Tribe 4. Ramaline^e. 

 Ramalinece et Cctrariece, Nyl. Syn. 277 et 297. 



The species of the vast genus Ramalina approach so clearly on the one 

 hand Cornicularia, and Cetraria on the other in their vegetative characters (the 

 bilocular spores are not a tribal character), that Ramalinese and Cetrariese 

 of Nylander, notwithstanding the usual difference in the spermogones, must be 

 united in one tribe.

Omnino eadem est ac R. tenclla, Mull. Arg. (L. B. n. 97), et nomen R. dendriscoides, Nyl. 

 prioritate gaudet ; etiam in speciminibus cubanis, C. Wright (Lich. Cub. ser. ii. n. 738),
