some of the material. Dr. Evans has supplied notes on many 

 stations of species, from specimens in the herbarium in the 

 Osborn Botanical Laboratory, and from other records, estab- 

 lishing their occurrences more widely than was known to this 

 writer, especially <>f the extension northward of the range of 

 species reported in the paper on the "Cladoniae of the Range 

 of the Torrey Botanical Club." 



I se has been made of the authorities cited in the first paper; 

 Prof. Bruce M. Fink's "Lichens of Minnesota;" Prof. Edward 

 Tuckerman's "Synopsis of North American Lichens;" Annie 

 Lorain Smith's "Manual of British Lichens;" Dr. A. W. Evans' 

 "Cladoniae of Connecticut," and the supplement thereto in 

 the July-August, 1932 issue of Rhodora, journal of the New 

 England Botanical Society. Two additional lists of northern 

 Cladoniae, kindly called to our attention by Dr. Evans, have 

 been found very useful in checking species: "Cladoniae from 

 the Valley of the Cap Chat, Gaspe Peninsula, Quebec," by 

 A. F. Allen, in the May, 1930 issue of Rhodora; and part of 

 an article on "Lichens of the Gaspe Peninsula," in the instal- 

 ment covering the Cladoniae, in the October, 1926 issue of 

 Rhodora, by Dr. C. W. Dodge. These papers will be found very 

 useful by any students of Cladoniae who may be able to reach 

 the higher summits of the Shickshock Mountains in the interior 

 of the peninsula, which has been made more accessible in recent 

 years by the completion of the automobile highway around the 

 north shore, making the region an attractive one for summer 

 vacation botanizing tours. 



Dr. Evans has also added to the information of this writer 

 through references from a paper by Merrill, the 12th of his 

 series of Lichen notes, which appeared in the Bryologist, journal 

 of the Sullivant Moss Society, for September, 1909, entitled 

 "The Cladonia specimens of 'Lichenes Boreali-Americani.' 



Many of the species given in the key in this article are not 

 listed in the older American works on lichens, and some of them 

 are not found in any readily accessible reference works, but 

 were identified by Dr. Evans, according to names now generally 

 accepted, from the universal treatment of Cladoniae, by Profes- 

 sor Edward August Vainio, the distinguished Finnish authority, 

 of whose work there are very few copies in this country. The 

 popular treatment here offered may therefore be justified in
