The Ustilaginales of Indiana.' 



H. S. Jackson — Purdue University. 



The following list of the Ustilaginales or "smuts" of Indiana is 

 based primarily on the material in the writer's herbarium and in that 

 of the Purdue University Agricultural Experiment Station. All of the 

 Indiana material in the herbarium of the New York Botanical Garden 

 has also been included, most of the specimens deposited there being col- 

 lections made in Indiana by Dr. L. M. Underwood during the period 

 when he was connected with DePauw University. The only previous 

 lists of the smuts of Indiana were included in the List of Cryptogams 

 prepared by Dr. Underwood, which appeared in the Proceedings of the 

 Indiana Academy for 1893, and in the Supplementary list of 1894. A 

 total of sixteen species were recorded. A few other scattered records 

 appear in the literature, several having been made in the various lists 

 of the Fungi of Indiana, by Prof. J. M. VanHook, which have been 

 published in the Proceedings at various times. No attempt has been 

 made to include all the localities recorded for the more common species. 

 In general only those specimens are listed which the writer has had an 

 opportunity to examine. Several species are included, however, which 

 are based on the distribution records in the monograph of the Ustilag- 

 inales by Dr. G. P. Clinton, published in the North American Flora 

 Vol. 7, pt. 1, 1906. 



The present list includes a total of forty-seven species en as many 

 hosts. A large number of other species undoubtedly occur in our range. 

 The writer would greatly appreciate it if collectors would furnish dupli- 

 cates of specimens not recorded here, or which they may collect in the 

 future, for use in preparing a supplementary list. 



Acknowledgment is gratefully made to all those who have fur- 

 nished specimens for study or who have assisted in any way in the 

 preparation of the list.
