"The first part of Tuokerman's synopsis of N. Amer. Lichens containing ParmeUaoei, Clado- 

 niei and Coenogoniei enumerates 46 Genera 411 species and 58 subspecies, of which after Wolt and 

 I-Iall 22 genera with 93 species are found in Illinois. Of the rest of the genera the first edition of 

 Tuokerman's Lichenes (1848) contains only 16 genera and 109 species, and of those Wolf and Hall 

 mention as occuring iu Illinois 75 species, so that 108 species so far are known from Illinois.
