58 SEMI-CENTENNIAL OF TORREY BOTANICAL CLUB 
were entirely negative until some of the common species of water 
bacteria were introduced into one of the cultures which had been 
growing well but producing only a profusion of zoosporangia. 
After the bacteria had been growing in the culture but a few days 
the material was examined and a plentiful supply of oogonia and 
antheridia was found to have been formed. Bacteria were then 
introduced into other pure cultures with a like result. Pure 
cultures for zoosporic material and cultures contaminated with 
bacteria for the sex-organs were then grown on small bits of meat 
and fly larvae which had been sterilized and hardened in alcohol 
with the result that extremely орда material was had for 
laboratory demonstration. 
This species was originally described from material collected 
in Germany.
