Lecanora varia symmicta AcnxKlvs, L. U, 379. 1 8 10. 



St. Lawrence Island (Trelease, 1 156 in part). On dead wood, with 

 Parmelia saxatilis omphalodes. New to Alaska. 



Lecanora varia, with its varieties, is a widely distributed species, and 

 it is therefore rather surprising that three new Alaskan records should 

 be made for this species and its varieties in this collection. 



105. Lecanora atrosulphurea (Wahl.) Ach. 



Lichen afrosuipAureus Waui.ie.'sbkkg, F1. Lapp. 471. 1812.

Kadiak (Trelease, 891 a;, 896, 897, 898, 899 in part) ; Plover Bay, 

 Siberia (Trelease, 994). The specimens are all on rock. Those 

 from Kadiak are mixed with various species of Lecanora, Pcrtusaria^ 

 Buellia, and Lecidea. Nylander records it as occurring on St. Law- 

 rence Island. It has been collected in Arctic America and Greenland.

Alaska (Funston, 25a) ; Port Wells (Trelease, 935a;). The speci- 

 men from Port Wells is too old for satisfactory determination, but 

 seems better placed here than elsewhere. Rothrock's locality is Cape

 and Bering Island on the Siberian side of Bering Strait.
