September and the spores are smaller than indicated in the de¬ 
scription. 
For the parasite recorded in ^ ‘ Notes V, p. 696, under the name 
Lophodermium lineare Pk. (Ehytisma lineare Pk., Hypoderma 
lineare Pk.) von Hoehnel has proposed a new genus, Bifusella (Ann. 
My col. 15:318-19.) 
In ‘‘Notes” IV pp. 683-4 reference was made to a group of 
variable Sphaerioidaceae on Atriplex and Chenopodium members 
of which have been referred to Phyllosticta, Ascochyta, Diplodina, 
Septogloeum, Stagonospora, Phleospora and Septoria and to the 
reference of the group as a whole to Stagonospora atriplicis West, 
by Lind and to Septoria chenopodii West, by Grove. In a discus¬ 
sion of some members of this group by J. B. Ellis the conclusion 
was reached that “This variability would seem to strengthen the 
supposition that all the forms here enumerated may be referred to 
Septoria (Phyllosticta) atriplicis Desm. ” {Journ. My col. 4:117-18 
[1888].) A parasite collected on Chenopodium album at Cary- 
ville July 21, 1921, appears to be an extreme variant of this group 
because of the long and slender sporules. The following notes 
were made: Spots suborbicular, immarginate, light yellow to yel¬ 
lowish green, averaging about % cm. in diameter; pycnidia 
amphigenous, scattered evenly over the spots; sporules discharged 
in colorless cirri, hyaline, straight or curved, 1-3 septate, 
24-67x2%-3%/>t. The sporules often appear continuous in a water 
mount. Apparently they are catenulate, their length depending 
upon the number of abstrictions of the primary sporule. 
In a collection of Septoria aquilegiae Penz. & Sacc. from Durand 
(July 12, 1920) the sporules are mostly about twice the typical 
length but without noticeable increase in diameter. 
Septoria ampelopsidis Ellis appears to be a better developed 
state of the parasite recorded in the provisional list under the 
name Septogloeum ampelopsidis (E. & E.) Sacc. This form with 
definite pycnidia and long and slender sporules has been collected 
on Psedera at Madison, Wausau and Durand. I have labeled it 
Septoria ampelopsidis (E. & E.) Ellis. 
In a collection of Septoria on Cicuta maculata made at Weyer¬ 
haeuser, September 9,1918, the pycnidia are borne on small (1 mm. 
or less) subcircular white arid spots having a dark reddish brown 
border; the globose pycnidia are 80-85/x in diameter, the sporules
