BY J, B. ELLIS AXD W. A, KELLERMAN. 



Pekonospora Oxybaphi, E. & K.— On O. nyctagineus. Manhattan, 

 Ks., June, 1884. Conidiophores simple below, about 3 times dichoto- 

 mously branched above, the ultimate divisions stout and slightly cm'ved ; 

 conidia elliptical, pale violet-brown, 20 — 26x12— 15/^-. Oospores 35 — 40/^-, 

 rusty brown, epispore rough. 



PucciNiA LiTHOSPERMi, E. & K.— On Lithospermum canescens^ 

 Manhattan. Ks. ^cidium and uredo not seen. Teletuospores— sori 

 amphigenous, round, black, soon naked, scattered, small, (imm.) spores 

 elongated, mostly attenuated above, strongly constricted, of a deep red- 

 dish brown above, paler below, 32 — 45 x 20 — 23/^, epispore smooth, 

 thickened above so as to form an obtuse point which is often oblique but 

 sometimes the apex is regularly rounded, pedicels rather stout, as long as 

 or longer than the spore. 



Cercospora condejjsata, E. & K.— On leaves of Gleditschia tria- 

 cantlios. Manhattan, Ks., July, '84. On small (1 — 2 mm.) brown or dirty 

 white round spots with an obscure dark border. Hyphse mostly epiphyl- 

 lous, brown, (continuous)? obtuse, subdenticulate above, 30 — 80 x 4 — 5/^, 

 densely compacted so as to form little black tubercles much resembling 

 perithecia; conidia slender or concave-cylindrical, nucleate and pale 

 brown, becoming 6—9 septate, 60—75 x 4 /^-.— var. Desmantlvi (on D. 

 brachylohus, Great Bend, Ks.) differs in its shorter hyphae and shorter 

 (30—35 P-) 1-septate conidia and in the absence of any very definite spots, 

 differences which are probably due to immaturity. 



Cercospora Fraxint, E. & K. — On living leaves of Fraxinus, Man- 

 liattan, Ks., Sept. '84. Scattered over the lower surface of the leaf on 

 small, rusty brown spots, limited by the veinlets of the leaf and forming 

 at length, by confluence, much larger (^ — 1 cm.) patches with an irregular 

 outline. The leaf is also mottled above with rusty brown in which 

 small, light colored spots mark the position of the denser tufts beneath. 

 Hyphae densely tufted, nearly hyaline, short, (16—25 /-'-) lax, slightly 

 swollen at the base, bearing the cylindrical, nearly hyaline {vdth a slight 

 yellowish tinge) 3 — 4 septate, granular and nucleate conidia 70,-100 x 5—6/^- 

 more or less curved and ends obtuse. Accompanied by an immature 

 Splmrella of which it is probably the conidial stage. This species varies 

 considerably from the usual type of Corcospora standing rather equivo- 

 cally between this genus and Bamularie. 



Cercospora Dianther^e, E. & K. — On Dianthem Amencana. 

 Topeka, Ks., (Popenoe.) Sept. 1884. On round white spots, 2 — 4 mm. in 



* Collected by W. A. Kellerman during the season of 1884.
