Cercospora varia Pk. On Viburnum pubescens. Brnce. In 
this collection the conidiophores are 20-30 x 4-6/*, the conidia 
60—130 x 3 u- The fasciculi are mostly epiphyllous. As remarked 
by Ellis and Everhart (Jour. My col. 1:63), this seems doubt¬ 
fully distinct from C. tinea Sacc., but I have not seen European 
specimens. The petioles of the leaves of the host in this collec¬ 
tion are 2 cm. long. 
Cercospora helianthi Ell. & Evht. On Helianthus strumosus. 
Nekoosa. In a collection on H. occidentals from the same lo¬ 
cality, the conidiophores are mostly epiphyllous on small, im- 
marginate purple spots. 
Entyloma crastophilum Sacc. On upper leaves and axis and 
branches of the panicles of Glyceria pallida. Chetek. This is 
the only indigenous grass upon which I have seen this species. 
Uromyces fabae (Pers.) DBy. Uredinia and telia on Vida 
caroliniana. Fish Creek. Aecia and uredinia were present on 
Lathyrus palustris in the same locality but on the opposite side of 
the bay. Uredinia on Vicia caroliniana. Nekoosa. 
Telial material of Uromyces acuminatus magnatus (Arth.) on 
Spartina Michauxiana collected at Hancock in October, 1918, and 
wintered out of doors infected Smilacina stellata y S. racemosa , 
Polygonatum commutatum, P. biflorum, and Oakesia sessilifolia in 
the greenhouse in May, 1919. Uvularia grandiflora and Conval- 
laria majalis proved immune. Two plants of Oakesia were 
brought in from the woods and exposed to infection. One was 
a vigorous, growing plant having seven leaves. Every leaf of 
this plant was thoroughly infected, as shown by the abundant 
spermogonia, with the result that they withered and died without 
forming aecia except at the base of the lowest leaf. The other 
plant was stunted, having but three leaves which seemed old and 
firm. This plant was but slightly infected, but bore aecia on a 
spot on one of the leaves. 
Having some overwintered telial material of Puccinia stipae 
Arth. on Stipa spartea which germinated with unusual vigor, a 
young plant of Aster multiflorus was brought into the greenhouse 
and exposed to infection. The result was thought to be nega¬ 
tive, but before discarding the Aster plant it was examined care¬ 
fully and two very small aecial spots were found, one bearing one 
cup, the other three. These spots were on the leaf edge.
