Thompson. 
On Rosa setigera, Rooks county, Feb. 17, 1893. 
This species, which is quite common in many parts of the state, usually 
attacks shoots of the present year’s growth, killing outright many in 
the same related group. Even the novice may readily identify it, as it 
commonly covers the lower part of the stems with a soft, black tomen- 
tum, resembling somewhat the black knot on plum twigs. 
. Phragmidium subcorticium, (Schrank) Wint. I, IT, III. 
193):

On Rosa setigera, Riley county, Sept. 7, 1892, Carleton.

This species is also widely distributed, and is more or less common every 
year in all three stages, which are readily separated in their gross forms 
without the aid of the microscope. A fine species, with well-marked 
characteristics, but usually not destructive with us.
