Cladonia digitata: Finger Cup Lichen

Cladonia digitata, commonly known as Finger Cup Lichen or Fingered Pixie-cup Lichen, is a fascinating species of lichen belonging to the genus Cladonia. These lichens exhibit a unique morphology, featuring cup-like structures, and play a vital ecological role.

Considerations for Pets

  • The text mentions that Cladonia species are a primary food source for reindeer and caribou. While this suggests a degree of edibility for some animals, it doesn't guarantee safety for all pets.
