 not yet determined, occurring in large patches over many acres of 

 damp ground in the Werribee district. Mr. A. D. Hardy, F.L.S., 

 called attention to the exhibit, and ventured the opinion that it 

 was probably a species of Vaucheria, but it would require micro- 

 scopical examination, and then only if in fruiting condition, to 

 determine the precise species.
