HABITAT TYPES AND PLANT COMMUNITIES : 
Peltigera aphthosa occurs in various habitats, including open and closed
coniferous forests, lichen woodlands, bogs, and high arctic, low arctic,
sedge tussock, and shrub tundra [5,20,29,31,42].  In the southern extent
of its range, P. aphthosa is generally restricted to alpine regions.
The following publication classifies P. aphthosa as a dominant ground
cover species in lodgepole pine (Pinus contorta) and white spruce (Picea
glauca) habitats:
