Cladonia bellidiflora is an Arctic-alpine cup lichen producing reddish-tipped podetia emerging from a basal squamule layer on acidic soil and rock in high-altitude and high-latitude environments. It is found across Arctic and alpine zones in the Northern Hemisphere but is rare at its southern range margins. Critically Endangered in certain regions due to climate warming, habitat loss, and restricted distribution.
