Miss H. J. Biddlecome, at present of Columbus, Ohio, began 

 collecting them in 1874 at Cedar Swamp, near Urbana, Cham- 

 paign Count)-, and about Springfield. She continued the 

 work for the next four 3'ears. 



Mrs. E. Jane Spence collected in the same localities in 1876 

 and a few ^-ears later. Mi.ss Biddlecome and Mrs. Spence sent 

 material to Drs. Beardslee and Tuckerman for identification, 

 and each has now a collection of sixty to seventy-five species. 

 These ladies have kindly permitted the use of their lists in 

 making out this one. 



Mr. W. C. Werner, at present of the Ohio State University, 

 began collecting Lichens at Painesville in 1879, and has con- 

 tinued the work more or less since. 



The author began collecting them in November, 1S91, and 

 has improved everj- opportunity to continue the work. Since 

 June, 1892, my collecting has been for the Botanical Depart- 

 ment of the University. 



Professor W. A. Kellerman collected at several places during 

 the past season, so that now there is a good supply of material 

 at the University for use of same, and for opportunity of 

 carrying on the work in the Botanical Laboratory, I hereby 

 express my obligation. 



I take pleasure in acknowledging the kindness of Miss 

 Clara E. Cummings for identifying the more foliaceous ones. 

 Thanks are especially due to Dr. John W. Eckfeldt for deter- 

 mining the less conspicuous and more difficult species. I 

 have been favored by Mr. Fredrick LeRoy Sargent with the 

 determination of material, and with suggestions on working 

 it out. 



No less than twenty-six State and local floras are known to 

 have been published in the State, but only the two above- 

 mentioned listed any Lichens. 



It is not expected that this list of one hundred and sixty-six 

 (166) Lichens includes nearly all that can be found in the 

 State. There are probably at least one hundred yet to be 

 brought to light. It is expected that many additions will be 

 made the coming year. With the exception of those quoted 

 from Riddell and Lea, and in a very few other cases, the names 

 given are supported by specimens, nearly all of which are 

 deposited in the Herbarium of Ohio State University.
