On Aralia nudicaulis. Phlox, Wisconsin, July 11, 1914. The 
smaller and continuous sporules are probably immature but are 
in the majority in the material examined. There is evidence 
that the affected tissues fragment and fall away, for the most 
part probably, before the full maturity of the fungus. 
A collection on leaves of cultivated Phlox made at Racine, 
Oct. 1, 1896, should probably be referred to Septoria phlogis 
Sacc. & Speg. The spots have no colored border; the epiphyllous 
pyenidia are delicate; the sporules range from 25-75x 1-1 %/a. 
Apparently the spots are brown and angular at first becoming 
white or sordid and more rounded in outline with maturity. 
More or less of the distal portion of the leaves of Co-rices in 
Wisconsin are often observed to be dead and on examination 
scattered pyenidia are found. Specimens showing hyaline gut- 
tulate sporules 10-13 x 2%-3/a were referred to Phyllosticta cari- 
cis (Fckl.) Sacc. in the provisional list. Of a collection on Car ex 
sp. indet. at Racine it was noted “sporules 10-13 x 3-5/a mostly 
becoming uniseptate; some of the sporules germinate without 
forming a septum. ’ ’ A collection from Gaslyn on Car ex pennsyU 
vanica bears 1-2 septate sporules 15-16 x 4 /a ; one from Spooner 
on Car ex intumescens has biseptate sporules 16 x 4/a ; one from 
Oakwood on Carex sp. indet. shows 1-2 septate sporules 
12-18 x 4-5/a while in a collection on Carex pennsylvanica made 
at Neopit the sporules are 18-26 x 4-5/a, 3-4 septate. These 
seem to me to represent various degrees of maturity and devel¬ 
opment of a single fungus which is perhaps Stagonospora cari- 
cinella Brun. The Neopit collection bears also a Septoria hav¬ 
ing pyenidia about 100/a in diameter which contain sporules 
37-55 x i/ 2 -l/A. 
A specimen on Carex retrorsa collected at Athelstane agrees 
with the description of Stagonospora paludosa (Sacc. & Speg.) 
Sacc. 
Septoria acerella Sacc. On Acer Negundo. Galesville. This 
agrees with the description given by Dr. Martin in “Septorias 
of North America’ 7 . (Journ. Mycol. 3: 79.) 
Septoria lophantlii Wint. On Agastacke scrophulariaefolia. 
St. Croix Falls. In these specimens the sporules vary in length 
up to 80/a.
