cultivation was abandoned. 
SYCAMORE BLIGHT.* 
The Sycamore disease due to Gloeosporium nervisequum appeared sud¬ 
denly at Dover, Del., between May (3 and 14. A special examination of 
a large tree was made on the iirst date to discover the blight, because 
it had appeared on the tree in previous years. Not a trace was found, 
but having occasion to pass the same tree a week later, dozens of 
blighted shoots and dead and drooping leaves were found on all parts. 
Immediately preceding this attack came a cold snap. On the morning 
of the 4th there was a white frost, on the 5th it was very cold, with a 
black Irost at night, which destroyed the peach crop on flat lands. On 
the 6th it was still colder with a fall of hailstones. Following this and 
during the week in which the blight appeared came a hot spell. It was 
very warm on May 9, 10, and 11. 
NEW FUNGOUS DISEASES OF IOWA. 
By L. H. Pammel. 
The following paper treats mostly of new diseases of plants, but ref¬ 
erence will also be made to a few that have been the subject of recent 
papers. Its scope will be limited to such diseases as have been destruc¬ 
tive to farming and horticultural interests during the past year in Iowa, 
since to do justice to the subject over the whole country would take too 
much time and space. 
The subject can naturally be divided as follows: 
I. Fungi affecting forage plants and cereals. 
II. Fungi affecting fruits and fruit trees. 
III. Fungi affecting forest trees. 
To the farmer in Iowa the diseases under the first head are of the 
greatest importance since the wealth of the State depends largely upon 
successful grain and forage crops. 
I.—FORAGE CROPS AND CEREALS. 
Diseases of wheat. —Aside from the usually common grain rusts (Puc- 
cinia graminis , and P. rubigo-vera) a serious disease of the wheat lias 
appeared in the so-called u blight,” or u scab, ” as the disease is called in 
different parts of the country. This disease causes the upper part of the
