N. Y. State Museum, p. 44) as infesting the seventeen-year 
Cicada, but the odspores in the latter are much smaller, being 
but 1.6 to 2u., and in one case 3.8 to 54. The same fungus was 
described briefly by Leidy (Smithsonian Contrib., Vol. v, Art. 2, 
1851), who gave the size of the spores as y to 18s. long by 7 to 
114, wide. The great difference in size between the spores in the 
species infesting Caloptenus and those in Cicada shows them to 
be distinct.—C. Æ. Bessey. 
NOTES ON GYMNOSPORANGIUM AND RÆŒSTELIA.—In my orchard 
is a row of red cedars ( Juniperus virginiana) running east and 
west. At a distance of sixteen feet north of this row of cedars 
is a row of apple trees, and at distances of sixteen and thirty-two 
feet on the south side of the cedars are also rows of apple trees. 
Mens of Reestelia. From the above statement it will be seen 
that ali the apple trees, even those standing at the same dis- 
tance from the cedars, are not equally affected, and it is to be 
which do not flourish in this locality, among which notably are 
the Baldwin and English Russett. This seems to indicate that an 
enfeebled condition of growth in a tree, renders such a tree — 
lable to the attacks of the parasitic fungi mentioned, and eee ae 
ave a direct bearing on the artificial culture of Reestelia, for al-
