XXXI. A PRELIMINARY LIST OF MINNESOTA 

 XYLARIACE^:. 



F. K. BUTTERS. 



During the past fifteen years numerous collections of Min- 

 nesota fungi have been made by E. W. D. Holway, Esq., Dr. 

 A. P. 'Anderson, Messrs. E. P. Sheldon, E. M. Freeman and 

 others. The list given below comprises records of all the 

 Xylariacese which have been collected within the State and 

 deposited in the herbarium of the University of Minnesota. In 

 each case the county in which the collection was made is cited, 

 with the date of collection, and such other information as is 

 deemed of special value. A list of the fungi collected by 

 Holway was included in Professor J. C. Arthur's report on 

 botanical work in Minnesota for the year 1886,* but they are 

 included in the present list for the sake of completeness. Some 

 of Mr. Sheldon's specimens as well as the fungi included in 

 Professor Arthur's list have been previously determined, but in 

 all cases the fungi reported in the following list have been ex- 

 amined personally by the author and he takes the sole respon- 

 sibility for their correct determination. In cases where the 

 determinations as given in Arthur's list have been altered the 

 name as it appears in that list has been inserted in parentheses 

 after the citation of the collection. 



In all cases in which the nomenclature employed departs 

 from that found in Ellis and Everhart's North American Py- 

 renomycetes, the name employed in that work is inserted as a 

 synonym. 



It is to be noted that the specimens distributed by Ellis f as 

 Hypoxylon rubiginosum (Pers.) Fr. are certainly of a different 

 species from those distributed by de Thiimen \ and other Euro-
