 C.es. Naturf. Freunde Mag. 2: 214. 1818. 0< ban: Seaside Park 

 (1932, det. Sandstede); apparently the rirsl record for North 

 America. The primary squamules of f. tomentosula are well de- 

 veloped, and the podetia are much like those of f. styracella, 

 except that they are more robust and more densely sorediose. 

 They are, in other words, simple or shortly and sparingly 

 branched in the upper part, and the podetial surface is free (or 

 nearly so) from squamules. European writers tend to subordi- 

 nate f. tomentosula to f. styracella, giving the latter varietal 

 rank. 



9. Cladonia DIDYMA (Fee) Yainio (5, p. 125; 18, pi. l,f. 8). 

 On decaying wood and on soil rich in humus. Torrey reports 

 the species from the "Pine Barren swamps" and also from the 

 Wawayanda cedar swamp (16, p. 167; 18, p. 122). Ocean: 

 near Forked River (Dillman, 1933); this specimen is indefinite 

 as to form, but the other New Jersey specimens seen by the 

 writer are referable to the following forms: — 



9a.* Cladonia didyma f. muscigena (Eschw.) Yainio, Acta 

 Soc. F. et Fl. Fennica 4: 141. 1887 (as a. muscigena) . C. musci- 

 gena Eschw. in Martius, Fl. Brasil. I 1 : 262. 1833. Ocean: Dou- 

 ble Trouble (1932, det. Sandstede). Sussex: Wawayanda cedar 

 swamp (Torrey, 1933, det. Sandstede). This form represents the 

 more typical development of the species and is the form usually 

 found in tropical and subtropical regions. It is larger than the 

 following and often produces apothecia. 



9b.* Cladonia didyma f. subulata Sandst. (5, p. 127). 

 Burlington : Speedwell (1932). Ocean: Double Trouble (1932), 

 Seaside Park (1932), and near Whitings (Torrey, 1933). The 

 podetia of this form are more slender than those of f. muscigena 

 and are usually sterile.
