Dendriscocaulon umhausense

Dendriscocaulon umhausense is a lichen belonging to the Ascomycota phylum, sometimes referred to as "Thorn Lichen." This lichen has a complex relationship with other lichens, particularly Lobaria amplissima.

Considerations for Pets

  • This lichen has fine white hairs on its branching irregular sides.

Taxonomy and Nomenclature

  • Scientific Name: Dendriscocaulon umhausense (Auersw.) Degel.
  • Rank: Species
  • Family: Lobariaceae
  • Phylum: Ascomycota (Sac Fungi)
  • Synonyms:
    • Cornicularia umhausensis Auersw.
    • Dendriscocaulon bolacinum (Ach.) Nyl.
    • Homodium bolacinum (Ach.) Cromb.
    • Polychidium umhausense (Auersw.) Henssen
    • Leptogidium intricatulum Nyl.
    • Polychidium intricatulum (Nyl.) Henssen

Morphology and Growth Habits

  • The thallus (body) is small and fruticose (shrub-like).
  • It is typically brown, becoming paler in shaded areas inside the cushion-like mass it forms.
  • The tips are coralloid (coral-like) with irregular branching.
  • Fine white hairs are present on the sides of the branches.
  • It forms a coral-like tuft.

Distribution and Habitat

  • It has been found in locations ranging from Norway to the Mediterranean mountains, always in humid areas.
  • It can be found in Metropolitan France and Overseas territories.

Ecological Role

  • Dendriscocaulon umhausense can exist separately as a different lichen species when cephalodia drop off from parent lichens.
  • It may exist on Lobaria amplissima.

Quirky Facts

  • The taxonomic relationship between Dendriscocaulon umhausense and Lobaria amplissima is complex. Molecular studies suggest that the mycobionts (fungal partners) of Dendriscocaulon umhausense and the chlorolichen L. amplissima are identical, even though they appear very different.
  • Sometimes it is called Dendriscocaulon intricatulum when having respective synonyms Polychidium umhausense and Polychidium intricatulum.
