flowers, and often causes abortion of the fruit. The 
spots are round depressed black, with a white mem- 
braneous margin, formed from the cuticle of the fruit. 
The black portion is a compact mass of spores of the 
fungus growing underneath the cuticle. These grow 
continuously, and as they grow they tear open the 
cuticular membrane, and the mycelium, which lives and 
feeds upon the juices of the fruit, burrows into the 
flesh and causes cracks. The cracks, at first slight, 
become at length confluent, finally produce deep fissures, 
which, exposing the substance of the fruit, causes it to 
rot.”
