Preliminarij List of Wisconsin Parasitic Fungi. 127 



The teleutospores are often forked; in sonae cases the divisioa ex- 

 tends merely through the terminal papilla; in others the lower cell is pro- 

 duced into a thickened papilla just below the septum. 



170. Puccini A tomipaka, n. sp. 



Uredo and teleutospores on a spec'es of Bromus, apparently B, cili- 

 atus L. La Crosse, Pammel. 



II. Sori small, round, or little elongated, on the uppsr surface of the 

 leaf. Spores commonly round, somewhat roughened with blunt, 

 inconspicuous warts; pale yellow, 22-26 /.i. 



III, S ri compact, black, long covered by the epidermis; round or 

 slightly elongated, usually about .2 mm. in diameter. Spores pale 

 chestnut-brown, thin walled, without apical thickening; irregu- 

 larly oblong, sessile; 2-5-celled, often tomipa,rous; 13-23x35-43 /<. 



The species is remarkable from the fact that the spores are commonly 

 3-4-celled, with the uppermost septum oblique or not infrequently jjar- 

 allel to the axis of the spore, which is thus made to consist of more than 

 one row of cells. It somewhat resembles P. triarticulata B. & C, which 

 occurs on Ehjmus, and which has 3-celled spores; but these are longer and 

 differently shaped. 



171. PucciNiA BARYl (B. & Br.) (P. stHatula Thuem., P. linearis Pk.). 



Uredo and teleutospores on some dead grass, possibly Andropo- 

 gon scoparius Michx. Madison, 

 Well marked by the strongly clubbed paraphyses. 



172. PucciNiA ANDROPOGI Schw. (P. elUsiana Thuem.). 



Teleutospores on Andropogon scopariv.s Mx. Madison; Milwaukee, 

 Lapham; La Crosse, Pammel, 

 This has been compare 1 with Schweinitzian specimens, by Dr, Farlow. 

 The teleutospores are not unlike those of P. cesati Schr., as described by 

 Winter. 



173. PucciNiA ARUNDINARIAE Schw. 



Teleutospores on dead leaves of Spartina cynosuroides Willd., in 

 winter and spring. Madison . 



174. PucciNiA EMACULATA Schw. (P. graminls P., var. hrevicarpa Peck). 



Teleutospores on Panicum capillare L. Madison; La Crosse, Pammel. 



175. PucciNiA YEXANS Farlow. 



The form described by Peck as Uromyces brandegeei, but now held to be 

 the uredo or mesosporic form of this species, was found once on Bouteloua 

 racemosa Lag., at La Crosse, by Mr. Pammel, The quantity examined was 

 small, and no teleutospores were seen.
