NOTES ON SOME LICHENS FROM THE GASPE 
PENINSULA. 
Lincotn WarE RIDDLE. 
‘THROUGH the courtesy of Prof. J. F. Collins I have recently had the 
opportunity of studying a set of Lichens collected by him in company 
with Prof. Fernald in the Gaspé region of eastern Quebec. The col- 
lection laid no claim to being exhaustive, as the specimens were mostly 
picked up incidentally, attention being given chiefly to other groups 
of plants. Most of the numbers as might be expected were typical 
boreal species, such as Cetraria nivalis (L.) Ach., Nephroma arcticum 
(L.) Fr., Cladonia deformis (L.) Hoffm., C. gracilis var. chordalis 
(Flke.) Schaer., and C. turgida (Ehrh.) Hoffm. But among the set 
were some species of special interest. 
The first two species are of interest on account of their geographical 
distribution in North America. Prof. Fernald has already called 
attention to the interesting discovery in the Gaspé Peninsula of species 
of Phanerogams known elsewhere only from the Rocky Mountains or 
the Pacific Coast. A similar distribution is illustrated by the following 
species of Lichens. 
BIATORA GLOBIFERA (Ach.) Fr. This species is widely distributed 
in the Pacific Coast and Rocky Mountain region, material having been 
examined from the following localities: — Washington (Brandegee), 
Oregon (Suksdorf), California (Bolander, C. R. Orcutt, W. G. Farlow, 
H. E. Hasse), Nevada (S. Watson), Colorado (Brandegee, F. E. 
Clements.) "Тһе only station hitherto known east of the Rocky 
Mountains is Smuggler's Notch, Mt. Mansfield, Vermont, where it 
was collected by C. G. Pringle. 'l'o this may now be added Bie, 
Rimouski County, Quebec, July 4, 1907 (Collins & Fernald, no. 4864). 
LECIDIA COERULEONIGRICANS (Lightf.) Schaer. (Lecidia vesicu- 
laris (Hoffm.) Ach.) ‘This is apparently a rarer species than the 
preceding. Material has been examined from Utah (S. Watson, 
J. A. Lapham), Colorado (C. G. Pringle), California (C. R. Orcutt). 
The only station known in eastern North America is Bic, Quebec, 
where it was collected by C. G. Pringle in 1880, and again in 
the same locality by Collins and Fernald (no. 4847a) July 4, 1907. 
The next two numbers are boreal species which are little known 
south of the St. Lawrence River.
