572 REV. J. M. CR0HBIE ON THE LICHENS OF 



Sqitaharia crassa, BO, Of this there are four specimens, all 

 of which are typical and fertile. 



F. 75. Lichenoides imbricatum viridans, scutellis badiis, p. 180. 

 A = Parhelia conspers a (Ehrh.). Typical and fertile. B = Par- 

 helia conspersa f. isidiata, Anzi. Fertile. Along with 

 this latter there is also a small specimen of P. centrifuga (L-)> 

 from which the preceding was not distinguished by our earlier 

 lichenists. 



P. 76. Lichenoides vulgare sinuosum foliis et scutellis luteis, 

 p. 180. A, B, C = PnYSciA parietina (L.). Fertile. (B 

 spermogoniiferous state). Along with these there are also two 

 fertile specimens of f. viridescens. 



P. 77. Lichenoides olivaceum, scutellis laevibus, p. 182. A 

 Parhelia olitacea (L.). Typical and fertile. B=P. euligi- 

 kosa (Fr.). Infertile. C.=P. subaurieera, Nyl. Sterile. The 

 last two have not hitherto been determined. 



P. 78. Lichenoides olivaceum, scutellis amplioribus verrucosis, 

 p. 184. A, B = Parhelia exasperata (Ach.), of which B is 

 fertile. In addition to the two specimens figured, there are seve- 

 ral others very fragmentary and scarcely determinable. Rightly 



referred to this species (s. n. /3 aspidota) by Acharius in Meth. 

 p. 214. 



P. 79. Lichenoides acetabulis cutaneis et rugosis, p. 185, 

 Parhelia acetabultjh (Neck.). There is no specimen in hb. 

 Dill., the one figured being taken from hb. Sherrard. 



P. 80. Lichenoides saxatile tinctorium, foliis pilosis purpureis, 

 p. 185,=Parhelia saxatilis, var. ohphalodes, Ach. There 

 are no specimens of B, C, D ; and A, of which a portion is deli- 



. ■ 



neated in the figure, is infertile. D is evidently a smaller state 

 with young apothecia. 



F. 81. Lichenoides tinctorium atrum, foliis minimis crispis, 

 p. 188, = Platysha Fahlufekse (£.). Of this there are only a 

 very few fragments in hb. Dill., upon which one or two young 

 apothecia are visible. 



F. S2. Lichenoides tinctorium glabrum, vesiculosum, p. 188, 

 Plattsha glattctth f. ampullaceuh (L.). There is no speci- 

 men present ; and as the figure is inserted in its place, as in 

 other similar instances, there seems never to have been a speci- 

 men. But vide "Withering, Arr. iv. p. 68. 



P. 83. Lichenoides vulgatissimum cinereo-glaucum, lacunosum 



et cirrosum, p. 188. A = Parhelia saxatilis (L.). Typical,
