Cladonia Squamosa
''Cladonia squamosa'' or the dragon cup lichen is a species of Cladonia, cup lichen in the family Cladoniaceae. Description The primary thallus is composed of medium-sized, crenate squamules, approximately 1.5-7mm. long, and 1-5mm. wide. The upper surface is fawn (color), fawn or Tan (color), tan to cinnamon-colored varying toward greenish grey. The apothecia are small, ranging from .5–3 mm. in diameter, and are located on the margin of the cups or at the ends of branches or proliferations. They are fawn (color), fawn to cinnamon-colored. The paraphyses are usually simple, sometimes thickened, and are brownish towards the apex. The hymenium is pale or pale-brownish below and brownish above. The Ascus, asci are lecanoralean, with a thickened tholus. There are a usually 8 ascospores, which are oblong or oblong-obtuse to fusiform in shape, between 5-17 μm. long and 2.5-3.5 μm. wide. Conidia are falcate and 3-8 μm. long.Fink, Bruce (1907). Further Notes on Clad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scop
A ( or ) was a poet as represented in Old English poetry. The scop is the Old English counterpart of the Old Norse ', with the important difference that "skald" was applied to historical persons, and scop is used, for the most part, to designate oral poets ''within'' Old English literature. Very little is known about scops, and their historical existence is questioned by some scholars. Functions The scop, like the similar gleeman, was a reciter of poetry. The scop, however, was typically attached to a court on a relatively permanent basis. There, he most likely received rich gifts for his performances. The performances often featured the recitation of recognisable texts such as the "old pagan legends of the Germanic tribes." However, the scop's duties also included ''composing'' his own poetry in different situations, the eulogizing of his master. While some scops moved from court to court, they were (generally speaking) less nomadic than the gleemen and had positions of gre ...

Conidia
A conidium ( ; ), sometimes termed an asexual chlamydospore or chlamydoconidium (), is an asexual, non-motile spore of a fungus. The word ''conidium'' comes from the Ancient Greek word for dust, ('). They are also called mitospores due to the way they are generated through the cellular process of mitosis. The two new haploid cells are genetically identical to the haploid parent, and can develop into new organisms if conditions are favorable, and serve in biological dispersal. Asexual reproduction in ascomycetes (the phylum Ascomycota) is by the formation of conidia, which are borne on specialized stalks called conidiophores. The morphology of these specialized conidiophores is often distinctive between species and, before the development of molecular techniques at the end of the 20th century, was widely used for identification of (''e.g.'' ''Metarhizium'') species. The terms microconidia and macroconidia are sometimes used. Conidiogenesis There are two main types of conidium ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terpenoids
The terpenoids, also known as isoprenoids, are a class of naturally occurring organic chemicals derived from the 5-carbon compound isoprene and its derivatives called terpenes, diterpenes, etc. While sometimes used interchangeably with "terpenes", terpenoids contain additional functional groups, usually containing oxygen. When combined with the hydrocarbon terpenes, terpenoids comprise about 80,000 compounds. They are the largest class of plant secondary metabolites, representing about 60% of known natural products. Many terpenoids have substantial pharmacological bioactivity and are therefore of interest to medicinal chemists. Plant terpenoids are used for their aromatic qualities and play a role in traditional herbal remedies. Terpenoids contribute to the scent of eucalyptus, the flavors of cinnamon, cloves, and ginger, the yellow color in sunflowers, and the red color in tomatoes. Well-known terpenoids include citral, menthol, camphor, salvinorin A in the plant '' Salvia divino ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terpenes
Terpenes () are a class of natural products consisting of compounds with the formula (C5H8)n for n > 1. Comprising more than 30,000 compounds, these unsaturated hydrocarbons are produced predominantly by plants, particularly conifers. Terpenes are further classified by the number of carbons: monoterpenes (C10), sesquiterpenes (C15), diterpenes (C20), as examples. The terpene alpha-pinene, is a major component of the common solvent, turpentine. History and terminology The term ''terpene'' was coined in 1866 by the German chemist August Kekulé to denote all hydrocarbons having the empirical formula C10H16, of which camphene was one. Previously, many hydrocarbons having the empirical formula C10H16 had been called "camphene", but many other hydrocarbons of the same composition had had different names. Kekulé coined the term "terpene" in order to reduce the confusion. The name "terpene" is a shortened form of "terpentine", an obsolete spelling of "turpentine". Although sometimes u ...

Barbatic Acid
Barbatic acid is an organic compound that is made by some lichens. It is in the structural class known as depsides. It is particularly common in the genera ''Usnea'' (the beard lichens) and ''Cladonia''. History The compound was first isolated in 1880 from the lichen '' Usnea barbata'' by chemists John Stenhouse and Charles Groves. The compound coccellic acid, isolated from '' Cladonia coccifera'', was later shown to be the same compound as barbatic acid. Properties Biosynthetically, barbatic acid is made of two units of orsellinate derivatives that are created by an aromatic synthase enzyme. The repeated action of this enzyme produces an 8-carbon polyketide intermediate that is cyclized. Barbatic acid's IUPAC name is 2-hydroxy-4-(2-hydroxy-4-methoxy-3,6-dimethylbenzoyl)oxy-3,6-dimethylbenzoic acid. Its chemical formula is C19H20O7; it has a molecular mass of 360.36 grams per mole. In its purified crystalline form, it exists as various forms: small rhombic prisms, lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cladonia Squamosa-3
''Cladonia'' is a genus of moss-like lichens in the family Cladoniaceae. They are the primary food source for reindeer/caribou. ''Cladonia'' species are of economic importance to reindeer-herders, such as the Sami in Scandinavia or the Nenets in Russia. Antibiotic compounds are extracted from some species to create antibiotic cream. The light green species '' Cladonia stellaris'' is used in flower decorations. Although the phylogeny of the genus ''Cladonia'' is still under investigation, two main morphological groups are commonly differentiated by taxonomists: the ''Cladonia'' morpho-type and the ''Cladina'' morpho-type. The ''Cladonia'' morpho-type has many more species, and is generally described as a group of squamulose (grow from squamules), cup-bearing lichens. The ''Cladina'' morpho-types are often referred to as forage lichens, mat-forming lichens, or reindeer lichens (due to their importance as caribou winter forage).

Andrea Gainii
Andrea is a given name which is common worldwide for both males and females, cognate to Andreas, Andrej and Andrew. Origin of the name The name derives from the Greek word ἀνήρ (''anēr''), genitive ἀνδρός (''andrós''), that refers to man as opposed to woman (whereas ''man'' in the sense of ''human being'' is ἄνθρωπος, ''ánthropos''). The original male Greek name, ''Andréas'', represents the hypocoristic, with endearment functions, of male Greek names composed with the ''andr-'' prefix, like Androgeos (''man of the earth''), Androcles (''man of glory''), Andronikos (''man of victory''). In the year 2006, it was the third most popular name in Italy with 3.1% of newborns. It is one of the Italian male names ending in ''a'', with others being Elia ( Elias), Enea ( Aeneas), Luca (Lucas), Mattia (Matthias), Nicola (Nicholas), Tobia ( Tobias). In recent and past times it has also been used on occasion as a female name in Italy and in Spain, where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polytrichum Strictum
''Polytrichum strictum'', commonly known as bog haircap moss or strict haircap, is an evergreen and perennial species of moss native to ''Sphagnum'' bogs and other moist habitats in temperate climates. It has a Circumboreal Region, circumboreal distribution, and is also found in South America and Antarctica. Description Like other species in the Polytrichaceae, ''Polytrichum strictum'' has leaves with a single costa, vertical Lamella (surface anatomy), lamellae, a water-repelling cuticle, and rhizoids that appear to facilitate external water movement in addition to anchoring the plant. Dense tufts of slender stems from 6–12 cm form 20–40 cm hummocks in bogs and similar substrates. Leaves are narrowly lanceolate, appressed to the stem when dry and spreading to erect when moist. The reddish awn (formed by the slightly excurrent costa) and smooth, inrolled leaf margins separate ''P. strictum'' from other Polytrichum species; only Polytrichum juniperinum, juniper ha ...
