Phyllosticta caryae, n. sp.—Spots large, irregular, often confluent, at first yellowish, 
then brown, sometimes becoming grayish in the center; perithecia minute, .004 inch 
broad, punctate, epiphyllous; spores irregularly elliptical, .0002 inch long, .00008 
broad. 
Living leaves of hickory, Carya alba , Piffard, August. 
Several months afterwards Ellis and Everhart 1 described under the 
same name a Phyllosticta occurring on species of Carya at Newfield, 
N. J. On account of Peck’s priority, the specific name of Ellis and 
Everhart’s fungus was later changed by Saccardo to caryogena . 2

After examination of Peck’s material the two species were finally 
considered by Ellis and Everhart as identical, and the following descrip¬ 
tion and statement was published: 
Phyllosticta Caryae Pk, 40th Rep. 57. 1887.

P. caryogena . Sacc. Syll. 10:119. 1892. 
Exsicc. Ell. & Evrht. X. A. F. 2155, 2677. 
On various species of Carya from Maine to Kansas. 
Spots large, irregular, often confluent, often acute at each end, with a nerve of the 
leaf running through the center, .5-1 cm. diam., yellowish at first, becoming brown,
