Pig. III.—Bean pods affected with Anthracnose or Pod Spot (After Whetzel,. 
Bulletin 255, Cornell Experiment Station) 
the causal fungus, Colletotrichum lindemuthionum. has been carriedl 
over winter in the seed. 
In due course of time, spores, by means of which the disease is> 
spread, are produced in these early spots. Eventually they are blown,, 
or otherwise carried, to the growing stems, leaves and pods, where 
they soon become established and begin their destruction.
