[Vol. 8. 
Spots circular, 1-3 mm. diam., white or cream color above 
with a narrow, purplish-brown margin, rusty-brown below; acer- 
vuli epiphyllous, innate-erumpent, sublenticular; conidia cylindri¬ 
cal, 5-septate, scarcely constricted, 20-25x6-7 the terminal cells 
conical and hyaline, intermediate cells brown, the apical cell with 
a single short (6-8 /*), oblique, hyaline bristle-like crest; basidia 
simple, slender, about as long as the conidia, the riper part 
remaining to the base of the spore which in this way becomes 
bicristate. 
The conidia are not quite as broad as in P. crataegi E. & E. 
and there is no concentric arrangement of acervuli as in that 
species. The conspicuous spots in P. mali afford a striking 
and easily recognizable character. Often one or more of the 
light colored spots are included in a larger brown spot, thus 
giving the leaf a marble-like aspect. 
Ramularia hydrophylli E. & E.— On Hydrophyllum cap- 
itatum. Blue Mts. Columbia Co., Wash. April 1900. (Robert 
M. Horner, 1494.) 
Spots dark-brown, irregular in shape, 3-6 mm. long, mostly 
extending out to the margin of the leaf or occupying the tips; 
hyphae amphigenous, caespitose, hyaline, continuous, geniculate 
above and slightly toothed, 20-30x5-7 y , forming a loose white 
layer like Peronospora; conidia narrow-ovate, or elongated- 
clavate, rounded at each end, 20-30x7-10 
Cercospora simulans Ell. & Kellerm.— On leaves of Fal- 
cata comosa, Gauley Mts., W. Va. Aug. 1901. (Prof. W. A. 
Kellerman, 3775.) 
Hypophyllous: hyphae in loose, spreading tufts, geniculate 
and faintly septate, brownish, 75-100x3-4 y, forming reddish- 
brown patch 2-3 mm. diam., leaf mottled above with correspond¬ 
ing whitish or reddish subindefinite spots subangular and partly 
limited by the veinlets of the leaf; conidia clavate-oblong, hyaline, 
1-4 (mostly 3-) septate, 20-40x46,".. 
Differs from C. monoica Ell. & Holw. on the same host, in its 
hypophyllous growth and shorter, broader conidia. 
Fusarium spartinae E. & E.— On leaves of Spartina stricta. 
Pacific Grove, Cal. July 1900. (Robt. M. Horner, 1488.) 
Hyphae arising from a minute, tremelloid base, branching 
above, hyaline, forming a loose, flocculent, pale orange-colored 
growth on the lower side of the dead leaves; conidia terminal, 
oblong-elliptical or oblong-fusoid, straight, 1-3 septate, 12-15x3-4 
fj-, ends mostly obtuse. 
Diatrype megastoma E. & E.— Jour Mycol. I. p. 141, 
N. A. F. 1556, is the same as Eutypella cerviculata Fr. 
Eutypella alpina E. & E.— Proc. Phil. Acad. 425. 1895, N. 
A. F. 3331, 3436 is also Eutypella cerviculata Fr.
