Davis—Parasitic Fungi in Wisconsin — III. 269 
Cercosppra ageratoides Ell. & Evht. On Eupatorium urticae- 
folium. Galesville. In this collection the tufts are scattered 
over indefinite, but slightly discolored, spots. 
Cercospora grindeliae Ell. & Evlit. On Grindelia squarrosa. 
•St. Croix Falls. 
Cercospora absinthii (Pk.) Sacc. I am using this name to re¬ 
cord the occurrence of a Dematiaceous fungus on leaves of Arte¬ 
misia lud,oviciana at St. Croix Fails regarding which the follow¬ 
ing notes were made: eonidiophores amphigenous, scattered or 
in tufts of 2-6, more or less flcxuous, pluriseptate, brown or 
olivaceous, 90-160x4-7^; conidia apical, obclavate to obclavate- 
cylindrical, fuligineous tinted, developing about 4 septa, 30-50 x 
4-6/x,. The affected leaves show at first brown spots which be¬ 
come confluent into brown areas. The scattered distribution of 
the eonidiophores and the wooliness of the leaves make this quite 
inconspicuous. 
Frpmyces astragali (Opiz) Sacc. I am using this name for 
the purpose of recording the occurrence of uredinia on Astraga¬ 
lus canadensis at St. Croix Falls. That this American rust is 
conspecific with the European one having its aecia on Euphorbia 
Cyparissias is questionable. The Sydows in Monographia TJre- 
dinearum state that it is not while Arthur in North American 
Flora refers it to that species under the synonym Nigredo pustula 
(Schroet.) Arth. ( TJromyces pustulatus Schroet.) together with 
the Fredo on Oxytropis that has been known as Uredo oxytrop- 
idis (Pk.) De Toni. The statement of the Sydows that the ure- 
dospores on Astragalus in North America have 6-8 germ pores 
Is :pot borne out by this material in which the pores are 3-4. 
Aecidium lupini Pk. On Lupinus perennis. Millston. I am 
indebted to Dr. J. C. Arthur for the determination. In the 4th 
supplementary list mention was made of the occurrence of Tu- 
berculina persicina (Ditm.) Sacc. on Lupinus perennis as evi¬ 
dence that the host bears an Aecidium in Wisconsin winch how¬ 
ever was not collected until 1914. 
Aecidium liatridis Ell. & And. On Liatris scariosa. Solon 
Springs. 
University of VvTsconsin Herbarium, Madison, Wisconsin, 
April, 1915.
