Sticta anthraspis Acharius, Meth. Lich. 280. 1803. 
Point Gustavus, Glacier Bay (Coville and Kearney, 775). New to 
Alaska. 
Plant well developed, but sterile. Acharius founded the species on 
material collected on the coast of California by Menzies. Tuckerman 
records it as found in Oregon by Hall. Macoun’s Canadian Lich. no. 
153 was collected at Victoria. 
155. Sticta crocata (L.) Ach. 
Lichen crocahis Linn/eus, Mant. 310. 1771.

Yakutat (Trelease, 1100 in part). Sterile specimen on dead conif¬ 
erous twigs with Nephroma Icevigatum and Physcia tribacea. New 
to Alaska. 
This is a widely distributed lichen. Arnold records it from New¬ 
foundland, J. M. Macoun from Canada. It is not mentioned in Fries’ 
Lich. Arct., and the Yakutat station would seem to be the most north¬ 
ern one established on this continent.
