Lizhenes of New England. 955. 
British plant, nor: to § 4 cherer’s specimen of the Swiss. 
The latter is hoe "vu. Acharius called his var. 7, 
flocculósa, and perhaps Hooker has incorporated the 
variety into his description, as he does not notice it 
apart. Our plant is certainly distinct from G. probosci- 
dea; but I am not sure uee it will prove -to belong to 
. G. deüsta.

Bear Hill, Waltham ; Mt. Ascutney, Vt.; White Moun- 
tains (in the Notch). This appears to be the most common 
of our New England species. It is also, so far as my 
knowledge extends, the largest and most coriaceous form 
of the genus. ` It seems to vary in the color of the upper 
surface ; some plants being olive-brown of different de- 
grees, and glabrous, and others of a very light ash- 
color, and pulverulent. These differences are some- 
: times strongly. marked, but I have not noticed any 
other. Plants i in the state of fructification seem to be 
rare, but I found them abundantly at the White Moun- 
tain station.
