TEXAS PARASITIC FUNGI 



New Species and Amended Descriptions 



B. C. Tharp 



The new species of pathogenic fungi described in this article 

 were among the specimens of two series of collections ; the first 

 of these having been begun in the summer of 1914 and continued 

 to the early spring of 191 5, the second beginning in May, 191 5, 

 and continuing to midsummer, 191 6. The first was undertaken 

 under the direction of Prof. I. M. Lewis, of the School of Botany, 

 University of Texas, for the purpose of obtaining material for a 

 graduate thesis, which was intended to supplement the work of 

 Heald and Wolf, as published in their Plant Disease Survey in 

 Texas (Bui. 226, Bur. PL Ind., Jan. 1912). Beside the Austin 

 vicinity, collections were made at several points in east and north- 

 east Texas. 



On May 1, 191 5, the writer began work in plant pathology for 

 the Texas Department of Agriculture, and the second series of 

 collections has been made since that time, partly by himself, both 

 alone and in company with others, and partly by members of 

 the field force of the Department. The place and date of col- 

 lection, together with name of collector, follows the description 

 of each of the following species. Unavoidably delayed verifica- 

 tions kept the first series from being fully reported in the thesis 

 above mentioned ; hence its inclusion in the present paper. 



Identifications were made and descriptions written by the 

 author, verifications of those fungi of both series belonging to the 

 order Uredinales being kindly undertaken by Professor J. C. 

 Arthur. Fungi in the first series of collections not belonging to 

 the order Uredinales were submitted to Mrs. Flora W. Patterson, 

 of the Mycological Herbarium, Washington, D. C, while the 

 writer himself visited this herbarium in September, 191 6. for the 

 purpose of verifying the new and doubtful species in the second
