Read by title, May 2, 1893. 



Also at the meeting of the Ohio Academy of Science, at 

 Columbus, December 29-30, 1S92. 



The Ohio botanists who have devoted their time and atten- 

 tion to this grotip of plants are few and far between. While 

 there has not been an Ohio man of supreme authority on the 

 group, the number of minor collectors may be as large as that 

 of any other State. 



Mr. John L- Riddell, in 1835, published a list of eight (8) 

 Lichens in the " Western Journal of the Medical and Physical 

 Sciences." Six of the number were from Ohio. They were 

 of the most common species. He worked them out as best he 

 could by the use of Acharius' work on the group. 



Leo Lesquereux collected a considerable number, but 

 never, so far as I have been able to learn, published a list. 

 His collection was sent to Switzerland. 



W. S. Sullivaut, in 1840, published a "Catalogue of the 

 Plants Found in the Vicinity of Columbus," but did not 

 include Lichens. 



Thos. G. Lea, in 1849, published a "Catalogue of the 

 Plants of Cincinnati," in which was recorded sixty-eight (68) 

 Lichens. Copies of the publication are very scarce. A com- 

 plete copy of the list and remarks has been secured for this 

 list. Nothing seems to have been done on the group during 

 the succeeding twenty-three years. 



Dr. H. C. Beardslee collected at Painesville in 1872. He 

 sent material to Austin for identification. His " Catalogue of 

 Ohio Plants" was ptiblished in 1874, but no mention was 

 made of Lichens.
