seen them enter. After impregnation I believe the opening closes, 

 though this point is not absolute, and the spore matures, changing 

 from its dark green to a dark reddish-brown. 



The species whose life history I have studied, is nearly allied to 

 Q<1. Hothii of Europe, but is I believe distinct and undescribed. I 

 would offer for it the name (Edogonium Huntii, after Dr. J. G. Hunt, 

 to whose aid and direction, whatever success may attend any micro-

 description. 



(Edogonium Huntii. Gynandrous. Male plant slightly curved, 

 attached by a small foot, generally, to the cell which has been emptied

 very dark green in cells which are crowded with granular protoplasm.
