One hundred eighty-two taxa of lichens including two lichen parasites are reported from Izembek National Wildlife Refuge on the tip of the Alaska Peninsula. Metasphaeria tartarina is new to North America; Scoliciosporum umbrinum is new to Alaska. Wide-ranging, arctic-alpine, and boreal species dominate the lichen flora; a coastal element is moderately represented, while amphi-Beringian species form a minor element. Epigeic lichen abundance is described along a lowland to alpine mesotopographic gradient selected to represent major landscape variation in the refuge. Of six major community types identified, three had significant lichen components.
