SECOND ALPHABETICAL LIST OF THE LICHENS COL- 

 LECTED IN SEVERAL COUNTIES OF 

 NORTHERN OHIO. 



Edo Claassen. 



Since June 1912, when the first list was pubhshed in the 

 Ohio Naturahst, 23 Hchen species, not yet Ksted, have been 

 collected. The name of the counties, where the collections 

 were made, are again abbreviated as before: C stands for 

 Cuyahoga, E for Erie, G for Geauga, L for Lake, O for Ottawa, 

 S for Summit and St for Stark. 



Several of these lichens, such as Arthopyrenia macrospora, 

 Arthopyrenia quinqueseptata, Bilimbia trachona, Lecanora 

 tartarea, Lecidea myriocarpoides and Lecidea pycnocarpa, seem 

 to be quite rare. It is hoped and expected, that in coming years 

 some more species can be added, mainly by excursions to 

 localities not as easily accessible as those which usually have been 

 visited, for instance the islands of Lake Erie.
