A LIST OF THE MOSSES, LIVERWORTS AND 

 LICHENS OF ILLINOIS. 



By JOHN WOLF and ELIHU HALL. 



The specimens upon which the following list is based were nearly all 

 collected by the writers : those from Menard county by Mr. Hall, those 

 from Fulton county by Mr. Wolf. Those from Southern Illinois were 

 mostly obtained by Mr. Wolf, as botanical collector of a party from the 

 State Laboratory which visited the counties of Union, Johnson and Jack- 

 son, during July and August, 1877. 



We are under great obligation to Prof. Leo Lesquereux, Thomas P. 

 James, Esq., Coe F. Austin, Esq., and Henry Willey, Esq., for the de- 

 termination of species, and for many other favors.
