Peltigerei. 



Nephromium lusitanicum, ScJmr. 



On stunted bushes near the sea ; very rare. 



On stunted blackthorns on Lydd Beach. 



This Hchen grows in exactly the same way on the sandhills 

 near Winchelsea in Sussex, in which county Dillenius first dis- 

 covered it. 



It is easily distinguished from the other British species by the 

 yellow medulla, which turns red when touched with potash.

not common. E. B. t. 2300. 

 Between Lamberhurst and Goudhurst ; Jenner Fl. Tunbr. Near 



Eusthall Common ; Thornden Wood, near Canterbury. 

 The locality from Jenner Fl. T. is placed here with hesitation, 

 for although the two towns are both in Kent, a considerable 

 portion of the main road between them is in Sussex.
