 ern Alabama and of the upper part of the Maritime Pine belt in the 

 southern section of the State have become well known. These enthu- 

 siastic explorers of its cryptogamic flora communicated the results of 

 their field work to Professor Tuckerman. In the Genera Lichenum 

 (1872) and in the Synopsis Lichenum (1882), this author credited 223 

 species and 2 varieties to the above collectors. Fully one-half of this 

 number are contained in the collection of Ifchens made by the Honor- 

 able Judge Peters, which he presented to the University of Alabama. 

 The lichens collected by the writer in Mobile aud Baldwin counties 

 (early in the seventies) have been identified by Mr. Henry Willey of 

 New Bedford and Miss Maria Wilson, and the collections made in later 

 years in the different parts of the State have been examined by Miss 

 Clara E. Cummings of Wellesley College, who has also kindly under- 

 taken the revision of the catalogue of Alabama lichens, for which 

 assistance the writer expresses here his thanks. Lately an interesting 

 contribution to our knowledge of Alabama lichens has been made by 

 the biological survey of Alabama, consisting of 74 species, mostly from
