Common Goldspeck

<em>Candelariella vitellina</em>, commonly known as common goldspeck, is a crustose lichen belonging to the genus Candelariella within the family Candelariaceae. This species inhabits ecosystems across Europe and North America and South America, reflecting a broad geographic tolerance suited to its saxicolous lifestyle. Its known range includes populations in four European countries, the United States in North America, and Colombia in South America. The species is assessed as Least Concern on the IUCN Red List, indicating that current population trends do not suggest elevated extinction risk. Common goldspeck typically colonizes exposed rock surfaces, bark, and other firm substrates in open environments where light availability supports its photosynthetic activity. Biological traits of this species remain poorly documented in the scientific literature.
