IOWA DISCOMYCETES 



BY FRED J. SEAVER 



INTRODUCTION 



The work of the present paper was begun during the autumn 

 of 1902, under the direction of Professor Thomas H. Macbride, 

 in the State University of Iowa. The work was continued 

 during the four years following this period, the first three 

 of which were spent in Iowa City as a student of the University 

 and the fourth at Mt. Pleasant in charge of the biological 

 work in Iowa Wesleyan University. To Professor Macbride and 

 the various members of the botanical department of the State 

 University I am indebted not only for free access to the mate- 

 rial in the collections of that department, but for constant sug- 

 gestions and aid on the numerous questions which have arisen 

 during the course of the work. 



Having since taken up my residence in New York City access 

 to the libraries and collections of the New York Botanical Gar- 

 den has afforded the opportunity to put the manuscript of the 

 Iowa Discomycetes into better form. The library facilities of 

 this institution have made it possible to confirm the citations of 

 nearly all the species named, and to correct determinations in 

 several cases; to the authorities of this institution I wish to ac- 

 knowledge my indebtedness for the privilege of completing the 

 work begun in Iowa. 



A preliminary paper on the Discomycetes of Eastern Iowa was 

 published in the spring of 1904 1 and the present paper stands 

 in part as a revision of that work with the addition of work 

 done subsequent to the time of that publication. The present 

 work includes, not only the work of the writer but all the infor- 

 mation which he has been able to accumulate from other sources 

 on this part of the fungous flora of Iowa.
