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 vulpina, the wolf lichen. Only a few lichens are truly poisonous, with species of Letharia and Vulpicida being the primary examples. 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.
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.
Although there are many lichen species throughout the world, only a few species of lichen are known to be both edible and provide any nutrition. [6] Two problems often encountered with eating lichens is that they usually contain mildly toxic secondary compounds, and that lichen polysaccharides are generally indigestible to humans. Many human ...
Usnea filipendula – one of about 20,000 described species of lichen. The following outline provides an overview of and topical guide to lichens.. Lichen – composite organism made up of multiple species – a fungal partner, one or more photosynthetic partners, which can be either green algae or cyanobacteria, and, in at least 52 genera of lichens, a yeast.

But sometimes the parts of a lichen species common name are common names of other lichen genera. For example, Psilolechia lucida, in the genus Psilolechia, is commonly called "sulphur dust lichen". [1] [2] But "sulphur lichen" refers to the genus Fulgensia, and "dust lichen" refers either to the genus Chrysothrix or the genus Lepraria. [1] [3 ...
