Fr., listed from Bergen and Warren Counties; C. rangiferina 

 var. alpestris, now C. alpestris (L.) Rabenh., listed from the 

 Pine Barrens; and C. leporina Fr., listed from Atco, Camden 

 County. For the present, therefore, the occurrence of these 

 three species in New Jersey must be considered doubtful. 



For about forty years after the appearance of Britton's Cata- 

 logue the Cladoniae of New Jersey received but little attention. 

 Collections, to be sure, were made from time to time by various 

 botanists; but little, if anything, was published about these col- 

 lections. In the last few years, however, interest in the Cladoniae 

 of North America has been revived, and several papers dealing 

 with the species of New Jersey have made their appearance. 

 The most important of these is a report by Torrey on the Cla- 

 doniae in the range of the Torrey Botanical Club (18). In this re- 

 port nineteen species are recorded from New Jersey, and 

 definite stations are given for several of these species. Another 

 interesting paper is by Lutz, who includes a list of thirteen spe- 

 cies of Cladonia in his report on |the Ecological relations in the 

 Pitch Pine Plains of southern New Jersey (8). Other papers 

 will be referred to in connection with the records for individual 

 species. 



In addition to Torrey's report, which contains descriptions, 

 keys, and illustrations, several other papers have recently ap- 

 peared on the Cladoniae of the eastern United States. These 

 include a paper on C. Beaumontii by Robbins (10), a paper on 

 C. lepidota by the same author (11), a report by the writer on 

 the Cladoniae of Connecticut (4), two supplements to this report 

 (5,6), and an illustrated paper by Robbins and Blake on Cla- 

 donia in the District of Columbia and vicinity (12). Although most 

 of these papers include no direct references to specimens of 

 Cladonia from New Jersey, they treat numerous species and 

 forms that are represented in the flora of the state. They are 

 therefore included in the bibliography at the close of the present 

 report. 



The species in the following list are arranged according to 

 the classification of Vainio (see 22), which has been adopted by 

 most of the recent writers on Cladonia. The stations for the 

 various species and forms are listed alphabetically, first by 

 counties and then by localities under the counties, and will give 

 some idea of the extent to which exploration for Cladoniae
