which he had found, and this list was published in Britton's 

 Preliminary Catalogue of the Flora of New Jersey (2), which was 

 issued in 1881. Austin's list, which was based on determinations 

 made by Tuckerman, includes seventeen species of Cladonia, all 

 but one from the vicinity of Closter. 



Tuckerman's Synopsis of the North American Lichens (21), 

 published in 1882, definitely accredits only five species of Cla- 

 donia to New Jersey, all of which are included in Austin's list. 

 The records for four of these are based on Austin's material, 

 the record for the fifth on specimens collected by Miss Biddle- 

 come. No definite stations are mentioned. 



In 1889 Britton published his Catalogue of plants found in 

 New Jersey (3). For this work Austin's list of lichens was re- 

 vised and amplified by Eckfeldt, who recognized twenty-one 

 species of Cladonia for the state. For most of the species the 

 New Jersey distribution is given by counties, but more definite 

 stations are listed in certain cases. 



Two years before the publication of Britton's Catalogue the 

 first part Vainio's Monographia Cladoniarum universalis (22) 

 made its appearance, the second part followed in 1894, and the 

 third in 1897. The records for New Jersey in this important 

 work are quoted directly from Tuckerman's Synopsis and give 

 no additional information about stations. Vainio's monograph 

 describes the species of Cladonia for the entire world and quickly 

 became the standard authority for students of the genus. In the 

 case of certain species the author presented views which were 

 at variance with those previously held and emphasized charac- 

 ters which had hitherto been considered unimportant. It is not 

 surprising, therefore, that some of the records in Austin's and 

 Eckfeldt's lists are in need of revision. This is particularly true 

 of species which have not been subsequently found in New 

 Jersey. The writer has examined the New Jersey Cladoniae in 

 the Tuckerman Herbarium at Harvard University, in the 

 Austin collection of lichens at the New York Botanical Garden, 

 and in the Eckfeldt Herbarium at the Philadelphia Academy of 

 Natural Sciences, and has thus been able to make the necessary 

 revision in certain cases by the study of the specimens upon 

 which the records were based. There are, however, three species 

 in the Eckfeldt list of which no specimens from New Jersey 

 have been seen. These species are the following: C. cornuta (L.)
