may be connected with each other, each cell liberates its 

 contained antherozoids into the surrounding medium 

 through its own proper mouth. 



The antheridium usually consists of a flask-shaped cell 

 with a more or less elongated neck, which at maturity 

 becomes perforated at the apex for the discharge of the 

 antherozoids. 



Laboulbenieae 



In this family the antherozoids are also produced endo- 

 genously in more or less flask-shaped antheridial cells ; 

 these cells are often six in number, closely compacted 

 together, but instead of being wholly or partly free from 

 each other, both the necks and venters are closely united 

 below, and empty their contents into a common cavity 

 furnished with a neck through which the antherozoids 

 escape. 



Zodiomyceteae 



In this family, including only two known genera, the 

 antherozoids are produced exogenously. As a rule, the 

 antheridial branches are not highly differentiated, the rod- 

 shaped antherozoids being produced at the tips of 

 branchlets, from which they become separated and adhere 

 to the trichogyne. 



The position of this family is not certain ; the presence 

 of asci locate it technically in the Ascomycetes.
