Septoria pentstemonicola E. & E.— On leaves of Pents- 
temon gracilis. Aberdeen, South Dakota, July, 1896. (David 
Griffiths.) 
Spots subindefinite, 2-3 mm. diam., brown, soon confluent 
giving the leaf a dried up, dead appearance. Perithecia puncti- 
form, minute (75 p), scattered over the leaf and not confined to 
the spots. Sporules filiform, slightly curved, faintly nucleolate, 
30-45x1-i^ fi . 
Differs from S. pentstemonis E. & E. in the character of the 
spots and in its longer sporules. 
Septoria corydalis Ell. & Davis.— On leaves of Corydalis 
glauca, Vilas Co., Wis. July, 1901. (Davis No. 019.) 
Spots white, transparent, definite, surrounded by a reddish- 
brown halo, roundish or irregular, 2-6 mm. diam. Perithecia 
few, black, visible on both sides of the leaf but more distinct 
above, sporules cylindrical, 3 - 5 XI -2 p . 
Septoria liatridis Ell. & Davis.— On leaves of Liatris spi- 
cata, Racine, Wis. June, 1901. (Davis 013b) and L. scariosa 
(013)- 
Spots round or elliptical, 2-4 mm. diam., of a dirty brown 
color, with a narrow slightly raised margin, finally thin, white 
and transparent; perithecia innate, more prominent above, small 
75-80 p . Sporules filiform, continuous, hyaline, nearly straight, 
20-30 x ij-ij p. 
Zythia rhoina E. & E.— On dead stems of Rhus radicans, 
Newfield, N. J. May, 1900. 
Perithecia cespitose, ovoid, light yellow, 150x200 //, surface 
slightly granular-roughened, astomous, collapsing to cup-shaped, 
clustered on a rather soft, tubercular, yellowish stroma about 1 
mm. diameter and outwardly not distinguishable from a Nectria. 
Sporules oblong-elliptical, hyaline, continuous or faintly unisep- 
tate, 6-10x24-3-!//, on slender basidia mostly a little curved and 
permanently attached, 8-15 p long. 
Cylindrosporium infuscans E. & E.— On leaves of Ely- 
mus condensatus. Waitsburg, Wash. Oct. 1899. (Robt. M. 
Horner, No. 1406.) 
Acervuli innate, black outwardly, elliptical, 100-110x120-150 
p, erumpent above, seriate between the nerves of the leaf; con- 
idia lanceolate-cylindrical, straight or slightly curved or bent, 
continuous or slightly curved; hyaline with a slight yellowish 
tinge, 40-55x3-4 p .' 
The fungus gives the upper side of the leaf a dark smoky 
hue, but there are no spots.
