Lichen
A lichen ( , ) is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. Lichens have properties different from those of their component organisms. They come in many colors, sizes, and forms and are sometimes plant-like, but are not s. They may have tiny, leafless branches (); flat leaf-like structures ( |

Saxicolous Lichen
A saxicolous lichen is a lichen that grows on rock. The prefix "sax" from the Latin means "rock" or "stone". Characteristics Saxicolous lichens exhibit very slow growth rates. They may develop on rock substrates for long periods of time, given the absence of external disturbances. The importance of the mineral composition of the rock substrate, as well as the elemental geochemistry Geochemistry is the science that uses the tools and principles of chemistry to explain the mechanisms behind major geological systems such as the Earth's crust and its oceans. The realm of geochemistry extends beyond the Earth, encompassing the e ... is also important to the distribution of saxicolous lichens, but the relationship between the substrate influence on lichens, either chemical or textural, is still obscure. Communities of saxicolous lichens are often species-rich in terms of number. References Lichenology {{lichen-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphis Plumierae
''Graphis plumierae'' is a species of script lichen in the family Graphidaceae. It was described as new to science in 1915 by Finnish mycologist Edvard Vainio. The type was collected in Gourbeyre, Guadeloupe. In 2016, ''G. plumierae'' was reported from Portugal, which was also a new occurrence for Europe. ''Graphis plumierae'' has labia that are white-pruinose. The lirellae (these are ascomata with a long, narrow disc resembling dark squiggly lines), which are immersed in the substrate, have a lateral thalline margin. The lichen contains the secondary compounds norstictic acid, stictic, and salazinic acid Salazinic acid is a depsidone with a lactone ring. It is found in some lichens, and is especially prevalent in ''Parmotrema'' and ''Bulbothrix'', where its presence or absence is often used to help classify species in those genera. History I ....

Melanohalea Subolivacea
''Melanohalea subolivacea'', commonly known as the brown-eyed camouflage lichen, is a species of foliose lichen in the family Parmeliaceae. Taxonomy The lichen was first documented by Finnish lichenologist William Nylander. The type specimen was found growing on rocks in the San Gabriel Mountains of Southern California, at an elevation of . The lichen was formally described in a publication by American lichenologist Hermann Edward Hasse in 1897, with authorship attributed to Nylander. Named for its resemblance to '' Parmelia olivacea'', it was distinguished from that species by its spore size, measuring 8–9 by 5 μm. It was transferred to the genus ''Melanelia'' by Ted Esslinger in 1978, and then to the newly circumscribed genus '' Melanohalea'' in 2004. ''Melanohalea subolivacea'' has been given the common name "brown-eyed camouflage lichen". Molecular phylogenetic studies of '' Melanohalea'' species show that ''Melanohalea subolivacea'' is closely related, but genetic ...
