Tubifera Ferruginosa
''Tubifera ferruginosa'', more commonly known as ''raspberry slime mold'' or ''red raspberry slime mold'', is a species of slime mold in the class (biology), class Myxogastria. It is one of the most widely known and distinct slime molds, being found throughout Temperate climate, temperate regions of the world, primarily in Europe and North America. Description ''T. ferruginosa'' is often found growing on damp rotten wood in temperate forests. It forms small, cushion-like "pseudoaethalia", or fruiting bodies from June to November that are bright red when young, and purple-brown when mature. These "pseudoaethalia" are different from the aethelia of other slime molds like Fuligo septica, because they are made of tightly bunched, gelatinous rods, or Sporangium, sporangia. Each individual sporangium is approximately 0.5 mm wide and 3 to 5 cm tall, while the width of the pseudoaethalia can reach 15 cm. The pseudoaethalia is anchored to a surface by the hypothallus, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
August Batsch
August Johann Georg Karl Batsch (28 October 1761 – 29 September 1802) was a German naturalist. He was a recognised authority on mushrooms, and also described new species of ferns, bryophytes, and seed plants. Life and career Batsch was born in Jena, Saxe-Weimar to George Lorenz Bratsch and Ernestine (''nee'' Franke) Bratsch. He studied at the Jena City School, and then had private tuition. He showed an aptitude for natural sciences and drawing, and so subsequently studied medicine and philosophy at the University of Jena (now known as the Friedrich Schiller University of Jena), entering in 1772 and obtaining his doctorate in philosophy in 1781 and in medicine in 1786, his supervisor being Justus Christian Loder. Batsch was married in 1787 to Amalie Pfaundel. They had three children, Friedrich (born 1789), George Friedrich Karl (1792), and Karoline (1795). He died in 1802 after a short illness. In 1786 Batsch began to teach natural history at the University of Jena and in 17 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slime Mold
Slime mold or slime mould is an informal name given to several kinds of unrelated eukaryotic organisms with a life cycle that includes a free-living single-celled stage and the formation of spores. Spores are often produced in macroscopic multicellular or multinucleate fruiting bodies which may be formed through aggregation or fusion. Slime molds were formerly classified as fungi but are no longer considered part of that kingdom. Although not forming a single monophyletic clade, they are grouped within the paraphyletic group Protista. More than 900 species of slime mold occur globally. Their common name refers to part of some of these organisms' life cycles where they can appear as gelatinous "slime". This is mostly seen with the Myxogastria, which are the only macroscopic slime molds. Most slime molds are smaller than a few centimetres, but some species may reach sizes up to several square metres and masses up to 20 kilograms. They feed on microorganisms that live in ...

Class (biology)
In biological classification, class ( la, classis) is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank. It is a group of related taxonomic orders. Other well-known ranks in descending order of size are life, domain, kingdom, phylum, order, family, genus, and species, with class fitting between phylum and order. History The class as a distinct rank of biological classification having its own distinctive name (and not just called a ''top-level genus'' ''(genus summum)'') was first introduced by the French botanist Joseph Pitton de Tournefort in his classification of plants that appeared in his ''Eléments de botanique'', 1694. Insofar as a general definition of a class is available, it has historically been conceived as embracing taxa that combine a distinct ''grade'' of organization—i.e. a 'level of complexity', measured in terms of how differentiated their organ systems are into distinct regions or sub-organs—with a distinct ''type'' of construction, ...

Myxogastria
Myxogastria/Myxogastrea (myxogastrids, International Code of Zoological Nomenclature, ICZN) or Myxomycetes (International Code of Nomenclature for algae, fungi, and plants, ICN), is a Class (biology), class of slime molds that contains 5 order (biology), orders, 14 family (biology), families, 62 genera, and 888 species. They are colloquially known as the ''plasmodial'' or ''acellular'' slime moulds. All species pass through several, very different morphology (biology), morphologic phases, such as microscopic individual cells, slimy amorphous organisms visible with the naked eye and conspicuously shaped fruit body, fruit bodies. Although they are monocellular, they can reach immense widths and weights: in extreme cases they can be up to across and weigh up to . The class Myxogastria is distributed worldwide, but it is more common in temperate regions where it has a higher biodiversity than in polar regions, the subtropics or tropics. They are mainly found in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperate Climate
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic ...

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Fuligo Septica
''Fuligo septica'' is a species of slime mold, and a member of the class Myxomycetes. It is commonly known as scrambled egg slime, or flowers of tan because of its peculiar yellowish appearance. It is also known as dog vomit slime mold, and is relatively common with a worldwide distribution, often being found on bark mulch in urban areas after heavy rain or excessive watering. Their spores are produced on or in aerial sporangia and are spread by wind. History and taxonomy The first description of the species was provided by French botanist Jean Marchant in 1727, who referred to it as "fleur de tan" (bark flower); Marchant also classified it as "des éponges" (one of the sponges). Carl Linnaeus called it ''Mucor septicus'' in his 1763 ''Species Plantarum''. The species was transferred to the genus ''Fuligo'' by German botanist Friedrich Heinrich Wiggers in 1780. Description and habitat Like many slime molds, the cells of this species typically aggregate to form a plasmodium, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sporangium
A sporangium (; from Late Latin, ) is an enclosure in which spores are formed. It can be composed of a single cell or can be multicellular. Virtually all plants, fungi, and many other lineages form sporangia at some point in their life cycle. Sporangia can produce spores by mitosis, but in nearly all land plants and many fungi, sporangia are the site of meiosis and produce genetically distinct haploid spores. Fungi In some phyla of fungi, the sporangium plays a role in asexual reproduction, and may play an indirect role in sexual reproduction. The sporangium forms on the sporangiophore and contains haploid nuclei and cytoplasm. Spores are formed in the sporangiophore by encasing each haploid nucleus and cytoplasm in a tough outer membrane. During asexual reproduction, these spores are dispersed via wind and germinate into haploid hyphae. Although sexual reproduction in fungi varies between phyla, for some fungi the sporangium plays an indirect role in sexual reprod ...

Hypothallus
In true slime molds (myxogastria), lichens, and in species of the family Clavicipitaceae, the hypothallus is the layer on which the fruit body sits, lying in contact with the substrate. The word is derived from the Ancient Greek root ''hypó'' ("under") and ''thallós'' ("shoot" or "thallus"). The hypothallus is produced by the plasmodium at the beginning of fructification. Depending on the species, it can be membranous to thick or tender to solid and nearly transparent to brightly coloured. It may surround an individual fruit body, or may form a contiguous connection between multiple fruit bodies. In some rare cases it is missing entirely. In crustose lichens, the hypothallus is the blackish lower layer of the thallus that produces rhizines, which are holdfasts that attach the lichen to its substrate. In some taxa the hypothallus may be involved in the formation of the fruit body. In the "epihypothallic" Stemonitida, the hypothallus forms hollow, tubular stems and a columella ...

Tubifera Ferruginosa 52288
''Tubifera'' is a genus of slime moulds from the subclass Myxogastria. The genus comprises 12 species. Description The fruit-bodies are aethalia formed from numerous, usually densely packed sporangia. The oblong sporangia are ochre, pink or red to dark brown and may be shiny or shimmering. They open at the tip to release the spores. The hypothallus is spongy, occasionally raised to a stem-like, stock, dark-coloured structure or also, on ''Tubifera bombarda'', soft and film-like thin. The membranous, single layered peridium outlasts the below half. A pseudocapillitium may or may not be present. The spores are light yellow to reddish-brown. Habitat ''Tubifera ferruginosa'' and '' Tubifera microsperma'' are more widespread and common than the other species from this genus. All species, except ''Tubifera casparyii'', are also common in the tropics. Classification The genus was circumscribed in 1873 by Józef Thomasz Rostafiński. The type species is ''Tubifera ferruginosa'', f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
