is no specimen in hb. Dill., who copies simply the fig. of Michaeli, 



which Acharius, in Meth. p. 302, refers to (Cornicularia) Getraria 

 aculeata. 



Subdivision II. Species with the leaves closely adnascent, and 



the scutellse unicolorous or bicolorous. 



F. 68. Lichenoides tenuissimum, scutellis exiguis miniatis, 

 p. 175, = Lecanora elegans {Link) (minor). There is no spe- 

 cimen present ; but there can be little doubt that authors have 

 rightly referred it to this species. 



F. 69. Lichenoides angustifolium fuscum, scutellis pullis, p. 175, 



Physcta aqtjila (Ach.). Of this there are two typical and 

 fertile specimens. 



P. 70. Lichenoides cinereum, segmentis argutis stellatis, scutellis 

 nigris, p. 176. A, B = P. atpolta f. acrita, Ach. Fertile. Rightly 

 determined by Acharius in L. XT. p. 478. C = P. c^sia (Hffm.). 

 Fragmentary and sterile. Not sufficiently distinguished from the 

 preceding by authors. 



P. 71. Lichenoides glaucum orbiculare, segmentis latiusculis, 

 scutellis nigris, p. 177. A. There are two small specimens of this, 

 of which one = Physcia pulyerulexta (Schreb.), and the other 



P. stellaris (L.). B = P. pttlverttlenta f. argyph^a, Ach. 

 C = P. pityrea (Ach.). Infertile. Along with this is also a ste- 

 rile fragment of P. speciosa (Wulf.) from Virginia. D = P. pttl- 

 yertjlenta f. pannieormis, Cromb. Sparingly fertile. "With 

 the exception of A pro p. (P. pulverulenta), the others have not 

 hitherto been determined. 



P. 72. Lichenoides viride, segmentis angustis distortis, scu- 



tellis pullis, p. 178, A = Physcia tjlotiirix (Ach.). Fertile. 

 B = P. obscura, var. yirella, Ach. The specimens of both are 

 fragmentary, much worn, and with difficulty determinable. This 

 latter has not been distinguished by lichenists. 



Subdivision III. Leaves closely adnascent, moderately broad 



(except n. 81). 



P. 73. Lichenoides tenue et molle, Agarici facie, p. 179, = Coc- 

 cocarpia plumbea (Lghft.) The specimen figured, though frag- 

 mentary, is sufficiently typical and fertile. Along with it are 

 two specimens of Pannaria rubiginosa (Thnb.), which were pro- 

 bably added at a later period. 



F. 74. Lichenoides cartilagineum, scutellis fulvis planis, p. 179,
