13. Peronospora Viciae (Berk.) DeBary, in Ann. Sci. Nat., Ser. 4, t. XX, p. 112. Botbytis 

 ViciAE Berk., in Journ. Hort. Soc, Lond., vol. I, p. 31, t. 4, fig. 23. [Syll-, vol. VII, 

 p. 245, No. 819.] 



Conidia and oospores on leaves of Leguminosae Papilionaceae, May and June. 



On Vicia Americana Mnhl., var. Linearis, Wats. 

 1565, (coll. by Mr. E. C. Coburn,) May 17, 1888, Zeandale, Riley county; M. A. 

 Carleton No. 109, oospores mature, June 4, 1888, Cloud county. 



14. Peronospora Arenariae(Berk.)Tul., in Compt. rend. Acad. des. Sci., t. XXXVIII (1854). 

 BoTBXTis Aeenakiae Berk., in Journ. Hort. Soc, Lond., vol. I, p. 31, t. 4, fig. 22; 

 in Ann. and Mag. Nat. Hist., Ser. 2, vol. VII. 



Var. macrospora Farlow, in Bot. Gaz., vol. IX, p. 38. 

 On leaves of Caryojjliylleai' November. Rare. 



On Silene antirrhina L. 



1130, on under sides of leaves of seedling plants, November 10, 1887, Manhattan. 



The identification of this specimen is somewhat doubtful, as no oospores could 

 be found. The conidiophores seemed quite different from those of P. alsinearum, 

 but I had no specimens of P. arenariae for comparison. 



15. Peronospora Lini Schroeter, in Bericht iiber die Thiitigk. der bot. Sect, der Schles. 

 Ges., J. 1865, S. 36.* Peeonospoea Lini E. & K., in Journal of Mycology, vol. Ill, 

 p. 126. 



On leaves and stems of Lineae, August. 



On Linum sulcatum Riddell. 



1077, August 20, 1887, Manhattan. 



Since no oospores have been found in the Kansas specimens, it is not certain 

 that P. Lini E. <fe K. is a synonym of Schroeter "s species. At any rate, the name 

 Peronospora Lini E. <fe K. cannot stand. The species seems to be very rare at Man- 

 hattan, specimens having been found but once. 



16. Peronospora Arlhuri Farlow, in Bot. Gaz., vol. VIII, p. 315. [Syll., vol. VII, p. 248,
