WITH PLATE XXIx, 
The following notes are derived from observations made by 
the writer during the past season on certain aquatic fungi 
which have come under his notice, and, although other occu- 
pations have made it impossible to study some of the forms 
€numerated as thoroughly as their peculiarities merit, it is 
hoped that the notes and illustrations given may have a cer- 
tain interest from the fact that they deal with plants which 
are either wholly new or have been unobserved for twenty 
years or more since their original description. 
MONOBLEPHARIS Cornu. 
_Ina brief preliminary notice which appeared in the Bulle- 
tin de la Société Botanique,! Cornu first announced the dis- 
covery of a most remarkable and important genus of aquatic 
fungi which, on account of the fact that it was supposed to 
Produce zoospores having a single cilium, was named by him 
‘“‘Monoblepharis.” In the following year this writer’s well- 
known ‘‘Monographie des Saprolégniées? was published, in 
which he describes and figures two species of the genus, M. 
Sphaerica and M. polymorpha, referring incidentally to a third, 
- prolifera, which is neither described nor figured. The 
last name subsequently remained a momen nudum until the 
form was rediscovered and sufficiently described and figured 
by Reinsch, in an important paper published in 1878,* under
