Phlyctis: The Blemished Lichen

Phlyctis is a fascinating genus of fungi belonging to the order Ostropales. Commonly known as "blemished lichens," these organisms often go unnoticed, yet play a crucial role in various ecosystems.

Taxonomy and Nomenclature

  • Genus: Phlyctis
  • Common Name: Blemished Lichen
  • Family: Phlyctidaceae
  • Kingdom: Fungi

Species Examples

  • Phlyctis argena (synonym: Lichen agelaeus) - Also known as Whitewash Lichen
  • Phlyctis speirea
  • Phlyctis willeyi

Distribution and Habitat

  • Phlyctis argena, a crustose lichen, typically grows on deciduous trees like red maple but can sometimes be found on conifers.

Quirky Facts

  • The appearance of lichens on trees, including Phlyctis, can be an indicator of the tree's overall health and vigor. A heavy build-up may suggest the tree is low in vigor.
  • Dust lichens can sometimes be mistaken for Phlyctis argena.

Ecological Role

  • Lichens, including Phlyctis species, contribute to biodiversity and provide microhabitats for other organisms.

Interactions with Other Organisms

  • Lichens, in general, can be affected by fungi causing blemish diseases on fruit trees.
