"Hyphae rather stout or slender. Sporangia formed from tips of the 

 hyphae, oval, pyriform, ventricose-clavate, elongate-pyriform to clavate 

 or cylindric-clavate, the later ones arising either by cymose or pseudo- 

 cymose arrangement, as in Achlya, or by internal proliferation as in 

 Saprolegnia, both modes occurring earlier or later in the development 

 of one and the same species, or frequently on the same main hypha. 

 Spores diplanetic, their form and behavior as in Saprolegnia. Gemmae 

 present. Oogonia terminal or torulose, occasionally intercalary; eggs
