CLASSIFICATION OF THE UREDINES. 
The Editor has said more than once that controversies upon 
matters mycological lead to no good; and, believing him to be 
right, I will only say that I have read carefully his remarks on p. 
151. During the past summer I have been working at the 
physiology of the Uredines, and although I do not intend here to 
give the details of my experiments, I wish to point out — 
(1) That the teleutospores of Uromyces poce, Rbh. which pre- 
viously had not been met with in Britain, have been found 
abundantly this year on Poce trivialis and P. pratensis wherever 
their grasses grow near ^cidium ficarise. 
(2) That the ^cidium upon Ranunculus repens is connected 
with Uromyces poce^ and not, as was stated in my paper, with 
Uromyces dactylidis. 
(3) That u^cidium rumicis is connected with Puccinia arun- 
dinacea ; and that the jEcidium has followed the infection with 
Puccinia Arundinacea spores upon Rumex obtusi/olius, crispus, 
hydrolapathrum and conglomeratus, and upon the common rhubarb. 
(4) That up to the present time sowing the spores of P. 
arundinacea and P. SJ agnusiam on Rumex acetosa has with me 
produced no iEcidium. 
(5) That as no Puccinia occurs on gooseberry leaves in this 
country it is clear jEcidium grossularice, as we find it, is not a 
Pucciniopsis, but is probably a heteroecismal species.
