correctness of the determination, upon a comparison of our speci- 
mens with authenticated ones received from the late Dr. Curtis.

Exopastpium AzALE& Peck. 
the 
Gall subglobose, often lobed or irregular, succulent, fleshy, 
solid, smooth, pale green or glaucous, becoming pruinose ; spores 
oblong, straight or curved, obscurely uniseptate, white, .0006— 
.0008 in. long. 
Terminal on living branches of the pinxter plant, Azalea nudi- 
flora, transforming the flower buds. 
North Greenbush and New Scotland. May and June. 
These fungus galls are usually from one to two inches in diame- 
ter and appear cotemporaneously with the blossoms of the shrub 
they inhabit. They are known in some localities by the name 
“May apples” and not being unpleasant to the taste they are 
sometimes eaten by voracious school boys. Upon attaining their 
full size they soon become dusted by the white spores which are 
borne upon the apices of minute filaments projecting slightly from 
the whole surface of the gall.
