ADDITIONS TO LICHEN DISTRIBUTION IN 

 NORTH AMERICA 



Bruce Fink 



Some of the material which has been accumulating in my her- 

 barium for many years has not been published. By far the 

 greater portion of this is mainly of interest to those for whom 

 the determining was done, but somewhat more than 200 species 

 are worth recording as additions to distribution. 



Many of the species recorded in this paper were collected by 

 the writer, on the islands of Puget Sound, during a sojourn of 

 six weeks at the Seaside Station of the University of Washington, 

 in the summer of 1906, with headquarters at Friday Harbor, on 

 San Juan Island. On the return trip, a week was spent at Glacier, 

 British Columbia, and Laggan, Alberta. At these two places high 

 elevations were reached, and much interesting material was se- 

 cured, part of which is recorded in this paper. Little has been 

 recorded definitely for any of these places in way of lichen dis- 

 tribution, though the areas are covered in a general way, for many 

 of the species, in Tuckerman's Synopsis. 



For several years the writer determined lichens collected by L. 

 H. Pammel in the western mountains. Colton Russell sent spec- 

 imens from Missouri and other western states many years ago. 

 T. C. Frye sent a considerable number from the Olympic Moun- 

 tains in Washington, and E. T. Harper has added to the list by 

 collections from several areas. Several other botanists and zool- 

 ogists have added somewhat to the list published herein. 



The list follows, given for distribution, and divested of all 

 other non-essential data. Where no collector is named, the col- 

 lecting was done by the writer. 



Acarospora cervina (Wahl.) Koerb. 



Waldron Island in Puget Sound, 1906, rocks. 

 Acarospora chlorophana (Wahl.) Ach.

 British Columbia, 1906, rocks.
