1922] Taylor,—Notes on some Algae 105 
APHANOTHECE SAXICOLA Naeg. Selkirk Mountains: wet rocks by 
a spring near Cascade Summit, Glacier, at 5500 feet; pools at the 
source of Quartz Creek at 6500 feet and pools east of the valley at 
6700 feet. 
CALOTHRIX PARIETINA (Naeg.) Thuret. Frequent, though never 
in any large quantity. Eagle Pass Mountains: cliffs at the Falls of 
Jordan Creek at 2000 feet, and in rivulet at 6000 feet. Selkirk Moun- 
tains: wet rocks above the head of Fish Lake at 5200 feet, rivulets 
tributary to Quartz Creek at 3000 feet and at 5700 feet, also in pools 
in pass at head of Quartz Creek at 6500 feet. 
CHROOCOCCUS COHAERENS (Bréb.) Naeg. Selkirk Mountains: in 
debris in the bottom of pools and on dripping rocks above the head 
of Fish Lake at 5200 feet, frequent. 
CuRoococcus MACROCCUS (Kuetz.) Rabenh. Selkirk Mountains: 
occasional, pools above the head of Fish Lake at 5200 feet and in the 
pass at the source of Quartz Creek, 6500 feet. 
CHROOCOCCUS MINUTUS (Kuetz.) Naeg. Frequent among other algae. 
Eagle Pass Mountains: ponds and slow rivulets at 6000 feet. Selkirk 
Mountains: on rocks near Cascade Summit, Glacier, at 5500 feet; 
pools above the head of Fish Lake at 5200 feet, and in Quartz Creek 
valley at 5700 feet, at the source of the stream at 5700 feet and in 
pools east of the valley at 6700 feet. 
CHRoococcus TURGIDUS (Kuetz. Naeg. Frequent among other 
algae. Eagle Pass Mountains: rocks at the mouth of Canon Creek 
and the cliffs at the Falls of Jordan Creek, 2000 feet; rocks between 
Jordan Creek and the Big Eddy of the Columbia River, 1800 feet. 
Selkirk Mountains: Cascade Summit Trail at 5500 feet on rocks and 
in moss, and in the valley below the Asulkan glacier among filamentous 
algae at 5000 feet. In the Quartz Creek valley it appeared from 5700 
to 6500 feet and in ponds east of the valley at 6700 feet. 
CYLINDROSPERMUM MAJUS Kuetz. - Eagle Pass Mountains: on damp 
moss in a rivulet near the Big Eddy of the Columbia River. 
DicuoTHRIX. Two algae, quite different but seeming to belong to 
this genus, were found, but could not be certainly identified with any 
known species. Rare, one in the Eagle Pass Mountains at 6000 feet and 
the other in the Selkirk Mountains at 6500 feet. 
GLOEOCAPSA AERUGINOSA (Carm.) Kuetz. Eagle Pass Mountains: 
wet rocks between Jordan Creek and the Big Eddy of the Columbia 
River, 1800 feet; cliffs at the falls of Jordan Creek, 2000 feet. Selkirk 
Mountains: wet rocks on Cascade Summit trail at 5500 feet, Glacier, 
and wet rocks above the head of Fish Lake at 5200 feet, where it was 
one of the chief items. 
GLoEOCAPSA MAGMA (Breb.) Kuetz. Selkirk Mountains: locally 
abundant, forming with G. aeruginosa and Gloeocapsa sp.? a dark red 
coating on wet rocks above the head of Fish Lake at 5200 feet.
