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 ...
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.

Graphis scripta is a crustose lichen in the family Graphidaceae. It is commonly called script lichen, secret writing lichen, or similar names, because its growth pattern makes it looks like writing. [1] [2] Stigmidium microspilum and Arthonia graphidicola are associated lichenicolous fungi. [2] It is variable with either curved or stellate ...
This is possible due to the action of lichen phenolics such as usnic acid derivatives. [34] From the 1950s the lichen product usnic acid was the object of most antitumour research. These studies revealed some in vitro antitumour activity by substances identified in two common lichens Peltigera leucophlebia and Collema flaccidum. [35]
The alga bears its own scientific name, which has no relationship to the name of the lichen or fungus. [82] Depending on context, "lichenized fungus" may refer to the entire lichen, or to the fungus when it is in the lichen, which can be grown in culture in isolation from the algae or cyanobacteria.
Oakmoss (scientific name Evernia prunastri) is a species of lichen.It can be found in many mountainous temperate forests throughout the Northern Hemisphere.Oakmoss grows primarily on the trunk and branches of oak trees, but is also commonly found on the bark of other deciduous trees and conifers such as fir and pine.
A script lichen, or graphid lichen, is a member of a group of lichens which have spore producing structures that look like writing on the lichen body. [1] The structures are elongated and narrow apothecia called lirellae, which look like short scribbles on the thallus. [1] "Graphid" is derived from Greek for "writing". An example is Graphis ...
