260. Entyloma australe Speg. 
On Physalis pubescens L. Racine. 
263. Entyloma thalictri Schroet. 
On Thalictrum revolutum DC. Racine. 
269. Synchytrium aureum Schroet, 
On leaves and petioles of Pedicularis Canadensis L. 
Racine ; on Prenanthes alba L. Kenosha county. 
Only three small leaves of the former and one 
leaf of the latter were found bearing this fungus. 
The affected portions of the leaves of Pedicularis 
are curled and tinged with purple. The Pre¬ 
nanthes leaf is not distorted or stained but the 
galls are more prominent, especially on the midrib. 
On both the spots are yellow, the resting spores 
almost black, globose and lying rather loosely in 
the galls. My measurements on the former were 
160-175, on the latter 110-155 microns. 
270. Urophlyctis pluriannulata (B. & C.) Farl. 
(Synchytrium pluriannulatum (B. & C.) Earl. Suppl. 
List.) 
On leaves and petioles of Zizia aurea Koch. Kenosha 
county. 
276. Erysiphe galeopsidis DC. 
On Chelone glabra L. Kenosha county. 
279. Microsphaera alni (DC.) Wint. var. vaccotii Salm. 
On Vaccinium Canadense Kalm. State Line. 
Here also should perhaps be placed specimens on 
Kalmia glauca Ait. collected at State Line. 
Although taken in October and the asci and 
spores are well developed there are no branching 
tips to the appendages. 
293. Ascochyta pisi Lib. 
On leaves of Vicia americana Muhl. Clinton Junc¬ 
tion and Racine. 
4-celled sporules are not uncommon in these specimens 
the lateral septa being formed later than the 
median one.
