^■Ecidium trillii Burrill. In this species the sori are usually in circular 

 patches, the central portion free from the rust, or eating through to the upper 

 side of the leaf. 



The species is very closely allied to u^idium courallcmcia of Schweinitz. 



On Trillium sp., 6, 1894 (Golden). 

 ^Ecidium verbence Spreng. is extremely abundant. In the last season almost 

 every plant of Verbena stricta, I observed, was affected with the rust. The plants 

 grow along the roadside, and even on streets leading out of town. 



The fungus may be found on the lower leaves of the host near the ground, 

 and the ^-Ecidia occur usually in white circular spots, scattered irregularly over 

 the under surface of the leaves and producing a discoloration of the leaf.

 Cceoma agrimonia' Schw. Common. 



On Agrimonia Eupatoria, 7, 1896. 



Coleosporium hydranc/ece (B. & C. ) Only the uredospores of this species were 



found, and these seemed to be in great abundance in various parts of the county. 



The species is described by most writers under the genus Uredo, but the third 



stage has recently been found and connected with the Uredo, thus putting it in the 



proper genus. 



On Hydrangea arborescens, 9, 1896. 

 Coleosporium ipomoece (Schw.) Burrill. In this the teleutospores do not usu- 

 ally appear until late in autumn after frost. They occur in bright orange sori 

 with spores from four to six celled, cells soon separating at the septa and losing 

 their bright color.
