NEW SPECIES OF TEXAS FUNGI 



F. D. Heald and F. A. Wolf 



In the spring of 1909, the writers, in cooperation with the 

 Bureau of Plant Industry, of the United States Department of 

 Agriculture, began a Plant Disease Survey of the area designated 

 as the San Antonio-Austin area. This area included the terri- 

 tory within a radius of one hundred miles of San Antonio, and 

 collections were made at many points. 



Parasitic species occurring on both wild and economic plants 

 were collected, but attention was given chiefly to cultivated crops. 

 As a result of this work, forty-one new species have been de- 

 scribed and a total of two hundred and ninety-three species, 

 on one hundred and ninety-three different hosts, have been 

 recorded. They are distributed as follows : 



Species 



On tree fruits 30 



On small fruits 7 



On truck crops 33 



On cereals and field crops 13 



On forage crops and grasses 25 



On trees and shrubs 90 



On greenhouse and garden plants 27 



On wild plants 68 



The complete report of the Plant Disease Survey is being 

 published as a bulletin by the United States Department of 

 Agriculture, and will contain figures illustrating practically all 

 of the new species, descriptions of which are published here.
