SPH ERIA MORBOSA Schw. 
On the branches of plum and cherry trees. Very common and 
injurious. This fungus iscommonly called ‘‘ black knot.” It 
is apparently native on our indigenous cherry trees, and, hay- 
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 seed, 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 have found the choke cherry 
(Prunus Virginiana) and the wild cherry (Prunus Pennsyl- 
vanica) especially liable to the attacks of this fungus. This 
pest is scarcely less injurious to plum trees.
