Beech trunks; Covington. The apothecia at length very protuberant. I 



have several fragments of the same, or a nearly allied species, collected in New 

 Mexico by Mr. Fendtler. 



' A small and delicate state, commonly granulate or squamulose, and 

 apparently distinguished by the paleness of its symphycarpaBOus apothecia. It 

 seems to be most common on M^ood, but occurs also, elsevi^here, on the earth. 



^ I have no European specimens of B. carneola (from which Fries considers 

 this scarcely to diifer) except the minute state which is the Lecidea cornea of 

 Borrer. The limits of the American lichen do not seem to be clearly ascertained. 



3 The cited brief diagnosis is all I have seen. The lichen is near to B. mixta, 

 and, although strikingly distinguished by its white bloom, appears also to be 

 approached by some states of the last species. 



4 The specimens scanty, but near to this species, which occurs about Boston, 

 and has been sent to me from N. Carolina by Mr. Curtis.
