Lepraria Granulata
''Lepraria granulata'' is a species of crustose and leprose lichen in the family Stereocaulaceae. It is found in mountainous locations of Eastern and Central Europe, where it usually grows over moss. Taxonomy ''Lepraria granulata'' was formally described as a new species in 2007 by Štěpánka Slavíková-Bayerová. The type specimen in Rila National Park (Rila mountains, Bulgaria) at an altitude of ; there, the lichen was found growing over the moss ''Grimmia sessitana'', which itself was covering siliceous rock. The species epithet ''granulata'' alludes to the granular form of the thallus. Molecular phylogenetic analysis shows it to be a genetically distinct member of the '' Lepraria neglecta'' species complex. Description The whitish grey to grey thallus of ''Lepraria granulata'' is crustose in form. It comprises tiny, loosely packed granules up to 0.3 mm in diameter, often without any hyphae projecting from them. The lichen is sterile, as neither ascomata nor ...

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 ...

Ascomata
An ascocarp, or ascoma (), is the fruiting body ( sporocarp) of an ascomycete phylum fungus. It consists of very tightly interwoven hyphae and millions of embedded asci, each of which typically contains four to eight ascospores. Ascocarps are most commonly bowl-shaped (apothecia) but may take on a spherical or flask-like form that has a pore opening to release spores (perithecia) or no opening (cleistothecia). Classification The ascocarp is classified according to its placement (in ways not fundamental to the basic taxonomy). It is called ''epigeous'' if it grows above ground, as with the morels, while underground ascocarps, such as truffles, are termed ''hypogeous''. The structure enclosing the hymenium is divided into the types described below (apothecium, cleistothecium, etc.) and this character ''is'' important for the taxonomic classification of the fungus. Apothecia can be relatively large and fleshy, whereas the others are microscopic—about the size of flecks of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grimmia Caespiticia
''Grimmia'' is a genus of mosses (Bryophyta), originally named by Jakob Friedrich Ehrhart in honour of Johann Friedrich Carl Grimm, a physician and botanist from Gotha, Germany. Geographic distribution Although predominantly occurring in the moderate zones, representatives of the cosmopolitan genus ''Grimmia'' may be found in all parts of the world, from Alaska to the most southern point of Chile, and from Siberia to South Africa, though in tropic regions, e.g. Hawaii and Indonesia, ''Grimmia'' species only occur high up in the mountains. Identification ''Grimmia'' is a notoriously difficult genus in terms of identification, and in the majority of herbaria a considerable number of species was found misidentified. The American bryologist Geneva Sayre (1911–1992), who worked for many years on a monograph of the North American ''Grimmias'', indicated in an original way these difficulties, as she said: "it contains an ambigua, a varia, a decipiens, a controversa, a revis ...

Tatra National Park, Slovakia
Tatra(s) National Park ( sk, Tatranský národný park; abbr. TANAP) is one of the nine national parks in Slovakia. It is situated in North Central Slovakia in the Tatra Mountains. The park is important for protecting a diverse variety of flora and fauna, with many endemic species, including the Tatra chamois. The Tatra Mountains form a natural border between Slovakia to the north and Poland to the south, and the two countries have cooperated since the early 20th century on efforts to protect the area. Poland created an adjoining national park, and UNESCO later designated the combined effort a transboundary biosphere reserve. Geography The Tatra National Park protects the Slovak areas of the High Tatras mountain range in the Eastern Tatras (''Východné Tatry'') ranges, and areas of the Western Tatras (''Západné Tatry'') ranges. The west part of the Tatra National Park is situated in the Žilina Region and the east part in the Prešov Region. The national park covers an a ...

Styria
Styria (german: Steiermark ; Serbo-Croatian and sl, ; hu, Stájerország) is a state (''Bundesland'') in the southeast of Austria. With an area of , Styria is the second largest state of Austria, after Lower Austria. Styria is bordered to the south by Slovenia, and clockwise, from the southwest, by the Austrian states of Carinthia, Salzburg, Upper Austria, Lower Austria, and Burgenland. The state capital is Graz. Etymology The March of Styria derived its name from the original seat of its ruling Otakar dynasty: Steyr, in today's Upper Austria. In German, the area is still called "Steiermark" while in English the Latin name "Styria" is used. The ancient link between Steyr and Styria is also apparent in their nearly identical coats of arms, a white Panther on a green background.

Spot Test (lichen)
A spot test in lichenology is a spot analysis used to help identify lichens. It is performed by placing a drop of a chemical on different parts of the lichen and noting the colour change (or lack thereof) associated with application of the chemical. The tests are routinely encountered in dichotomous keys for lichen species, and they take advantage of the wide array of lichen products produced by lichens and their uniqueness among taxa. As such, spot tests reveal the presence or absence of chemicals in various parts of a lichen. They were first proposed by the botanist William Nylander in 1866. Three common spot tests use either 10% aqueous KOH solution (K test), saturated aqueous solution of bleaching powder or calcium hypochlorite (C test), or 5% alcoholic ''p''-phenylenediamine solution (P test). The colour changes occur due to presence of particular secondary metabolites in the lichen. There are several other less frequently used spot tests of more limited use that are employed ...

Fatty Acid
In chemistry, particularly in biochemistry, a fatty acid is a carboxylic acid with an aliphatic chain, which is either saturated or unsaturated. Most naturally occurring fatty acids have an unbranched chain of an even number of carbon atoms, from 4 to 28. Fatty acids are a major component of the lipids (up to 70% by weight) in some species such as microalgae but in some other organisms are not found in their standalone form, but instead exist as three main classes of esters: triglycerides, phospholipids, and cholesteryl esters. In any of these forms, fatty acids are both important dietary sources of fuel for animals and important structural components for cells. History The concept of fatty acid (''acide gras'') was introduced in 1813 by Michel Eugène Chevreul, though he initially used some variant terms: ''graisse acide'' and ''acide huileux'' ("acid fat" and "oily acid"). Types of fatty acids Fatty acids are classified in many ways: by length, by saturation vs unsaturati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anthraquinone
Anthraquinone, also called anthracenedione or dioxoanthracene, is an aromatic organic compound with formula . Isomers include various quinone derivatives. The term anthraquinone however refers to the isomer, 9,10-anthraquinone (IUPAC: 9,10-dioxoanthracene) wherein the keto groups are located on the central ring. It is a building block of many dyes and is used in bleaching pulp for papermaking. It is a yellow, highly crystalline solid, poorly soluble in water but soluble in hot organic solvents. It is almost completely insoluble in ethanol near room temperature but 2.25 g will dissolve in 100 g of boiling ethanol. It is found in nature as the rare mineral hoelite. Synthesis There are several current industrial methods to produce 9,10-anthraquinone: # The oxidation of anthracene. Chromium(VI) is the typical oxidant. # The Friedel-Crafts reaction of benzene and phthalic anhydride in presence of AlCl3. o-Benzoylbenzoic acid is an intermediate. This reaction is useful for produc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
