosporangia approximate- 

 ly cylindrical, not at all or little broader than the sup- 

 porting filaments : sexual fertilization doubtful : conidia 

 wanting. 



a. Vegetable filaments of uniform thick nes.s. 



1 . Saprotcg iiiareoi. 

 h.- Vegetable filaments constricted at intervals. 



2. Jje'ptoinitdcexe.
