cedar swamps. Burlington: East Plains (Lutz, 1932, see 8, p. 

 13) and West Plains (Lutz, 1932; Evans, 1932; Miss Fulford, 

 1932). Camden: Atco {Green, 1882, N. Y., P., perhaps the ma- 

 terial upon which Fink's New Jersey record for C. verticillata 

 is based, see 7, p. 87). Ocean: near Barnegat (E. C. and G. M. 

 Leonard, 1928), Double Trouble (1932), Lakehurst (Torrey, 

 1934),Laurelton (Torrey, 1934), Seaside Park (1932), and near 

 Whiting's (Torrey, 1933). Several of these determinations were 

 made or verified by Sandstede. Torrey has recently reported C. 

 calycantha from the Pine Barrens (18, p. 128). 



The present species was named in manuscript by Delise and 

 listed without description by Nylander in 1855, as noted above. 

 This record was based on specimens collected by W. Lechler in 

 Peru. In the other two citations the species is again listed and 

 is accompanied by very brief comments, hardly sufficient to 

 constitute adequate publication. Vainio, however, gives a de- 

 tailed description of the species (22 2 , p. 199), together with a 

 long list of stations from Asia, North America, and South 

 America. His most northern station is Miquelon Island, where 

 the plant was found by Delamare; and specimens from this lo- 

 cality were distributed by Arnold (Lich. Exsic. 1149) under the 

 name "Cladonia cervicornis verticillata Hoff." Vainio gives no 

 other North American stations for C. calycantha north of 

 Mexico and the West Indies, but the species has since been re- 

 corded from Florida (see Sandstede 13, p. 57), as well as from 

 New Jersey. 



The podetia of C. calycantha agree with those of C. verticil- 

 lata in being cup-forming and in proliferating from the centers 

 of the cups. In distinguishing the. species from its immediate 

 allies Nylander emphasized the presence of scattered white 

 spots in the cortex, similar to those found in C. degenerans 

 (Floerke) Spreng., but Vainio states that such spots are incon- 

 stant. The differential characters drawn from the cups are ap- 

 parently more satisfactory. In typical C. verticillata these expand 

 more gradually than the cups of C. calycantha, they are somewhat 

 thicker at the margins, and the latter are subentire or shortly 

 dentate from the presence of sessile apothecia or spermagonia. 

 In C. calycantha the margins of the cups are more definitely 

 dentate or even irregularly incised from the presence of stipi- 

 tate apothecia.
