Ascutney; in New York it is reported from Panther Mt., Catskills (Harris), 
and Mt. Whiteface, babessiare (Peck); and some of the paiecil distributed 
from Grandfather Mt., N.C., by Miss Cummincs (Decades N. Amer. Lich. 
No. 2) is referable here. It undoubtedly occurs on Mt. Katadin, Me., and I 
have seen specimens from Ontario, Canada. The plants from the eastern 
United States are nearly always sterile or show rarely minute apothecia, 
entirely smooth and more “thyrsoid-entangled,” and may possibly be worth 
Tecognition under the var. Cladonia® of TuCKERMAN, though they are in 
reality probably only reduced conditions of the more alpine fertile plant. In 
the Rocky Mountains I have seen specimens from alpine ge ae tencoing 
10,200 feet, extending from Colorado (Lake Moraine, Pikes ; Pagosa 
Peak, Veta Pass), New Mexico (Socorro Co., Mt. Gray), poten Texas 
(Parry), southern California to Mexico (Coshuia, Monterey, San Luis Potosi, 
Mt. Orizaba). 
OBsERvATiIoNS: This plant in its fruited condition, as already noted, 
strongly suggests morphologically the var. vittata Ach..of Parmelia physodes. 
t is also interesting to note that TuCKERMAN* first considered the examples 
Teferable to his Cladonia nearest to ACHARIUS’ ceratea.
