The conidia are hardly distinguishable from those of P. 
guepini Desm. which is found around Tuskegee on leaves of 
Rosa, Vitis, Ulmus, Liriodendron, Sassafras and Diospyros. 
Venturia nebulosa E. & E.—On dead leaves of Era- 
grostis sp. 
Amphigenous. Perithecia ovate-globose, 75-100 a diam., 
pierced above, membranaceous, clothed with black, continuous, 
spreading hairs 30-40x3 a, seated on cloudy or smoky, elliptical 
spots 2-5 mm. diam. or by confluence more. Asci oblong, ab¬ 
ruptly contracted at base into a short stipe, aparaphysate, 35-45X 
.12-15 a. Sporidia biseriate, oblong-ovate, hyaline, uniseptate, 
slightly constricted, 12-15x5 a. 
Differs from V. erysipheoides E. & E. in its more abundant, 
shorter and narrower bristles and different sporidia and from 
Y. graminicola Winter in its broader, shorter sporidia. 
Nectria secalina E. & E.—On dead culms of Secale cereale. 
Perithecia gregarious, ovate-globose, 100-120 a diam., orange 
yellow, sometimes slightly collapsed but not very distinctly so, 
ostiolum papilliform, minute, inconspicuous; Asci clavate-cylin- 
drical sessile, aparaphysate, 40-55x7-8 a, Sporidia subbiseriate, 
oblong or oblong-elliptical, uniseptate, scarcely constricted, hya¬ 
line, 7-10x3-4 a. 
Differs from N. gibberelloides E. & E. and from N. bras- 
sicae & S. E. in its orange color and rather smaller, straight 
sporidia. 
Nectriella cacti E. & E.—On Opuntia ficus indica. 
Perithecia gregarious, bright blood-red, soft, ovate 200 a 
hig*h, no a broad. Asci sublanceolate, 45-55x4 a; paraphyses 
obscure. Sporidia biseriate, oblong, hyaline, continuous, 5~6x 
1*2 A* 
Outwardly resembles Nectria sanguniea (Sibth.) but the 
sporidia are very different; nor can it be mistaken for N. opun- 
iiae Roll, in Sacc. Syll 141632. 
Zignoella sabalina E. & E.—On petioles of Sabal adan- 
sonii. 
Perithecia superficial, gregarious or subcespitose, ovate, 
rough, collapsing, 300-350 a diam., with a papilliform ostiolum. 
Asci clavate-cylindrical, 45-60x10-12 a, subsessile, aparaphysate. 
Sporidia fusoid, subinequilateral or slightly curved, hyaline, 3- 
septate, scarcely constricted, 15-20x4^-5 a • The sporidia scarcely 
differ from those of Metasphaeria palmetto Cke. 
Laestadia prenanthis E. & E.—On living leaves of Pre- 
nanthus crepidinea. Aug. 1901. 
Spots elliptical or irregular, 3-5 mm. diam., partly limited 
by the veinlets, light brown, with a narrow, slightly raised bor¬ 
der. Perithecia hvpophyllous, scattered on the spots, semierum-
