Lichenes of New England. 303 
Beside this, I have found two other forms, which, 
though differing considerably in some respects from 
the typical form of C. gracilis, an examination of 
Schærer’s series of this species has led me to unite 
with it. The first of these may be called, — var. 
grandis: podetiis grandioribus fuscis sæpe squamo- 
sis; cephalodiis magnis nigro-fuscis. — In the alpine 
regions of the White Mountains ; aud in similar situ- 
ations on the Chin of Mansfield, Vt. A conspicuous 
and abundant alpine lichen, quite different in appear- 
ance fromthe ordinary C. gracilis, but probably one 
of the various forms of that species. The other 
plant above mentioned, I have less difficulty in refer- 
ring to one of the varieties indicated by Scherer. It. 
appears to be the var. 7. macroceras, B. elongata, 
Scher., identical. with Cenomyce ecmocyna, 7. ma- 
croceras, B. elongata, of Ach. The character is inti- 
mated by the names, and consists in the length and 
size of the podetia ; and especially in the elongation 
and furcation of the branches of the scyphiform ex- 
tremities. .'l'his occurred on the White Mountains, 
with the last, barren. |
