Arctic Rock Tripe

Umbilicaria hyperborea

Also known as Blistered Rock Tripe, High Northern Rock Tripe

Arctic Rock Tripe forms dark charcoal to brown leathery sheets attached to exposed rocks by a single central anchor called an umbilicus. Its upper surface features distinctive raised blisters and folded wrinkles that help it survive extreme desiccation and icy winds. As a pioneer organism in polar and high-alpine environments, this resilient lichen slowly breaks down bare rock while providing vital ground cover in cold tundra ecosystems.
