Lecideales Genera
The Lecideales are an order of lichenized fungi in the class Lecanoromycetes. The order contains two families: the ''Lecideaceae The Lecideaceae are a family (biology), family of lichen-forming fungi in the order Lecideales. It contains about 30 genus, genera and roughly 250 species. A major distinguishing characteristic of the family is the form of the ascomata, fruit ...'', which contains 29 genera and about 260 species, and Lopadiaceae, which contains the single genus '' Lopadium'' of 10 species. According to Alan Fryday and colleagues in the ''Revisions of British and Irish Lichens'' series, "It seems clear that Lopadiaceae does not belong in Lecideales but its true systematic position is unclear."

Lecidea Atrobrunnea
''Lecidea atrobrunnea'' is a group of lichen-forming fungi in the family Lecideaceae. Previously though to represent a single, widely distributed crustose lichen, recent research has shown that the name represents many unique lineages of morphologically and chemically variable lichen-forming fungi that have not yet been precisely characterized. Members of this group are most diverse in mountains of the continental western United States and Alaska. With other lichen communities, it forms dark vertical drip-like stripings along drainage tracks in the rock faces, resulting in Native Americans giving the name " Face of a Young Woman Stained with Tears" to Half Dome. This combined lichen community appears black from a distance, but brown up close. It varies greatly in its overall appearance from colony to colony. ''L atrobrunnea'' subsp. ''atrobrunnea'' has been found to be common in very common in high montane zones and alpine zones. ''L atrobrunnea'' subsp. ''saxosa'' ("saxosa" mea ...

Lecidea Laboriosa
''Lecidea laboriosa'' is a species of lichen that grows inside solid rock (endolithic), with only the small black disc-like fruiting bodies (apothecia) visible above the rock surface.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, Lichen Flora of the Greater Sonoran Desert Region. Vol 2, Nash, T.H., Ryan, B.D., Gries, C., Bugartz, F., (eds.) 2001/ref> Unlike other members of the genus ''Lecidea'', the apothecia are not lecideine in that they either lack black margins ( exciples) or have gray vertically striated margins. It grows all over the world in all climates. It might be the most common endolithic lichen in California California () is a U.S. state, state in the Western United States that lies on the West Coast of the United States, Pacific Coast. It borders Oregon to the north, Nevada and Arizona to the east, and shares Mexico–United States border, an .... It is similar in appearance to '' Catillaria lenticularis'', '' Polyspora ...

Lecidea Keimioeensis
''Lecidea keimioeensis'' (originally published as ''keimioeënsis'') is a species of crustose lichen. It was collected by Finnish botanist Kaarlo Linkola from , Finland, (for which the species is named), and identified as a new species by Edvard August Vainio. This species was the last one described by Vainio before he had to go to the hospital for a sudden illness, where he died two weeks later. Since its original publication, it has scarcely been reported in the scientific literature. In a 1997 assessment report about the inclusion criteria for a Finnish Regional Red List A Regional Red List is a report of the threatened status of species within a certain country or region. It is based on the IUCN Red List of Threatened Species, an inventory of the conservation status of species on a global scale. Regional Red ..., the species was described as an example of "probably curiosities known to only one researcher". See also * List of ''Lecidea'' species References keim ...

Lecidea Hassei
''Lecidea hassei'' (Hasse's lecidea lichen) is an endolithic lichen that appears as tiny black, gray rimmed, plate-like or crinkled discs between crystals of rock in California. The main body grows ''inside'' solid rock (endolithic), and the crinkled discs above the rock surface are the sexual reproduction structures. It is endemic to California, where it only grows in the lower montane belt, including in deserts and chaparral.The Lichen Flora of Joshua Tree National Park An Annotated Checklist, Kerry Knudsen, Mitzi Harding, Josh Hoines, National Park Service/ref> It occurs in Joshua Tree National Park. The sexual reproduction structures (apothecia) are black, thinly rimmed (70–100 μm ) with unpigmented fungal tissue surrounding black discs in the middle, and up to 2.2 mm in diameter. They rise out of the rock in a flat to convex disc with a constricted base, giving the appearance of tiny raised plates. It grows in open areas on granite, schist, and other acidic ro ...

Crustose Lichen
Crustose lichens are lichens that form a crust which strongly adheres to the Substrate (biology), substrate (soil, rock, tree bark, etc.), making separation from the substrate impossible without destruction. The basic structure of crustose lichens consists of a cortex (botany), cortex layer, an algal layer, and a medulla. The upper cortex layer is differentiated and is usually pigmented. The algal layer lies beneath the cortex. The medulla fastens the lichen to the substrate and is made up of Fungus, fungal hyphae. The surface of crustose lichens is characterized by branching cracks that periodically close in response to climatic variations such as alternate wetting and drying regimes. Subtypes * Powdery – considered as the simplest subtype due to the absence of an organized thallus. :The thallus appears powdery. :E.g. Genera ''Lepraria'', ''Vezdaea'' * Endolithic – grows inside the rock, usually in interstitial spaces between mineral grains. The :upper cortex is usually d ...

List Of Common Names Of Lichen Genera
This is a list of common names of lichen genera. When a common name for a lichen genus is the same as the scientific name for that genus, it is not included in the following list. This list only includes genera common names that are widely used, as indicated by the common name either appearing in a peer reviewed scientific publication or in a scientifically reliable reference source. A common name for a lichen genus will often uniquely refer to that genus, but not always. Sometimes the same common name may refer to several different genera, which may not be related by sharing common ancestry. An example is that " wart lichen" refers to at least five different genera in four different families. Sometimes the same genus may have more than one widely used common name. For example, members of the genus '' Staurothele'' are commonly called " wart lichens", and also " rock pimples". Lichen genus common names my come from the shape, color, or other feature of some members of a genus. Othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
