Candelaria concolor: The Lemon Lichen

Candelaria concolor, commonly known as Lemon Lichen or Candleflame Lichen, is a widespread and easily overlooked organism often found during hikes in the woods.

Considerations for Pets

  • Lemon juice has been associated with adverse effects in cases of oral lichen planus, suggesting that direct exposure or ingestion of the lichen, if it contains similar compounds, might present some considerations.

Considerations for Children

  • The lichen is described as being small (0.1-0.5 mm wide), and its potential for being easily ingested by young children may warrant consideration.

Taxonomy and Nomenclature

  • Scientific Name: Candelaria concolor (Dicks.) Stein
  • Common Names: Lemon Lichen, Candleflame Lichen
  • Family: Candelariaceae
  • Group: Lichen
  • Rank: Species

Distribution and Habitat

  • Commonly found on bark in open areas.
  • Observed in locations such as Loughshinny, Dublin, Ireland, and Berkeley, California, USA.

Morphological Characteristics

  • Upper surface: Lemon yellow to mustard yellow, sometimes paling to yellow-green in shade.
  • Size: 0.1-0.5 (-1.2) mm wide.
  • Appearance: Described as having blotches with thin lines and white dots.

Ecological Role

  • Lichens are a symbiosis of fungi and algae, playing a role in various ecosystems.
  • Their presence can be an indicator of air quality; cleaner air supports lichen growth.

Interactions with Other Organisms

  • Lichens are a symbiotic relationship between a fungus (mycobiont) and an alga. The fungus provides structure and water retention, while the alga provides food through photosynthesis.
