THE BED FUNGUS. 25 
Orlando, on the underside of sweet potato leaves, that several bushels 
of leaves of this plant were picked as the easiest way of procuring a 
supply of fungus for experimental purposes. Mr. W. C. Temple, of 
Winter Park, also noted a similar attack upon a sweet potato aley- 
rodid, probably the species above mentioned, in July, 1909. The 
senior author has several times seen pustules on Aleyrodes jloridensis 
Quaint ance on guava at Orlando and Manatee, and on another, as 
yet undetermined, aleyrodid attacking Spanish mulberry at Orlando, 
while in 1908 Messrs. M. T. Cook and W. T. Home reported it 
attacking A. Jiowardi Quaintance as well as A. citri in Cuba. 1 The 
junior author has found a rank growth of this fungus on a white fly 
(Aleyrodes abutilonea Hald.) at Orlando. 
DISTRIBUTION. 
In Florida the red Aschersonia occurs in all the leading orange- 
growing sections infested with the citrus white fly. The fact that 
Dr. Webber reported it from such widely separated places as Gaines- 
ville, Bartow, and Fort Myers, is sufficient evidence to warrant the 
conclusion that even then its distribution was wider than known. 
It is being continually reported from or introduced into new localities, 
and at present may be said to occur in greater or less abundance in 
Florida in all sections infested by the citrus white fly. It is most 
widely distributed in Manatee, Lee, and Orange Counties. 
Outside of Florida the red Aschersonia now occurs in different 
points in Louisiana, having been introduced by agents of the Louisiana 
Crop Pest Commission. In 1905 Mr. F. S. Earle 2 reported this 
fungus on A. citri in Cuba. In 1906 Mr. J. Parkin 3 mentioned 
finding in Ceylon an Aschersonia closely resembling aleyrodis on 
several undetermined species of Aleyrodes. Dr. Berger has identified 
this species of fungus on citrus leaves infested with Aleyrodes citri 
from Japan, 4 and the junior author found it attacking A. Jiowardi in 
1910 in both Cuba and Mexico. 
HYPERPARASITIC FUNGI. 
Thus far the red Aschersonia has not been subjected to wide- 
spread attack by hyperparasitic fungi. In sheltered places during 
the late summer and in the fall the pustules sometimes become over- 
grown by the species of Cladosporium mentioned more fully under 
the hyperparasitic fungi of the yellow Aschersonia. In a grove at 
Mcintosh, Fla., examined in December, 1907, it was estimated that 
fully 50 per cent of the red-fungus pustules were overgrown by this 
hyperparasite. Old worn-out pustules are often entirely overrun late
