These, in the opinion of the writer, represenl C. apodocarpa and 



are included in the above list. The Blue Mountain specimens 

 are not in the Eckfeldt collection, and a later record for the 

 species from Passaic County, as shown on page 96, was based 

 on specimens of C. squamosa. Under the circumstances it does 

 not seem advisable to consider C. turgida a member of the New 

 Jersey flora.

24. CLADONIA mitrula Tuck. (4, p. 444). On earth, often 

 on sandy banks. This species was collected at Closter by Austin 

 as long ago as 1861, and the following records are based on his 

 specimens: 2, p. 164; 3, p. 372, in part; 20, p. 147; 21, p. 240; 

 and 22 2 , p. 50. Eckfeldt (3, p. 372) lists the species also from 

 Camden and Sussex Counties, and Torrey has recently noted 

 its occurrence at Andover (17, p. 50). The New Jersey speci- 

 mens studied by the writer are referable to the following 

 forms: — 



24a. Cladonia mitrula f. imbricatula (Nyl.) Vainio (4, p. 

 444; 12, pi. 211, f. 8; 18, pi. 3,f. 3). Bergen: Closter (Austin, 

 1861, 1867, F., N. Y.) and Palisades (Austin, 1876). Burling- 

 ton: near Pemberton (E. C. and G. M. Leonard, 1928). Camden: 

 Atco (Eckfeldt, 1882, P.). Ocean: New Egypt (Mr. and Mrs. 

 Taylor, 1932). Passaic: Green Pond Mountain (Dillman, 1934). 

 Union: Watchung Reservation (Torrey, 1932). Warren: Kit- 

 tatiny Mountain (Torrey, 1932). No specimens from Sussex 

 County are in the Eckfeldt collection. 



24b.* Cladonia mitrula f. pallida Robbins (4, p. 445). 

 Warren: Kittatiny Mountain (Torrey, 1933). 



The related species C. cariosa (Ach.) Spreng., which has 

 sometimes been confused with C. mitrula by North American 

 lichenists, is reported by Austin from Closter (2, p. 164) and by 

 Eckfeldt from Bergen and Camden Counties (3, p. 372). The 

 Austin collection contains a single New Jersey specimen re- 

 ferred to C. cariosa. This specimen is labeled "Palisades, 1876," 

 and, as noted above, represents C. mitrula f. imbricatula. The 

 specimens from Camden County were collected by Eckfeldt 

 himself, according to his list, but are not represented in his col- 

 lection. There is, however, a specimen from Atco, Camden
