Ramularia Liriodendri, E. & E.—On living leaves of Lirioden- 
dron Tulipifera. Faulkland, Del., August, 1887, A. Commons. Macu- 
licolous ; spots amphigenous, ochraceous, about one-half cm. in diameter, 
with a darker border; hypbse hypophyllous, 15—40 x 3 continuous or 
1—2-septate, hyaline, tips often oblique; conidia variable, acutely ellip¬ 
tical, 5—6 x 3 !>■ or elongated, cylindrical, 12—20 x 3 /'-, continuous or 
one-septate, hyaline, ends mostly acute. On the same spots on the upper 
side of the leaves was Oloeosporium Liriodendri , E. & E. 
Ramularia rosea (Fckl.) Sacc. Syll.,III,p. 199.— Fusidium roseum , 
Fckl. Symb., p. 370.—What we take to be this species has been sent from 
Racine, Wis., by Dr. J. J. Davis, on leaves of Salix rostrata. Spots 
irregular, 1—3 millim., dark brown, almost black above, paler beneath ; 
hyphse mostly hypophyllous, fasciculate, simple or occasionally branched, 
mostly with one or two shoulder-like notches or teeth above, nearly 
straight, hyaline, 25—35 x 2—21 /*; conidia subcatenulate, fusoid, gran¬ 
ular and nucleate, 12—22 x 2 /'•. The specimens in de Thumen’s Myeo- 
theca Universalis, No. 380, seem different from this. 
Ramularia subrufa, Ell. & Holway.—On living leaves of Smilax , 
Decorah, Iowa, June, 1885, E. W. Holway, No. 376. Hypophyllous, 
occupying the areas formed by the veinlets of the leaf, soon subseriate, 
confluent, subrufous or grayish, with the margin lighter. The surface 
of the leaf in the affected parts is first overspread with a layer of inter¬ 
woven, branching, prostrate threads, sending up from numerous points 
of greater condensation fascicles of fertile hyphse, 25—35 x 3 /-*, continuous, 
but more or less denticulate or lobed above and bearing an abundant crop 
of oblong-cylindrical, concatenate, 1-3-septate (mostly one-septate). 
15—25 x 34—4 !>- conidia, obtusely pointed at the end and mostly straight, 
nearly hyaline but with a distinct yellowish tinge. The separate hyphse 
are also nearly hyaline, but in the mass both these and the conidia are 
yellowish-browm. This is an anomalous species, both on account of the 
abundant prostrate hyplue and the color of the conidia, which in all other 
respects are those of typical Ramularia. The leaf is spotted above with 
reddish-brown, becoming darker. 
Ramularia concomitans, Ell. & Holway.—On leaves of Bidens y 
Decorah, Iowa, October, 1885. Spots amphigenous, yellowish-white, 
definite, suborbicular, 2—4 millim., mostly with a narrow, dark, slightly 
raised border above; liyphse fasciculate, short, amphigenous but mostly 
hypophyllous; conidia cylindrical, with the ends subacute, one-septate 
or occasionally two-septate, 15—22 x 3—4 concatenate in series of 3—5. 
Accompanying Cercospora umbrata , Ell. & IIol. 
Cercospora gentianicola, E. & E.—On withered leaves of Gen- 
liana crinita. Faulkland, Del., October, 1887, A. Commons, No. 728. 
Tufts hypophyllous, minute, effused over a large part of the lower side 
of the leaf; liyphse brownish, simple, short (15—20 /'•) on a small tubercu¬ 
lar base; conidia subcylindrical, slightly narrowed above, hyaline, nucle¬ 
ate and faintly 2—3-septate, a little curved, 40—60 x 34
