49. Erysiphe communis, (Wallr.) Fr. 
On Astragalus Canadensis, L., Aquilegia Cana¬ 
densis, L., and Geranium maculatum , L. (Tracy 
and Galloway, Ice. cit .) Thalictrum purpurascens, 
L. Racine. As noted above (No. 47) Clematis Vir- 
giniana , L.. should probably be added as a host 
of this species in Wisconsin. 
67. Claviceps, sp. 
Sclerotia also on Juncus nodosus , L., and 
Glycerict fluitans , R. Br. Racine. 
69. Hypocrella, sp. 
Dr. Trelease writes that this is directly parasitic on the 
leaves. 
77. Microstroma leucosporum, Mont. “Represented” on Jug- 
Ians cinerea , L., “from just across the line in 
Minnesota and Illinois, and hence certain to be 
found in Wisconsin. It should also occur on 
Cary a. ” (Prelim. List.) 
It occurs at Racine on both Juglans and Cary a, and at Lake 
Geneva on Juglans cinerea, L. The form on Juglans has been 
separated as Microstroma juglandis, (Bereng.) Sacc. 
78. Ramularia didyma, Ung. 
On Ranunculus repens, L. (?) Racine. So la¬ 
belled before R. septentrionalis, Poir., was differ¬ 
entiated and is likely the latter. 
80. Ramularia plantaginis, E. and Martin. 
On Plantago Rugelii, Dcsne. Racine. 
82. Ramularia arvensis, Sacc. 
On Potentilla Anserina, L. Bassett. 
83. Ramularia macrospora, Fres. var. asteris, Sacc. (Var. 
senecionis, Sacc. Prelim. List.) 
Dr. Trelease states that the varietal name should be as given 
above. Occurs also at Racine on the same host. 
89. Ramularia desmodii, Cke. 
On Lespedeza, sp. Racine.
