SOME MILDEWS OF ILLINOIS. 
BY L. H. PAMAJEL, ST. LOUIS, MO. 
For the past two seasons I have had an opportunity of collecting at 
several points in Illinois, near Chicago at Palatine, Cheltenham, Argyle 
Park and Lake View; also in the bottoms opposite St. Louis, which is a 
rich field for the collector not only in phsenogams but fungi. 
In the species enumerated, I have adopted the synonomv of the 
excellent paper on “The Erysiphese of Illinois” by Prof. T. J. Burrill 
and Mr. F. S. Earle. From this paper it seems that some species are 
somewhat local, so that it will be of interest to add new localities for 
those and also such additional hosts as they were found on. One species 
new to the state has also been added.
