Parasitic Fungi of Illimois. 227 
4a. grossularie, DC. 
Hypogenous. Spots distinct, swollen, yellow; ecidia 
densely clustered, medium size, edge entire and erect or often 
many times split and recurved; spores subglobose, epispore very 
thin, obscurely roughened. 
On leaves and fruit of Ribes rotundifolium: McLean, May 
22, 4730, May 23, 4758, May 29, 4814, May 30, 4836. Cudzi- 
vated gooseberry: McLean, May 31, 4847, coll. C. A. Hart; 
Champaign, coll. T. J. Burrill. 
4K. epilobii, DC. 
Amphigenous. Aicidia scattered rather uniformly over 
the surfaces of the leaves, sometimes more abundant beneath, 
short, rather coarsely and deeply split and much recurved; 
spores subglobose, epispore thin, smooth or nearly so, 15-18 4; 
spermagonia honey-yellow, appearing before the ecidia, scat- 
tered over both surfaces, more numerous above. 
On Enothera biennis: Union, April 29, 5019. 
There is much reason to suppose that this is Uromyces 
aenothere, Burrill. The specimens on Ginothera linifolia, from 
Jackson county, are, if not identical, exceedingly similar, as 
may be learned by comparing the descriptions. Moreover, Mr. 
C. A. Hart collected May 27th, 1883, in McLean county, on 
the radical leaves of what is supposed to be @'nothera biennis, 
a Uredo, which is undistinguishable from the uredo form of 
this Uromyces. The sori of Mr. Hart’s specimens are developed 
on both surfaces of the leaves, but the greater number open on 
the under side —the only point of difference noted. 
4. cenothere, Peck. 
Hypophyllous, or very sparingly produced above. Spots 
conspicuous, usually purple, scarcely thickened; ecidia crowded 
in a somewhat definite circle, with a small central vacant area, 
short, deeply and rather coarsely split and much recurved; 
spores subglobose, epispore thin, very minutely tuberculate, 
15-18 »; spermagonia few, very inconspicuous, on the upper 
side of the leaf in the center of the spots, honey-yellow.
