Dec. 3 , 1917 Temperatures of Cranberry Regions and Plant Growth 529 
(5) The fungus diseases of the cranberry have, in general, proved the 
most serious and destructive in regions with long growing seasons, 
combined with high summer temperatures. This applies particularly 
to the diseases caused by Glomerella cingulata , Guignardia vaccinii , 
and other fungi having similar temperature relations. 
(6) Certain other cranberry fungi, notably Fusicoccum putrefaciens, 
are, on the contrary, more abundant in regions which have only short 
periods of high temperature—that is, periods having daily mean tem¬ 
peratures of 6o° F., or above.
