Dr. Nylander reports its occurrence on earth and moss on St. Law- rence Island; Dr. Rothrock credits it to Alaska, with no definite station. Under the synonym S. globiferus (L.) DC., it is reported by J. M. Macoun as growing on rock on St. Paul and St. George Islands. Dr. Grace Cooley collected it at Loring, and also at Salmon Creek, near Juneau, and Dr. Bean at Port Mulgrave and on Little Koniuji Island, of the Shumagin group. It seems to be one of the most widely dis- tributed of the Alaska lichens, the material collected by the members of the Harriman Expedition being obtained on the mainland and on islands near the coast from British Columbia to Cape Nome. All the specimens are sterile excepting those from Glacier Bay and St. Michael, which are large and well fruited. Usually the southern forms are more finely divided than those from the northern stations. This species seems to be more abundant and more widely distributed than the following one. 8.
