Hawkins and Bruce. August and September. There are some¬ 
times a few galls on the lower leaf surface, especially on the veins 
and sometimes on the petiole. 
[In examining stained microtome sections of fixed material of 
this species Miss Dorothy Bradbury and Dr. E. M. Gilbert, under 
whose direction she was working, detected summer sori. The galls 
are hypophyllous, prominent, globose, 150-185/* in height and 
breadth with walls three cells thick proximally, thinning out dis- 
tally; sporangia probably about 30, spherical to elliptical to poly¬ 
hedral, averaging about 20/* in diameter.] 
Yenturia has been observed on leaves of cranberries and blue¬ 
berries in Wisconsin, but as the material collected was not ma¬ 
ture, no determinations and records were made. Shear has re¬ 
ported Venturia compact a Pk. as occurring on cranberry leaves in 
Wisconsin (Bur. Pit. Ind. TJ. S. Dept. Agr. Bull. 110: 45). 
Traces of Taphrina ulmi (Fckl.) Johans, were observed in 
June, 1918, on leaves of elm shoots growing along the railroad 
track in Madison. It has not been seen since. 
Septoria polaris Karst. 
On radical leaves of Ranunculus rhomhoideus . Plover and Wild 
Rose. Of one of the collections referred here the following notes 
were made: Spots orbicular to elliptical, brown becoming pallid 
with a brown border, 2-8 mm. long, sometimes confluent; pycnidia 
epiphyllous, often numerous, scattered, black, globose to ovoid, 
80-130/* in diameter; sporules filiform, straight or more often 
somewhat curved, continuous ( ?), 24-36 x 1/*,. This is the parasite 
issued under this name in F. Columbiani 4878 and F. exot. exsicc. 
434. It seems closely allied to S. ficariae Desm. S. ficariaecola Sacc. 
S. cymbalarina Thuem. and S. ficarioides Pk. 
[Since collected also at Caryville] 
Septoria hydrocotyles Desm. 
On Hydrocotyle americana. Wild Rose and Wautoma. 
Septoria coreopsidis n. sp. 
Spots circular or marginal and semicircular, cinereous with a 
raised margin surrounded by a dark purple zone, 1-2 mm. in 
diameter; pycnidia punctate, black, scattered, innate, globose, 
60-90/*; sporules, hyaline, somewhat curved, sometimes guttu-
