vary all the way from a white to a black, but what we will call sea-green is 
the most common color. This color is a greenish-gray. Some other colors are 
ashy, olivaceous, brown, straw-color and various intermediate conditions 
as brownish-black and olive-brown, etc. And the thallus is often more or 
less variegated, while the lower surface is frequently of a different color from 
the upper. Also, in the fruticose forms the basal portion is frequently of a 
different color than the distal portions, usually darker. The tendency of 
thalli, as other lichen structures, is to darken with age, and the variations in 
a species may usually be traced to peculiar conditions of growth, through no 
very definite studies of this matter have been made. Grinnell, Iowa.

NOTE TO MEMBERS. 
It has been a great regret to me that my illness and long convalescence 
has prevented me from determining lichens for the members of the Sullivant 
Moss Chapter. As I do not expect for another year to be able to do this 
work, Mr. Merrill has kindly consented, not only to determine Cladonias 
for Chapter Members, but any lichens sent to him, “providing ample speci- 
mens with full data are sent.” 
Mr. Merrill’s address is G. K. Merrill, 564 Main street, Rockland, Maine. 
The interest in the study of the Lichens seems to be increasing, and 
with the help given by the excellent articles published in The Bryologist, 
the students ought to increase in number as well as in knowledge of these 
very interesting plants. 
With grateful acknowledgement of the many kind messages sent me by 
the Chapter Members during my illness, I am, cordially, 
Carolyn W. Harris.
