tipper surface of the leaf-stalk presents a bleached appearance, the 
white portion being bordered by a brown line, and studded with 
very minute blackish points. These dark points represent one 
form of fruit of the fungus causing the disease, and before their 
true nature was known received the following named— Phoma 
betce, Frank, and Phoma tabifica, Prill. & Del. 
The mycelium of the fungus present in the leaf-stalks grows 
downwards until it enters the crown of the root, which is 
eventually killed ; consequently the heart-leaves also perish, the 
- ■'•> the root, where it is usually 
aided in the work of destruction by other forms of fungi, bacteria, 
eelworms, &c. 
Later in the season a second form of fruit— the ascigerous con- 
dition-appears on the dead leaf-stalks. Judging from analogy, 
the spores of this second form of fruit will remain in an 
unchanged condition until the following season, when they will 
germinate and endanger the crop.
