According to the following account, which accompanied the 

 specimens, this parasite threatens to become a serious pest unless 

 promptly arrested. " It is found that not all varieties are attacked • 



most 



attack. The present season has been an extremely wet one I 

 have come across it before, but this year it appears to have been 

 much more severe. Last year (the driest on record for 22 years) 

 only very few leaves were seen to be affected." 



The entire upper surface of the leaf is often covered with 



Mass 



and general appearance, but differing in the smaller spores.
