Monilia crataegi Diedicke 



Parasitic on living leaves of various species of thorn bushes. It 

 causes the leaves to turn brow^n and die and is therefore more or 

 less injurious to the plant it attacks, according to the severity of 

 the attack. The fungus is at first whitish, but soon becomes ciner- 

 eous. When fresh it emits a strong odor. In the typical form of 

 the fungus the spores are said to be 13 /j- long, 11 ,"- broad. In 

 our specimens they vary from 12-20 /j- long, and 11-12 11 broad. 

 Painted Post, Steuben co. Also Clayton, Jefferson co. and near 

 Albany. May and June.
