12. Buxbaumia aphylla L. Barrasois 1820. 
13. Polytrichum piliferum Schreb. Wreck Cove 1816. Recorded also 
from Nova Scotia (Macoun). 
These additions bring the number of species of bryophytes recorded as 
having been collected in Cape Breton up to 361: 96 liverworts and 265 mosses. 
The bryophyte flora of the province of Nova Scotia as a whole is now known 
to include 408 species: 105 liverworts and 303 mosses. The writer is indebted 
to Dr. A. W. Evans, Dr. A. L. Andrews, and Mrs. E. G. Britton for assistance 
in determining various species.

LICHENS OF THE BERKSHIRE HILLS, MASSACHUSETTS 
Stewart H. Burnham 
Two lists of lichens are enumerated below. Bash Bish Falls in the south- 
western part of Berkshire county, near Copake Iron Works, N. Y., was visited 
the afternoons of Aug. 1, 1908, and July 3, 1909. No special attention was 
given to collecting lichens; however, this wild rocky gorge supports rather a 
rich lichen flora as well as many fine mosses. 
Mt. Greylock, in northern Berkshire county, was visited on the following 
dates: July 4-5, 1908; May 29-31, and Oct. 9-10, 1909; and May 28-30, 1910. 
It is the highest land in the state of Massachusetts, 3505 feet above the level 
of the sea. The open rocky summit is fringed with forests of balsam fir, Abies 
balsamea (L.) Mill.; yellow birch, Betula lutea Mx. f. ; and small trees of moun- 
tain ash, Sorbus americana Marsh. The trunks of these trees, old decaying 
wood, and the earth in sheltered situations, is the habitat of a rich and notice- 
able lichen flora. 
A few of the lichens have been determined by Dr. L. W. Riddle, of Wellesley 
College, and some by Mr. G. K. Merrill, of Rockland, Maine.
