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 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 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.
The greenshields are a foliose type of lichen, a form that is leaf-like with flat sheets of tissue that can be peeled from the substrate, in the case of common greenshield, from the bark of a tree.
These include forage lichens (eaten by animals), nitrogen fixers (can take nitrogen molecules from the air and attach them to other molecules), acidophiles (acid loving lichens), wolf lichens, crustose lichens on rock, crustose lichens on bark and wood, biotic soil crusts, aquatic lichens, other green algal macrolichens, and pin lichens ”.
Lichens are grouped by thallus type, since the thallus is usually the most visually prominent part of the lichen. Thallus growth forms typically correspond to a few basic internal structure types. Common names for lichens often come from a growth form or color that is typical of a lichen genus. Common groupings of lichen thallus growth forms are:
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 ...
