TAUBENHAUS ON A PECULIAR DISEASE OF MULBERRY FRUIT 285 



are held glued together in a gelatinous substance probably secreted 

 by the causal fungus itself. 



Immediately upon the maturity of the fruit, the so-called 

 "popcorn seed" from the mulberry fruit drop to the ground. 

 After a few days, or possibly weeks, the outer coat of these seed 

 falls off, leaving a black pebble-like structure the size of a popcorn 

 seed or smaller. These black bodies, known as sclerotia, consist 

 of a mass of fungus threads. These sclerotia when dropping to 

 the ground, lie there until the following season. 



The thing which has not as yet been worked out about this 

 disease is the significance of the minute spores previously de- 

 scribed and the purpose of the sclerotia. In other words, how do 

 new infections take place? Is it through the wintered-over 

 sclerotia or through the minute spores formed on the deformed 

 mulberry seed? When these two questions are answered, it is 

 reasonable to suppose that the identity of the fungus and the 

 history of the disease will be worked out, and methods of control 

 determined. 



If one examines trees which are affected with the "popcorn" 

 disease, he will notice in many cases a die-back of the twigs Wheth - 

 er this die-back is in any way related to the mulberry fruit 

 disease is still unknown.

The radiant and golden stars depart, 

 The velvet sky and silver moon retreat 

 Before the heavy, threat'ning clouds that greet 



The gloom, and banish ecstasy of heart. 



The rose, sweet, fragrant not long since in bloom, 

 And arbutus whose scent's been created 

 To ma tell the clear, pale-husd pearl, have faded, 



And give no more their heavenly perfume.
