82 BERBERRY BLIGHTS. 



patches ; but examine it with a good micro- 

 scope and the form is quite diiferent. It 

 lias nothing in common with any uredo, except 

 that it belongs to the same order. If the con- 

 tents of its spores do aifect corn, the fungi 

 must be altered by being transferred to a new 

 place of growth. It will be well worth the while 

 of the scientific reader to examine Corda's ex- 

 quisite drawing of the eecidium, in his *' Icones 

 Fungorum, or Figures of Fungi ;" he will gain 

 more by this means at a glance, than he could 

 from pages of description. The berberry also 

 is attacked by erysiphey but no uredo can be 

 conceived to arise out of the sporules of a fun- 

 gus so entirely distinct from it in every point 

 of view.
