south it is usually very common. It is found in South. Carolina 
(Ravenel, Fungi Carol. no. 85), Georgia, Alabama, Mississippi, and is 
also reported from Florida (Wedéer) and Texas (/ennings). An inter- 
esting feature of its development occurred during the present season 
in Alabama, showing the effect of the season on habit of growth. An 
early rain caused the germination of some of the teleutospores, so that 
there was an early crop of rcestelias produced on the apples. At the 
time of the next rain, and after an interval of about six weeks, the 
remainder of the teleutospores were brought to germination, and at 
the same time the effects of the earlier sowing had already produced 
the characteristic spots and yellow thickenings of the rcestelias and 
the spermagonial stage was reached. Toward the end of July the new 
galls for the next season had already developed and had attained con- 
siderable size. With all our knowledge of this common species, we 
are still uncertain as to what may be the ordinary time and method of 
the formation of this gall on Juniperus. 
Gymnosporangium clavipes, next to G. macropus, is the most col 
mon species in central Alabama. Since it produces no enlarged gall, 
its presence is often overlooked until after the germination of its tele 
tospores, when its semi-dried gelatinous spore masses render it quil€ 
conspicuous. Its Roestelia is found on the cultivated quince and 0m 
various species of Crategus. Its range appears to be confined to the 
Appalachian region. In the south it occurs in South Carolina (Rave- 
vel, Fungi Amer. nos. 272, 502), Georgia, Alabama, and Mississipp! 
An undescribed species of Gymnosporangium is the next most 
common in Alabama, and appears also to be frequent in Mississippi 
Starkville (Tracy) and Ocean Springs (Zar/e). It is apparently ¢ 
annual species producing galls similar to those of G. macropus, but © 
a peculiar red brown color and luster, reminding one of G. Bae 
num. In shape they approximate those of G. globosum, and are often 
very small, with single spore masses, but frequently have a peculiat 
tirely 
devoid of the characteristic bark colored flakes of G. globosum. 
Spore masses are darker, shorter, broader and more conical than © 
of G. macropus, and are wholly unlike the dark wedge shaped mass 
of G. globosum. The spore characters are also different from either . 
the two allied species. The rcestelia of this interesting species ne
