LICHENS OF LICKING COUNTY, OHIO. 



J. Orrin R. Fisher, M.S. 



The following list is intended to include such lichens as have been 

 found in this county, and worked up by the author during the school 

 year of 1893-94 in the Denison University laboratories. To this list 

 have been added a {e\v specimens from the neighboring county of 

 Muskingum; the localities given being followed by " L." for the for- 

 mer, and by " M." for the latter county. 



The names and authorities are given in conformity with Tucker- 

 man's " Synopsis of the North American Lichens," and most of the 

 identifications have been confirmed by other investigators. 



In this list are at least four specimens not before reported for the 

 State, viz : 



Cladonia symphycarpa Fr.; 



Lecanora cenisia Ach.; 



Pannaria nigra (Huds.) Nyl.; 



Peltigera canina (L.) Hoffm., var. spongiosa Tuckerm. 



As to collecting it is difficult to say where are the best localities, 

 for all are good ; but a trip to Black Hand for crustaceous and rock 

 lichens, to Buckeye Lake or Munson's Hill for fruticulose lichens, 

 and to the region around Newark or to Pleasant Valley for foliaceous 

 ones, will reward the collector with many fine specimens. 



The study of lichens is an interesting one, and offers to the dili- 

 gent and careful student a rare field for investigation from the fact 

 that there are many points yet to be determined in their structure, and 

 very many speciniens yet to be classified and named. 



The following lines quoted by Henry Willeyinhis " Introduction 

 to the Study of Lichens," represents the attractiveness of the study : 

 " If I could put my woods in song. 

 And tell what's there enjoyed. 

 All men would to my garden throng. 

 And leave the cities void.
