RE-EXAMINATION OF THE MYCOSPHARELLA WILT 
OF MELONS IN 1908. 
Introduction.—Both the red spider and the Mycospherella 
wilt reappeared on muskmelons in the same greenhouse in 1908. 
The soil used on the melon benches in 1907 was removed in 
September, exposed to the weather, but returned to the same 
benches in March, 1908. The house was thoroughly fumi- 
gated with hydrocyanic acid gas before the plants were intro- 
duced. They were benched about two months earlier than in 
1907. | 
The appearance of other parasitic fungi.icmWhen the melons 
were about two-thirds grown a Coremium-like fungus was found 
attacking two vines a few inches from the ground and destroy- 
ing the cortical tissues on a short region of the stem. The fun- 
gus produced large quantities of spores but failed to infect other 
plants. The two affected plants neither wilted nor evidenced 
harmful effects, yet each had a girdle of destroyed cortical tis- 
sues. A Sclerotinia, probably Sclerotinia Libertiana Fckl., 
proved a more virulent parasite. The parasitized vines had an 
oily-green, water-logged appearance, and occasionally a few 
drops of exuded, resin-colored gum. By the presence of fluffy, 
aerial mycelium, later forming sclerotia, and by the entire 
absence of any fruiting bodies on the affected stems, it is easily 
distinguished from Mycospherella wilt, though it may cause 
partial wilting of the vines. Comparatively little damage was 
done by this fungus. : 
Occurrence of the red spider.—The red spider became evident 
shortly after the appearance of the Sclerotinia; it was sprayed 
with water as in the previous season and readily controlled, 
though some leaves turned yellow. 
Reappearance of the Mycospherella wilt.—About the time 
the first melon fruits had attained full size, the Mycospherella 
wilt reappeared; being about a month earlier than in 1907. 
On June 23, three vines were found to have some of their lower
