SPHiERIA MORBOSA ScTlW. 



On the branches of plum and cherry trees. Very common and 

 injurious. This fungus is commonly called '''•black Jtnot.'"' It 

 is apparently native on our indigenous cherry trees, and, hav- 

 ing escaped from them, it has attacked the cultivated one 

 {Prunus Cerasus) in some localities with such vigor as to des- 

 troy it, and make "cherry raising" an unprofitable business. 

 Cutting away the affected branches and burning them, early 

 in the season, before the fungus has matured its s^ed, has been 

 recommended. This should be done as early as May, for I 

 have found the spores developed in June. Among our indig- 

 enous species of cherry trees, I liave found the choke cherry 

 {Prunus Virglniana) and the wild cherry {Prunus Pennsyl- 

 mmica) especially liable to the attacks of this fungus. This 

 pest is scarcely less injurious to plum trees.
