Reticulate Cetraria Lichen

The Reticulate Cetraria Lichen, scientifically known as Cetraria ericetorum Opiz subsp. reticulata (Rasanen) Karnefelt, is a fascinating lichen species. This page provides an overview of its classification, distribution, and other interesting facts.

Taxonomy and Nomenclature

  • Scientific Name: Cetraria ericetorum Opiz subsp. reticulata (Rasanen) Karnefelt
  • Common Names: Reticulate Cetraria Lichen, Cetraria Lichen
  • Rank: Subspecies
  • Family: Parmeliaceae
  • Synonyms: Mentions within the text suggest relationships to the Cetraria ericetorum complex.
  • Other Scientific Names Mentioned: Cetraria ericetorum Opiz, Cetraria Canadensis (Rasanen) Rasanen, Cetraria Oakesiana var. spinulosa Merrill

Distribution and Habitat

Cetraria ericetorum subsp. reticulata is often found at high latitudes, typically growing on sand or heath. It has been observed in:

  • British Columbia, Canada (near Dunn Peak, north of Kamloops)
  • Alpine environments alongside the net-veined willow (Salix reticulata)
  • Northern high Andes and Costa Rica (though this may refer to the genus Cetraria in general)

Morphological Characteristics

  • Belongs to the genus Cetraria, which are fruticose (shrub-like) lichens.
  • The thallus (lichen body) exhibits a reticulate (net-like) pattern. In some species the base of the thallus can be yellow-orange in color.

Interactions with Other Organisms

  • Cetraria lichens associate with green algae as photobionts (organisms that provide food through photosynthesis).
  • Found in habitats together with net-veined willow (Salix reticulata).
  • Some lichens in the Parmeliaceae family, to which Cetraria belongs, may have an allelopathic potential.

Quirky Facts

  • The type locality of subspecies reticulata is given as "Kamloops," hinting at its prevalence in that region.
  • Historically, some lichen species, including those related to Cetraria, have been used in traditional medicine.
