92 PHYCOMYCETEAE 



Key to the Family and Genera of Order Monoblepharidales 



Single family. Family Monoblepharidaceae 



Branching mycelium constricted into cylindrical or rounded coenocytic seg- 

 ments, terminal ones becoming zoosporangia. Sexual reproduction not 

 certainly demonstrated. Gonapodya 



Mycelium often not extensively branched, not constricted. Zoosporangia ter- 

 minal. Antherids and oogones terminal or subterminal. Egg cells not 

 flagellate. 

 Egg cells not motile by means of the flagellum of the sperm. 



Monoblepharis 

 Egg cells motile by means of the flagellum of the fertilizing sperm. 



Monoblepharella
