Preliminary List of Wisconsin Parasitic Fungi. 139' 



251. USTILAGO SPEEMOPHORUS B. & C. 



In ovaries of Evagrostis poaeoides Beauv., var. megastacliya Gray. 

 Madison; Sauk City, Liiders. 

 The affected ovaries arc round or ellipsoidal, scarcely enlarged, and 

 remain long unbroken, enclosed by the paleae. Spores thin-walled, brown, 

 round or slightly elongated, finely echinulate, 6x8, 8x8 — 10x8/<. 



The appearance of the ovaries recalls Tilletia decipiens (Pers.) as repre- 

 sented in Scandinavian specimens as Agrostis, from Professor Blytt, but 

 the spores of that species measure 23 — 28 /^ 



252. UsTiLAGO JUNCi Schw. 



Pedicels and perianth of Juncics tenuis Willd. (?) in June.. 

 Stoughton. 

 Apparently referrible to Cornu's genus Cintractia. 



253. USTILAGO SYNTHERISMAE ScllW. 



Inflorescence of Cenchrus tribuloides L. La Ci'osse, Pammel. 



254. Tilletia foetens (B. & C.) (T. laevis Kuehn). 



In ovaries of Triticum vidgare Vill. La Crosse, Pammel. 

 The "bunt" or hard smut of wheat, published in 1860 as Ustilago foetens 

 B, & C, in Ravenel's Fungi Carol. Exsicc, V., 100. 



255. Tilletia striaepormis (West) ? {Ustilago salveii B. & Br!). 



In leaves of Phleiim pratense L. and Elymus canadensis L.,var. glau- 

 cifolius. Stoughton, Madison; La Crosse, Pammel. 

 Referred here on the authority of Winter. 



256. Entyloma compositarum Farlow. {Protomyces polysporus Peck). 



In leaves of Silphium integrifolium Mx., Ambrosia artemisiaefolia 

 L., A. psilostachya D C. and Lepacliys pinnata Torr. & Gr. Mad- 

 ison, Ithaca; LaCrosse, Pammel. 

 Occiu's also on Aster puniceus L., in the East, and has been described on 

 Ambrosia trifida L., by Peck (34th Repcrt, pp. 45-6). 



257. Entyloma lobeliae Farlow. 



In leaves of Lobelia inflata L. Delton, Pammel. 



258. Entyloma crastophilum Sacc. (?) 



In sheaths of Zizania aquatica L. Madison. 

 This agrees well with the description in all respects save the thickening 

 of the angles of the spores, which I have not noticed. I have not been 

 able to compare it with authentic specimens. 



259. Entyloma linariae Schroeter. 



In leaves of Veronica peregina L. Madison. 

 This occurs in round, thickened portions of the leaf, similar to those on 

 Linaria, in which it is found in Europe.
