ON ANTHRACNOSE — A NEW DISEASE OF THE VINE. 
By Dr. Maxime Cornu.* 
The vineyards of the Narbonne district have been attacked this 
year by a new disease, caused by a special Fungus, which, I believe, 
with Monsieur Planchon to be identical with the jPhoma uvicola. + 
This disease, which has received the name of anthracnose, is 
characterised by its peculiar effects on the boughs and leaves, and 
on the grapes. This parasite produces on the grapes a circular 
spot — black, as if burnt — in the middle of which a smaller white 
circle is seen, formed by the development of the conidiiferous form 
of the fungus. 
On the stem, these black spots become depressed circles ; the 
stem appears corroded and burnt through to the woody tissue, 
sometimes to the pith ; it is this peculiar effect which has caused 
the disease to be sometimes designated by the characteristic name 
of “ Chanchre ” ^canker). On the leaves, spots of different sizes 
are seen, more or less confluent, formed by the dried-up tissue 
which has been affected by the influence of the parasite. 
I have received from Monsieur Blavet, President of the Society 
of Agriculture of Etampes, leaves and bunches of grapes, showing a 
disease which has alarmed the vinegrowers of that district. The 
grapes, scarcely ripe, showed circular black spots, which appeared 
to radiate from the point of attachment of the grape ; the leaves, 
partially dried up, were covered in some places rather abundantly 
with a brown mould.
