Letharia columbiana (common name brown-eye wolf lichen) is a common lichen in subalpine forests, particularly in the Pacific Northwest of the United States, and parts of Canada. [1] It is in the family Parmeliaceae, and the genus Letharia. Its characteristics include a bright citron color, “brown-eyes”, and rounded, irregular branches. [2]
Letharia vulpina, commonly known as the wolf lichen (although the species name vulpina, from vulpine relates to the fox), is a fruticose lichenized species of fungus in the family Parmeliaceae. It is bright yellow-green, shrubby and highly branched, and grows on the bark of living and dead conifers in parts of western and continental Europe and ...
Letharia is a genus of fruticose lichens belonging to the family Parmeliaceae. [2]There were historically two species of Letharia: L. vulpina and L. columbiana. [3] Recent molecular sequence studies published in 2016 confirm at least 6 species in Western North America alone, with more expected to be confirmed using similar methods in other parts of the world.
These lichens are yellow because they have high concentrations of the bright yellow toxin vulpinic acid. Wolf lichen (Letharia vulpina) was used in Scandinavia to poison wolves. The process begins by adding the lichens to various baits such as reindeer blood and other meats, while sometimes mixing the concoction with ground glass or strychnine ...
A lichen (/ ˈ l aɪ k ən / LIE-kən, UK also / ˈ l ɪ tʃ ən / LI-chən) is a hybrid colony of algae or cyanobacteria living symbiotically among filaments of multiple fungi species, along with yeasts and bacteria [1] [2] embedded in the cortex or "skin", in a mutualistic relationship.
Bryoria fremontii is a dark brown, horsehair lichen that grows hanging from trees in western North America, and northern Europe and Asia. It grows abundantly in some areas, and is an important traditional food for a few First Nations in North America.
Melanelia hepatizon, commonly known as the rimmed camouflage lichen or the rimmed brown-shield, is a species of saxicolous (rock-dwelling), foliose lichen in the family Parmeliaceae. [2] Its thallus , ranging in colour from brown to black, features narrow, elongated lobes that can be flat, convex, or concave.
Lecidea atrobrunnea is a group of lichen-forming fungi in the family Lecideaceae.Previously though to represent a single, widely distributed crustose lichen, recent research has shown that the name represents many unique lineages of morphologically and chemically variable lichen-forming fungi that have not yet been precisely characterized.
