Grateful acknowledgment is made for assistance in various 
ways by Messrs. Ellis, Arthur, Thaxter, Lloyd, and P. L. Ricker. 
As in the former Fascicle Dr. Arthur kindly inspected all the 
Uredinese, but Dr. Thaxter identified No. 44, Roestelia “globosa.”

“Ascomyces. 
“A species of this genus distorts the leaves of peaches in a most 
extraordinary way. The increase in thickness is caused by the interpo¬ 
sition of eight or more strata of parenchymatous cells between the cuticul- 
lar stratum and the oblong close-packed cells which in healthy peach 
leaves follow it. At the same time the intercellular spaces of the lower 
part are narrowed as the leaf contracts.” M. J. Berkeley. Introduction

This name, Roestelia globosa Thaxter, was perhaps first used by Ed. 
Fischer, Hedwigia, 34:4, 1895, the description having been published in 
1886 is given herewith:— 
1 urning next to R. lacerata, there seems to have been a confusion 
of tom - in this instance also. The material thus named occurring in 
America includes at least two, and perhaps three forms; one, . 
. A second form, lacerata, y in¬ 
fests the leaves of Crataegus , and does not appear until early in August; 
while a third and smaller form, lacerata, 2 , is found abundantly on Pyrus 
malus simultaneously with it. 
“In the forms y and 2 the spores are smaller, about 20 l J - in di¬ 
ameter, while the peridi. 1 cells are smaller and broader in proportion 
to their length, about 20 X 65 /a, with a tendency to a rhomboidal 
shape; the ridges are deep and sharply cut as a rule, with the striae 
clearly marked and running obliquely in two directions; those above 
the median line, where the striae are horizontal, running in a plane nearly 
at right angles to those below it. The two forms seem nearly identical
