yellow, about 75 diam.; conidia oblong, 12-23X 3-3 Mu, slightly 
curved and obtusely pointed at the ends, continuous. 
This can hardly be Cylindrosporim Senecionis B. and Br. Ann. 
Nat. Hist. no. 1613; Grev. 5: 58, which “forms white con- 
spicuous patches,” with flexuous flocci and cylindrical spores and 
belongs apparently among the Mucedineae. 
On the California specimens are also small superficial per- 
forated perithecia, on a mycelium like that of the Erysipheae.

CYLINDROSPORIUM KeELLoGGI E. & E. 
On living leaves of Quercus Kelloggui Amador Co., Calif. 
(Hansen, no. 1357.) 
Spots numerous, small (1-2 mm.) very dark brown at first, 
more or less whitening out in the center with a dark narrow mar- 
gin, often confluent, forming irregularly shaped light brown dead 
areas 1%4-I cm. or more in extent; acervuli hypophyllous, 110- 
150» diam., erumpent in flesh-colored conglutinated heaps be- 
coming nearly black; conidia cylindrical, more or less bent, 
nucleate, becoming about 3-septate, 40-65 X2%4-3p. 
CYLINDROSPORIUM LupPINI E. & E. 
On leaves of Lupinus cytisoides and L. latifolius, Yosemite, 
Calif., June, 1895. (Davis, no. 9514.) 
Spots irregular, suborbicular, 2-4 mm. or often extending along 
the side of the leaf or occupying the upper part of the leaf, dull 
reddish brown; acervuli amphigenous, pale, about 75. diam.; 
conidia fusoid-filiform or spiculiform, nucleate, straight, contin- 
uous, I5-23X1 4-1 lp. 
Differs from C. Jongispora Ell. & Dearness, in its larger spores 
and much shorter continuous conidia. ¢ 
MarsoniA BAPTISIAE E. & E. 
On leaves ot Baptisia leucantha, Ames, Iowa, Oct., 1895. 
(Coll. Geo. W. Carver, comm. Prof. L. H. Pammell.) 
Spots orbicular, 2-4 mm. diam., yellowish brown, with a 
broad almost black border, zonate; acervuli 150-200, diameter, 
covered above by the blackened cuticle, finally erumpent ; conidia 
oblong-elliptical, obtusely rounded at the ends, 14-18X6-7,, con- 
tinuous at first, becoming faintly uniseptate and mostly slightly 
constricted at the septum.
