In Farlow’s Host Index this species is recorded for the follow- 
ing Cucurbits: Citrellus vulgaris (Watermelon), Cucumis Melo 
(Muskmelon), Cucumis sativus (Cucumber), Cucurbita Pepo (Pump- 
kin), and Cucurbita sp. (Squashes). 
Early last summer a serious blight of the muskmelon found at 
Port Monmouth, N. J., by the writer was traced to a Colletotrichum 
which agreed in all particulars with the one upon the bean. 
Blighted foliage of the watermelon gathered the season before 
upon examination showed the same characteristics of acervuli, 
spores and sete. A blight of cucumbers bitterly complained of 
in 1890 through the central portion of the State was due to the 
same anthracnose. 
The seemingly perfect agreement of the fungus of these three 
cucurbit hosts with the Colletotrichum of the bean suggested 
that the sete of the so-called Gleosporium Lagenarium had been 
overlooked and inoculations were made for further evidence in the 
matter. Itwas not difficult to transfer the watermelon anthracnose 
to the bean. But the points that may be of interest were the re- 
sults with a third fruit because admitting of parallel inoculations 
for both the bean and the watermelon. | 
Citrons small enough to go under a medium sized tall bell- 
jar were selected and at first inoculations were made from the 
watermelon here and there under the skin of the citron, the virus 
taking quite uniformly and growing luxuriantly. 
The Colletotrchum virus was taken from the bean and applied 
to the citron at a few points upon the side of an ink line drawn 
lengthwise of the fruit, while similar inoculations were made from 
the watermeion on the other side. Both grew with about equal 
rapidity and when prolonged the results blended showing identical 
results as shown in figure 3. In short the appearance to the naked 
eye was the same and the microscope showed no differences. The 
work was repeated with uniform results. 
Specimen No, 1173, 6. Ellis, N. A. F., were destributed as 
“ Gleosporium Lindemuthianum, S. & M., on watermelon rinds, Wis- 
consin, Sept., 1885, Prof. A. B. Seymour,” Ata later date a new ~ : 
label was issued changing the species to Glwosporium Lagenarium 
(Pass.). These specimens show an abundance of sete in the ae 
acervuli and in all points agree with the virus as above used for 
inoculation.
