CRANBERRY DISEASES 199 
mant, are affected, in response to the attacks of the pathogene. 
They produce short shoots with leaves abnormally swollen 
and distorted. These leaves are pink or light rose-colored. 
The affected leaves stand close together and bear a slight resem- 
blance to a flower, whence the name false-blossoms. This 
name should be avoided, for there is another disease which 
passes under this designation. In the genuine false-blossom the 
floral parts are affected ; instead of the typical drooping of the 
flowers, the flower-buds stand erect, remain greenish, and do not 
set. This is accompanied by a profuse branching of the vines. 
Until recently the real false-blossom was known as “ Wisconsin 
false-blossom,’’ but in 1914 it was found in Massachusetts. 
Most plants are affected before the blossoms have developed, 
and thus the production of fruit is prevented. Later in the 
stage of development the fruiting portions of the causal fungus 
give to the surface of the distorted parts a fine, grayish, pow- 
dered appearance. 
Cause. 
The symptoms just described are changes brought about 
by the fungus Ezobasidium Ozycocci. Its mycelium grows 
within the leaf and stem-tissues, stimulating them to over- 
growth. Fruiting stalks, known as basidia, emerge and stand 
erect on the surface of the affected portion. These are found — 
from May to September, but are most abundant in the earlier 
part of the growing season. On each basidium four spores are 
borne. These bring about infections. Further points regard- 
ing the life-cycle of the fungus are not well known. 
Control. 
Since the activities and whereabouts of the pathogene are 
not clearly understood, it is almost impossible to suggest 
dependable control measures. No definite remedy is on 
record.
