4ECIDIUM LEUCOSPERMUM DC, 
By Henry T, Sopprrr. 
Dourive the spring months of the past four years I have given 
some little study to AHeidium leucospermum, which is parasitic on 
mmon 
own experience of 
Puccinia fusca is that it one of the commonest of British 
Uredinee, and I have noticed that it makes its appearance long 
before the Acidium. 
Steeton, some ten miles distant, and a few weeks later on at Bolton 
view to observing whether the Acidium was succeeded by any other 
spore form ; and on several occasions later in the season I revisited 
the localities, but failed to find the slightest trace of uredospores or 
teleutospores either on the same host or on any other species of 
plant in the vicinity. 
or the purpose of experiment, during the following spring 
I collected a quantity of Puccinia fusca, which was kept during the 
winter out of doors under a bell-glass. At various times during 
April, 1891, the spores were placed in water, and repeatedly 
examined, but in not a single instance did I observe germination. 
The spores, however, were subsequently applied in quantity to 
healthy Anemone plants, but no result followed. 
In the middle of May, 1891, I transplanted into my garden from 
Steeton several plants of Anemone nemorosa, the leaves of which 
sequent cultures—did it become detached, or attempt to germinate. 
On May 24th, 1891, I had an abundant supply of spores of the 
JournaL or Borany.--Vou. 31. [Srpr. 1893.] T
