Spot tests on the foliose lichen Punctelia borreri showing thallus (top) and medulla (bottom). The pinkish-red colour change of the medulla in the C and KC tests indicate the presence of gyrophoric acid, a chemical feature that helps to distinguish it from similar species in the same genus.
Methods for species identification include reference to single-access keys on lichens. An example reference work is Lichens of North America (2001) by Irwin M. Brodo, Sylvia Sharnoff and Stephen Sharnoff and that book's 2016 expansion, Keys to Lichens of North America: Revised and Expanded by the same three authors joined by Susan Laurie ...
Edible lichens are lichens that have a cultural history of use as a food. Although almost all lichen are edible (with some notable poisonous exceptions like the wolf lichen , powdered sunshine lichen , and the ground lichen [ 1 ] ), not all have a cultural history of usage as an edible lichen.
The IAL has established various committees to address specific aspects of lichenology. The Lichen Terminology Committee, for instance, was responsible for developing an IAL-approved definition of a lichen: "A lichen is an association of a fungus and a photosynthetic symbiont resulting in a stable thallus of specific structure". [3]
The lichen's ability to endure and adapt to rapid temperature changes and hydration levels is critical for its survival in these alpine conditions. During chinook wind events, for instance, the lichen experiences swift transitions from heavy snowfall to melting conditions, leading to brief but significant periods of hydration essential for ...
Arthonia radiata is a crustose lichen with an immersed thallus, often separated from its surroundings by a thin brown line.The thallus is typically pale, ranging from white to pale grey, sometimes with a brown or olive tinge, and often forms a mosaic-like pattern on its substrate.
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 ...
Verseghya thysanophora, commonly known as the mapledust lichen, is a species of mostly corticolous (bark-dwelling), leprose lichen in the family Pertusariaceae. [2] This common species is widely distributed in the Northern Hemisphere. The thallus of the lichen is a thin patchy layer of granular soredia, pale green
