Cladoniae in the range of the Torrey Botanical Club 



Raymond H. Torrey 



This is an attempt to list and describe the species of the 

 interesting and often beautiful lichen genus, Cladonia, which 

 have been found or which may be looked for, in the range of the 

 Torrey Botanical Club, covering New Jersey, eastern Penn- 

 sylvania, Long Island, and the Hudson Valley in New York as 

 far north as the northern Catskills. 



This treatment of the subject is offered for beginners, who, 

 like the writer, have become interested in lichens, and for whom 

 there is yet little available in the way of popular guides such as 

 exist for flowering plants, ferns and mosses. This lack of guides 

 has prevented inclusion of lichens in the usual forms of outdoor 

 nature study. Study of lichens seems to have lagged behind that 

 of other plants in the United States, and the number of special- 

 ists in lichens is small. 



Recent appearance, in scientific journals, of more accessible 

 literature, has stimulated interest in lichens, and it is to be 

 hoped that before long, some well-illustrated guidebook, simi- 

 lar, for example, to Dr. A. J. Grout's "Mosses with a Hand 

 Lens," will appear. Mrs. Gladys P. Anderson, of Rahway, 

 N. J., a member of the club, has been working for years on such 

 a book, and it is hoped it may soon appear. The writer owes 

 largely to Mrs. Anderson his introduction to the study of 

 lichens, as well as unfailing aid in their identification. He also 

 owes thanks to Dr. Alexander W. Evans, of the Osborn Botani- 

 cal Laboratory, Yale University, for many kindnesses in identi- 

 fications and encouragement in this field of botany. Dr. Evans' 

 monograph on "The Cladoniae of Connecticut," is the most 

 thorough treatment of this genus for the eastern United States. 

 It was first published in the Transactions of the Connecticut 

 Academy of Sciences, in 1930, and later as a reprint, by the 

 Yale University Press. A revision of his list of species with
