1909] Riddle,— Some Lichens from Gaspé Peninsula. 101 
SoroRINA crocea (L.) Ach. "l'able-top Mountain, Gaspé County, 
Quebec, Aug. 10, 1906 (Collins & Fernald, no. 4502a). Widely 
distributed in British America, but not previously recorded from south 
of the St. Lawrence and no further herbarium material seen 
SPHAEROPHORUS FRAGILE Pers. ‘T'able-top Mountain, Gaspé 
County, Aug. 5, 1906 (Collins & Fernald, no. 4365). ‘This is only 
the third station known south of the St. Lawrence, the others being 
Mt. Katahdin, Maine (Blake, E. D. Merrill) and the White Mountains, 
N. H. (Tuckerman, W. С. Farlow, Clara E. Cummings). 
The two species next to be mentioned are represented in the collection 
by unusual forms. 
PLAcopIUM ELEGANS (Link) DC. var. GRANULOSA Schaer. Ac- 
cording to the description no. 4844 from Ile au Massacre, Bic, is this 
variety. No other herbarium specimens have been seen, and the 
variety has not been previously recorded from North America. It 
differs from the typical form in having the cortex of the central portion 
of the thallus broken up into a mass of pale granules. From the variety 
trachyphyllum of Tuckerman it is quite distinct in being truly foliose 
and loosely attached to the substratum. 
Puyscia CILIARIS (L.) DC. var. cuiNALIS Schaer. This is a com- 
paratively well-known British American lichen, material having been 
examined from the following localities: — Newfoundland (Delise), 
Nova Scotia, Gaspé Coast, Ontario (Macoun), Bic, Quebec (C. ©. 
Pringle), Lake Superior (C. С. Loring). lt is rare from the United 
States, material having been seen only from Vermont (C. C. Frost, 
C. E. Faxon) and Michigan (M. L. Wilson). No. 27 of Calkins's 
North American Lichens from Tennesee, bearing this name, is Physcia 
leucomela (L.) Michx. Collins & Fernald's no. 5138 from Bic is 
the characteristic form of the variety. But no. 5268 from Bonaventure 
Island, off. the easternmost point of the Peninsula, is a very peculiar 
form, being erect-fruticose, and occurring in intricately branched, 
congested tufts, giving the specimens an entirely different appearance 
from any other material examined, so different in fact that I failed 
to recognize it and I am indebted to Prof. Farlow for pointing out its 
relationships. 
The last species worthy of notice is at the same time the most puz- 
zlng. It may be called provisionally 
COLLEMA PLICATILE Schaer. since it agrees most closely with the 
only specimens bearing this name in the ‘Tuckerman Herbarium. One
