Lepidocollema Marianum
''Lepidocollema marianum'' is a species of cyanolichen in the family Pannariaceae. It was first scientifically described by Elias Fries in 1825 as ''Parmelia mariana''. Per Magnus Jørgensen transferred it to the genus ''Lepidocollema'' in 2014 following a molecular phylogenetics-guided revision of the Pannariaceae. The lichen has a growth form that is both squamulose (scaley) and foliose (leafy), with lobes around the margins and squamules in the centre of the thallus. It is firmly attached to the underlying substratum by root-like rhizines, which are brown to black in colour; the hypothallus is also black. ''Lepidocollema marianum'' occurs in Asia (including Thailand, Sri Lanka, and Taiwan) and Mauritius Mauritius ( ; french: Maurice, link=no ; mfe, label=Mauritian Creole, Moris ), officially the Republic of Mauritius, is an island nation in the Indian Ocean about off the southeast coast of the African continent, east of Madagascar.

Elias Magnus Fries
Elias Magnus Fries (15 August 1794 – 8 February 1878) was a Swedish mycologist and botanist. Career Fries was born at Femsjö (Hylte Municipality), Småland, the son of the pastor there. He attended school in Växjö. He acquired an extensive knowledge of flowering plants from his father. In 1811 Fries entered Lund University where he obtained a doctorate in 1814. In the same year he was appointed an associate professorship in botany. He was elected a member of the Royal Swedish Academy of Sciences, and in 1824, became a full professor. In 1834 he became Borgström professor (Swed. ''Borgströmianska professuren'', a chair endowed by Erik Eriksson Borgström, 1708–1770) in applied economics at Uppsala University. The position was changed to "professor of botany and applied economics" in 1851. He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1849. That year he was also appointed director of the Uppsala University Botanica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thallus
Thallus (plural: thalli), from Latinized Greek (), meaning "a green shoot" or "twig", is the vegetative tissue of some organisms in diverse groups such as algae, fungi, some liverworts, lichens, and the Myxogastria. Many of these organisms were previously known as the thallophytes, a polyphyletic group of distantly related organisms. An organism or structure resembling a thallus is called thalloid, thallodal, thalliform, thalline, or thallose. A thallus usually names the entire body of a multicellular non-moving organism in which there is no organization of the tissues into organs. Even though thalli do not have organized and distinct parts (leaves, roots, and stems) as do the vascular plants, they may have analogous structures that resemble their vascular "equivalents". The analogous structures have similar function or macroscopic structure, but different microscopic structure; for example, no thallus has vascular tissue. In exceptional cases such as the Lemnoideae, where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Species Fungorum
''Index Fungorum'' is an international project to index all formal names (scientific names) in the fungus kingdom. the project is based at the Royal Botanic Gardens, Kew, one of three partners along with Landcare Research and the Institute of Microbiology, Chinese Academy of Sciences. It is somewhat comparable to the International Plant Names Index (IPNI), in which the Royal Botanic Gardens is also involved. A difference is that where IPNI does not indicate correct names, the ''Index Fungorum'' does indicate the status of a name. In the returns from the search page a currently correct name is indicated in green, while others are in blue (a few, aberrant usages of names are indicated in red). All names are linked to pages giving the correct name, with lists of synonyms. ''Index Fungorum'' is one of three nomenclatural repositories recognized by the Nomenclature Committee for Fungi; the others are ''MycoBank'' and ''Fungal Names''. Current names in ''Index Fungorum'' (''Specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mauritius
Mauritius ( ; french: Maurice, link=no ; mfe, label=Mauritian Creole, Moris ), officially the Republic of Mauritius, is an island nation in the Indian Ocean about off the southeast coast of the African continent, east of Madagascar. It includes the main island (also called Mauritius), as well as Rodrigues, Agaléga and St. Brandon. The islands of Mauritius and Rodrigues, along with nearby Réunion (a French overseas department), are part of the Mascarene Islands. The main island of Mauritius, where most of the population is concentrated, hosts the capital and largest city, Port Louis. The country spans and has an exclusive economic zone covering . Arab sailors were the first to discover the uninhabited island, around 975, and they called it ''Dina Arobi''. The earliest discovery was in 1507 by Portuguese sailors, who otherwise took little interest in the islands. The Dutch took possession in 1598, establishing a succession of short-lived settlements over a period of about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhizine
In lichens, rhizines are multicellular root-like structures, arising mostly from the lower surface. A lichen with rhizines is termed rhizinate, while a lichen lacking rhizines is termed erhizinate. Rhizines serve only to anchor the lichen to their substrate; they do not absorb nutrients as do plant roots. Characteristics of the rhizines are used to identify lichens, for example: whether they are dense or sparse, whether they are uniformly distributed or clumped in specific areas, and whether they are straight or branched. Only foliose lichens may possess rhizines, not crustose or fruticose lichens, which lack a lower cortex. Rhizohyphae are a type of attachment structure on some lichens. Rhizohyphae are more slender than rhizines and are one cell thick in diameter. Rhizohyphae often occur as a felt-like hyphal mass. See also *Rhizoid Rhizoids are protuberances that extend from the lower epidermal cells of bryophytes and algae. They are similar in structure and function to the ro ...

Foliose Lichen
Foliose lichen is one of the morphological classes of lichens, which are complex organisms that arise from the symbiotic relationship between fungi and a photosynthetic partner, typically algae. This partnership allows lichen to live in diverse climates that can range from cold, dry mountains to wet, warm valleys. Lichens develop quite slowly with recorded growth rates of 0.01–27mm/year depending on the species. Their lifespan averages between 30 and 60 years. Lichens have a main body part called the thallus, which is composed of hyphae, and houses the cortex and medulla. The cortex contains the photosynthetic cells while the medulla allows for gas exchange and makes up the bulk of the lichen's thallus. There are three main types of lichens: crustose, foliose, and fruticose. Foliose lichen are characterised by flattened leafy thalli, and an upper and lower cortex. Many have numerous layers, which are stratified, and aid in identifying different types. Foliose lichens attach to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squamulose Lichen
A squamulose lichen is a lichen that is composed of small, often overlapping "scales" called squamules. If they are raised from the substrate and appear leafy, the lichen may appear to be a foliose lichen, but the underside does not have a "skin" (cortex), as foliose lichens do. Squamulose lichens are composed of flattish units that are usually tightly clustered. They are like an intermediate between crustose Crustose is a habit of some types of algae and lichens in which the organism grows tightly appressed to a substrate, forming a biological layer. ''Crustose'' adheres very closely to the substrates at all points. ''Crustose'' is found on rocks ... and foliose lichens. Examples of squamulose lichen include '' Vahliella leucophaea'', '' Cladonia subcervicornis'' and '' Lichenomphalia hudsoniana''. References Lichenology {{lichen-stub ...
