REPORT OF THE BOTANIST. 77 
SPHARIA CoLutnsit Schw. 
This occurs in the Adirondack region on leaves of Spiraea 
salicifolia. The branches in this as in Amelanchier Canaden- 
sis are swollen and distorted by the fungus. 
VENTURIA MACULANS Pk. 
I am satisfied that this is only a form of Sphaeria ditricha 
Fr., a species which has been referred to Spheerella, though in 
my opinion it is a good Venturia.
