Lind unites these, with ( other forms, under the name Stagonos- 
pora atriplicis (West.) Lind. (Danish Fungi 2387 p. 444.] 
Grove uses Septovia chenopodii West: for the group. ( Journ. 
of Bot. 55: 348) 
Stagonospora typhoidearum (Desm.) Sacc. On leaves of 
Typha latifolia. Mountain. Sporules 15-20 x 4-5 /a about 
4-guttulate. Cytoplasm 1-3 times divided when treated with 
iodine. Hendersonia typhae Oud. which has been collected on 
Typha at Madison is perhaps parasitic. 
Stagonospora dearnessii Sacc. On Trifolium repens. Madi¬ 
son and Athelstane. In these collections the sporules are 1-sep- 
tate with occasional 2-3 septate ones. The young sporules con¬ 
tain 6-8 small guttulae which are larger and 4 in number when 
the septum is formed and probably disappear at maturity. I 
find the sporules to be uniformly triseptate when brought to 
germination. In the original'description (Stagonospora trifolii 
Ell. & Dearn. Phila. Acad. Sci., 1891, p. 82) the sporules are 
given as 2-4 nucleate but nothing is said of septa. Since this 
was written a collection has been made on Trifolium hybridum 
(Hixton, July 7-1916) with sporules 9-14 x 3/a, uniseptate, 
rarely biseptate. They are somewhat fusoid while those that 
I have seen on T. repens are cylindrical or even somewhat nar¬ 
rowed in the middle. Of what I take to be a state of this 
fungus the following notes were made: Spots lethal brown, im- 
marginate, elliptical to oblong or triangular, sometimes con¬ 
fluent, 3-10 mm. long, the long axis being parallel to the veins; 
pycnidia hypophyllous, scattered, succineous, widely open, 
about 100/a in diameter; sporules mostly bacillary, 3-6 x 1-1%/* 
but occasionally ovoid, 2-3x1%/*. Oconto Co., June 25, 1915. 
It may be that Phyllosticta trifolii Rich, and Phyllosticta Trifo- 
tiorum Barbarine were founded upon something like this which I 
take to be a spermogonial condition very similar to Sporonema 
phacidioides Desm. on Medicago. 
Gloeosporium trifolii Pk. (See p. 674) and Stagonospora 
dearnessii Sacc. I take to be congeneric if indeed they are not 
more closely related as they may be to the following forms on 
clover that have been described: Phleospora trifolii Cav. with 
sporules 16-18 x 4-5/a, continuous or with 1-3 indistinct septa 
and var. recedens C. Massal. 16-24 x 5-5%/a 1-3 septate; 
Ascochyta trifolii Siemaschko, 18-20 x 5-6/* with one or rarely 
2-3 septa; Ascochyta trifolii Boud. & Triouss. and Ascochyta 
confusa Bubak said by Jaczewski to be probably conspecific 
with the foregoing; Stagonospora trifolii Fautrey, 16-22 x 3-4/a,
