New YorkK AGRICULTURAL EXPERIMENT STATION. 187 
the foliage was killed. In 1900 our first observations were made 
May 10. At that date the flower buds were unopened and only 
a few leaf buds broken, but it was even then evident that the 
trees were considerably injured. On many branches the ma- 
jority of the buds were dead. The wood of the preceding year’s 
growth was frequently dead, or, if living, was badly discolored. 
Further observations were made May 21, when the trees were in 
bloom. Many flower buds failed to open; those which did open 
were belated, the flower pedicels were quite generally shortened 
and a large percentage failed to set fruit. We are informed 
that there was a light crop of fruit. 
In an orchard at Hector the leaf scorch in 1899 affected only 
the south half of each tree. In the spring of 1900 we found that 
the flower pedicels on the south side of these trees were abnor- 
mally short, the flowers often being almost sessile; while on the 
north side they were considerably longer and nearly normal. 
A New Funeus on Cuerry Brancues (Cryptosporium cerasinum 
Pk.).—In the vicinity of Geneva dead cherry branches are fre- 
quently infested by a species of Cryptosporium. Specimens were 
submitted to Prof. C. H. Peck, who informs us that the fungus 
is an undescribed one and that he proposes to call it C. cerasi- 
mum. It is probably not parasitic. Its spores resemble those 
of the cherry leaf-blight fungus, Oylindrosporium pad. 
ENLARGEMENTS ON THE Branoues.—Occasionally cherry 
branches show barre]-shaped enlargements of various sizes. On 
the Station grounds there is a Chinese double-flowering cherry 
which is seriously affected in this way. The enlargements are 
numerous on all branches more than three years of age, and oc- 
cur even on the trunk. One branch four feet long bears nine 
enlargements. They are produced by an abnormal thickening 
of the bark which is dead and brown and often deeply scarred 
by wide, rough longitudinal slits. (See Plate XXIV, Fig. 1). 
The cause of the enlargements is unknown To us. 
OruER Dispasps.—There has been a little powdery mildew, 
Podosphera oryacanthe, on nursery stock and occasionally on the 
tips of twigs on bearing trees; but it has not been destructive.
