[Vol. I. 



On leaves of Verhascum Thapsus, Catskill Mts., IsT. Y. (Peck) and 

 probably in other localities. 



22. Eamularia Mitell^, Pk. 33d Eep. K. Y. State Mus., p. 30. 

 Spots suborbicular, brown. Hyphse iiypophyllous, minutely tufted, 



short, nearly straight, slightly colored. Conidia straight, oblong or cylin- 

 drical, colorless, unequal in length, 8—20 x 3 



On living leaves of Mitella diphylla.^' N. Y. (Peck.) 



23. Ramularia NEM0PAi3"THis, C. & P. 29th Eep. N. Y. State Mus., 

 p. 52. 



Spots brovv'nish, darker above, indefinite. Hyphse hypoyhyllous, fas- 

 ciculate, short. Conidia fusiform or cylindrical, 20 x 4 



On leaves of Nemopantlies Canadensis, Y. (Clinton), New Hamp- 

 shire (Farlow). 



24. Eamularia brunnea, Pk., 30th Eep. ^N". Y. State Mus., p. 55. 

 Spots brown, unequal, suborbicular, sometimes confluent. Hyphse 



occupying the larger spots and giving them an ashy tint, epiphyllous, 

 short, delicate. Conidia cylindrical, colorless, very unequal in length, 

 12-40 X 3i fJ-. 



On living leaves of Tussilago Farfara, N. Y. (?) (Peck.) 

 We have seen no specimens. 



25. Eamularia Astragali, Ell. & Hoi. Jour. Mycol., I, p. 6. 

 Spots 2—4 mm., lead-colored below, brown above. Hyphse hypo- 



phyllous, fasciculate, continuous or faintly septate, nearly hyaline, but 

 with a faint yellowish tinge, undulate and subgeniculate, 80— 112 x 3—4 fJ-. 

 Conidia oblong-elliptical, uniseptate, hyaline, 15-22 x 7—9 !->■. 



On leaves of Astragalus Canadensis, Iowa (Holw^ay.) 



This, though allied to the preceding species is quite distinct on 

 account of its large, differently colored spots and broader conidia, which, 

 so far as we can see, are not concatenate. 



26. Eamularia Oxaltdis, Parlow. Appalachia, III, p. 251 (1884). 

 Amphigenous, forming small, circular, blackish spots, with a light- 

 colored center. Hyphse hyaline, very numerous, densely packed together, 

 55 — 75 X 3 — 4 /-^, the shorter ones simple, the longer ones vaguely branching. 

 Conidia hyaline, linear oblong, blunt pointed at both ends, 15—27 x 3 — 4 ^, 

 one celled but occasionally with an imperfect septum. 



On Oxalis acetosella, Kew Hampshire (Farlow.) 



27. Eamularia Act^e^, Ell. & Hoi. n. s. 



Amphigenous but mostly hypophyllous, appearing at first in patches 

 of irregular outline, limited partly by the veinlets of the leaf which 

 soon becomes yellowish in the affected parts, then dark brown or nearly 

 black, in irregular spots .2— .5 cm. across, with a sub-angular outline. 

 Hyphse fasciculate, continuous, hyaline, nearly straight, sparingly den- 

 ticulate above, 25—35 x 4—5 (exceptionaly 50—75 p- long). Conidia 

 oblong-cylindrical, nucleate and mostly 1-septate, 15—35 x 3i— 5M (mostly 

 25 X 5 <(J-).
