Davis—Notes on Parasitic Fungi in Wisconsin — IV. 685 
3-septate; Stagonospora compta (Sacc.) Died. (Septoria 
compta Sacc.) 15-25x4-5/*, pluriguttulate or 4-5 septate. 
The economic importance of the clovers js such that we may 
anticipate that intensive work will be given to their diseases 
and the nomenclature may perhaps be allowed to rest until that 
is done. 
Septoria sigmoidea Ell. & Evht. On Panicum virgatum. 
Lynxville. In these specimens the pycnidia are borne in long 
dead leaf areas. The sporules have a fuligenous tint and are 
little more than 3/* thick. 
Septoria glumarum Pass. On dead, rusted leaves of Triticum 
vulgare (cult.) Athelstane. Sporules 15-36 x 2%-3/a, 1-3 
septate as shown by staining. In a collection made at Inde¬ 
pendence July 29, 1916, the pycnidia are sometimes accompanied 
by perithecia that seem referable to Sphaerulina. 
Septoria nematospora n. sp. Spots lamphigenous, indeter¬ 
minate, pale yellow becoming brown, 3-6 mm. long and 
of the width of the leaf, often confluent; pycnidia hypophyllous, 
intervenular, dark brown, ostiolate, globose to elliptical, 75-150 
x75-100 /a; sporules filiform, somewhat curved, lax, continuous, 
eguttulate, 37-55 x 1/2-V* On leaves of Car ex pennsylvanica. 
Ladysmith, Wisconsin, July 31, 1915. This was referred to in 
“Notes” III, p. 246. While examining the Ladysmith col¬ 
lection a pycnidium was observed which contained sporules 
18-20 x 3-4/*, 3-septate like those noted in the same reference. 
Septoria anemones Desm. On Anemone quinquefolia. 
Racine. On longitudinal blackish brown areas associated with 
an immature Sphaeriaceous fungus. 
On looking over some unidentified collections I find one on 
cultivated Chrysanthemum made at Racine May, 1894, by F. 
L. Stevens which I refer to Septoria rostrupii Sacc. & Syd. 
The spots are mostly green, the black, epiphyllous pycnidia 
about 90/a in diameter and the sporules 42-48 x 1-2/*, subflexuose^ 
This is given as a synonym of Septoria chrysanthemella Cav. on 
the label of Vestergren’s Micromycetes rariores selecti 1646. 
Specimens from an elm in a city lot at Platteville bear 
Sacidium ulmi-gallae Kell. & Sw. They were sent by Mr. S. 
E. Livingston. The sporules are mostly oval to ovate, 6-9 x4/*. 
The host is Ulmus fulva and the accompanying galls are those 
caused by Schizoneura americana as I am informed.
