New Yorx AGRICULTURAL EXPERIMENT STATION. 181 
An experiment was made to determine if bruises made after 
the fruit was ripe would cause the appearance of starch in the 
bruised tissue. On December 6, apples of the variety Pride of 
Texas were bruised without breaking the epidermis, and then 
kept at a temperature of 60°F. At the end of three weeks the 
bruised tissue contained a little starch, but the quantity was very 
small as compared with that found in old bruises on the same 
variety. 
V. A FUSARIUM LEAF-SPOT OF CARNATIONS. 
A very unusual case of Fusariwm attacking carnation foliage 
was observed in a greenhouse at Syracuse last November. A 
bench of carnations of the variety Emily Pierson was quite 
seriously affected with a peculiar leaf-spot. The spots varied in 
length from one-eighth of an inch to one inch. The smaller ones 
were elliptical, but the larger ones occupied the entire width of 
the leaf and were irregular at the ends. They were covered with 
a pinkish gray mold and irregularly dotted at the center with the 
light yellow spore masses of a species of Pusariwm. Many of the 
worst affected leaves were dying. The FMusariwm was evidently 
parasitic on the leaves, but a careful examination revealed the 
fact that in every case the spots originated in a rust™ sorus. It 
appeared that the Fusariwm was unable to attack the uninjured 
leaf, but when the epidermis was broken by rust it was able to 
enter and bring about decay of the leaf tissue. It is improbable 
that the Fusarvwwm is parasitic upon the rust.” 
The writer has occasionally observed Fusarium attacking 
injured leaves and stems of carnations and the spore masses of a 
similar Musarium are common on the stems of carnations affected 
24 Uromyces caryophyllinus (Schrank) Schroet. 
25 In this connection it may be mentioned that Mr. F. H. Blodgett, Assistant 
Botanist and Entomologist, observed at Mattituck, N. Y., last August, a 
Fusarium growing abundantly on the uredo sori of Puccinia asparagi, D. C. 
However, in this case, the Fusarium was not confined so strictly to the rust 
sori, but occurred also upon the so-called leopard spots and sometimes even 
upon the uninjured asparagus stems.
