Davis—Parasitic Fungi in Wisconsin — III. 253 
Phomopsis vexans (Sacc. & Syd.) Harter is the name given 
by Harter to the fungus recorded in the provisional list under 
the name Phyllosticta hortorum Speg. (Journ. Ag’l Research 
2:338). 
The Septoria which occurs on Agrimonia in Wisconsin bears 
smaller sporules than the Septoria agrimoniae-eupatorii Bomm. 
& Rouss. of Europe as described. They are usually 25-40 x 1/*.

There is considerable variation in the appearance of Septoria 
on Echinpcystis in Wisconsin. The spots are commonly small, 
round and arid such as are attributed to Septoria sicyi Pk. and 
S. brencklei Sacc. Sometimes, however, they are angular, inter- 
venular, green becoming brown. This is more nearly the kind 
of spot described under Septoria echinocystis E. & E. Both 
types of spot are sometimes found on the same leaf. Dr. R. A. 
Harper kindly compared a Wisconsin specimen with green to 
brown angular spots with the type of Septoria echinocystis E. 
& E. in the Ellis herbarium and wrote as follows: “The spores 
agree as to size etc. The spots in the type are larger, more 
brownish in color and rounded with a well defined center. It 
seems however that it ought to be the same thing.” (In lit. 
Apr. 30, 1914) As these two kinds of spots intergrade I cannot 
consider them as due to specific distinctness of the infecting 
agents but rather as shade and moisture forms on one hand and 
the results of sunshine and dry air on the other, the latter con¬ 
ditions favoring a process of delimitation. As to the size of the 
sporules I find them to range from 20-60 x 1—2/x. In the form 
with round arid spots they are usually shorter than in the one 
with angular green-brown spots. For instance in a collection 
that could be referred to S. brencklei Sacc. most of the sporules 
are about 36/* long with an extreme length noted of 48/*. The 
collection of the S. echinocystis type from which a specimen was 
sent to Dr. Harper for the comparison has sporules 35-55 x 
1-1%/*. There seems to be no reason as yet for changing the 
record of these forms from Septoria sicyi Pk. 
The entry Septoria stachydis Rob. & Desm. in the Wisconsin 
lists seems to have been founded upon immature specimens of 
another fungus. 
In returning a portion of the type specimen of Septoria inter¬ 
media E. & E. Mr. Ellis wrote as follows on the packet: “There
