sound grains have attained their full size and 

 maturity, when the infected grains are easily- 

 distinguished from the sound ones by their 

 being generally larger, and of a darker green 

 colour ; and if opened, they appear to be filled 

 to excess with these dark-coloured fungi. But 



A healthj' grain of wheat. A grain of wheat affected by the 

 uredo fcetida with which it is 

 filled. 



the grains infected with the uredo fcetida very 

 rarely burst, and these fungi are seldom 

 found on the outside of the grain ; but if a 

 grain be bruised, they readily emit their offen- 

 sive smell, which is worse than that from pu- 

 trid fish. When the sound grains are perfectly 

 ripe and dry, and assume their light brown 

 colour, the infected grains also change, but to a 

 somewhat darker brown, retaining, however.
