sporules cylindrical, hyaline, usually straight, sometimes slightly 
curved or bent, 1-3 septate, about 20 (‘‘13-23”, “ 10-27”)x3-3 %/a. 
I have labeled it Stagonospora meliloti (Lasch) Petr. 
Three collections on leaves of Acer Negundo were made in 1921 
that were referred to Septoria negundinis Ell. & Evht. They are 
evidently members of the acericolous group referred to in “Notes” 
I, pp. 81-2. In the collection from Werley the round arid spots 
are but 2 to 3 times the diameter of the usually solitary pycnidia 
and the curved sporules 32-40x1%-2 %/a indistinctly 3-septate. 
This is much like Septoria saccharina Ell. & Evht. The collection 
from Barneveld is similar with slightly greater range in spore 
length and septation not apparent. In the collection from Madison 
(Bensaude, McFarland & Davis) the spots are pale argillaceous 
with a narrow raised darker margin, amphigenous, circular to 
angular in outline, 1-3 mm. in diameter, often confluent; pycnidia 
one to few on the spot, hypophyllous, subepidermal, globose to 
lenticular, up to 180/a in diameter; sporules hyaHne becoming curved 
and 3-septate, 25-40x1%-2%/a. A collection made at Galesville 
in 1914 and recorded in “Notes” III, p. 264, as Septoria acerella 
Sacc. but belonging with these is similar, the sporules being 
23-33x1%-2%/a becoming curved and triseptate. In this collec¬ 
tion indeflnite leaf areas upon which the small spots are numerous 
become dead and brown. In examining this epiphyllous subcuticu¬ 
lar acervuli were seen bearing oblong hyaline sporules 10-13x4/a. 
These collections are evidently Septoria acerella Sacc. as treated 
by Ellis in Septorias of North America No. 160 {Journ. Mycol. 
3 : 79) but subsequently described by Ellis & Everhart as a new 
species for which the name Septoria negundinis was proposed in 
the Proceedings of the Academy of Natural Science, Phila. for 
1893, p. 165. 
Of a Septoria on Caeoma-infected leaves of Buhus allegheniensis 
collected at Madison June 2, 1921, the following notes were made: 
Spots epiphyllous, circular to angular, subolivaceous, immarginate, 
1-5 mm. in diameter, often confluent; sporules hyaline, usually 
curved, continuous, 30-50x1-2/a. While it is possible that this is 
a form of Septoria ruhi West, modified by the character of the sub¬ 
stratum it has been kept separate under the name Septoria comitata 
n. sp. ad interim. 
Septoria lycopi Pass. Collected on Lycopus uniflorus on the 
river bottoms opposite Muscoda in October 1920. This was a dry
