14. Peronosporae Arenariae (Berk.) Tul. var. macrospora Fad. 



On Silene antirrhina L. 



1975, with abundant mature OOSPORES, on leaves, APRIL 21, 1890, Manhattan; 

 1938, with abundant mature oospores, April 27, 1890, Manhattan. 



Both of these numbers were collected on seedling plants growing in a wheat tield. 

 The presence of oospores in these specimens now renders certain their identity with 

 the variety macrospora of Farlow, since the oospores agree exactly with the descrip- 

 tion given by him in "Additions to the Peronosporeae of the United States," in 

 Botanical Gazette, Vol. IX, No. 3, March, 1881, p. 38, No. 12*. In all the specimens 

 both oospores and conidia were abundant.

 On Oaliuni Aparene L. 

 1939, with mature oospores, on leaves, April 27, 1890, Pottawatomie county, 

 northwest of St. George. 



This species found this spring for the first time within the State, was abundant 

 on some seedling Galium growing along an old feace. The oospores were found in 

 the oldest leaves attacked, and agreed very closely with the description and figures 

 given by de Bary.
