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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jena
Jena (; ) is a List of cities and towns in Germany, city in Germany and the second largest city in Thuringia. Together with the nearby cities of Erfurt and Weimar, it forms the central metropolitan area of Thuringia with approximately 500,000 inhabitants, while the city itself has a population of about 110,000. Jena is a centre of education and research. The University of Jena (formally the Friedrich Schiller University) was founded in 1558 and had 18,000 students in 2017 and the Ernst-Abbe-Hochschule Jena serves another 5,000 students. Furthermore, there are many institutes of the leading German research societies. Jena was first mentioned in 1182 and stayed a small town until the 19th century, when industry developed. For most of the 20th century, Jena was a world centre of the optical industry around companies such as Carl Zeiss AG, Carl Zeiss, Schott AG, Schott and Jenoptik (since 1990). As one of only a few medium-sized cities in Germany, it has some high-rise buildings in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Language
German (, ) is a West Germanic language in the Indo-European language family, mainly spoken in Western Europe, Western and Central Europe. It is the majority and Official language, official (or co-official) language in Germany, Austria, Switzerland, and Liechtenstein.

Disease
A disease is a particular abnormal condition that adversely affects the structure or function (biology), function of all or part of an organism and is not immediately due to any external injury. Diseases are often known to be medical conditions that are associated with specific signs and symptoms. A disease may be caused by external factors such as pathogens or by internal dysfunctions. For example, internal dysfunctions of the immune system can produce a variety of different diseases, including various forms of immunodeficiency, hypersensitivity, allergy, allergies, and autoimmune disorders. In humans, ''disease'' is often used more broadly to refer to any condition that causes pain, Abnormality (behavior), dysfunction, distress (medicine), distress, social problems, or death to the person affected, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injury in humans, injuries, disability, disabilities, Disorder (medicine) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungus
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tapinella Atrotomentosa
''Tapinella atrotomentosa'', commonly known as the velvet roll-rim or velvet-footed tap, is a species of fungus in the family Tapinellaceae. Although it has gills, it is a member of the pored mushroom order Boletales. August Batsch described the species in 1783. It has been recorded from Eurasia and North America. Tough and inedible, it grows on tree stumps of conifers. The mushroom contains several compounds that act as deterrents of feeding by insects. Taxonomy ''Tapinella atrotomentosa'' was originally described as ''Agaricus atrotomentosus'' by German naturalist August Batsch in his 1783 work ''Elenchus Fungorum'', and given its current name by Josef Šutara in 1992. It is commonly known as the "velvet-footed pax", and the "velvet rollrim". Historical synonyms include ''Paxillus atrotomentosus'' by Elias Magnus Fries (1833), ''Rhymovis atrotomentosa'' by Gottlob Ludwig Rabenhorst (1844), and ''Sarcopaxillus atrotomentosus'' by Ivan Zmitrovich (2004).

Paxillus Involutus
''Paxillus involutus'', also known as the brown roll-rim or the common roll-rim, is a species of basidiomycete fungus. Although it has lamella (mycology), gills, it is more closely related to the pored boletes than to typical gilled mushrooms. It was first described by Jean Baptiste François Pierre Bulliard, Pierre Bulliard in 1785, and was given its current Binomial nomenclature, binomial name by Elias Magnus Fries in 1838. Genetic testing suggests that ''Paxillus involutus'' may be a species complex rather than a single species. Various shades of brown in colour, the basidiocarp, fruit body grows up to high and has a funnel-shaped pileus (mycology), cap up to wide with a distinctive inrolled rim and decurrent gills that may be pore-like close to the stipe (mycology), stipe. The species is widely distributed across the Northern Hemisphere. It has been inadvertently introduced species, introduced to Australia, New Zealand, South Africa, and South America, probably transpor ...

Calocera Cornea
''Calocera cornea'' is a jelly fungus that grows on decaying wood. It is a member of the Dacrymycetales, an order of fungi characterized by their unique "tuning fork" basidia. Its yellow, finger-like, tapering basidiocarps are somewhat gelatinous in texture. In typical specimens the basidiocarps become up to 3 mm in diameter, and 2 cm in height. The hymenium covers the sides of the basidiocarps, each basidium producing and forcibly discharging only two basidiospore A basidiospore is a reproductive spore produced by basidiomycete fungi, a grouping that includes mushrooms, shelf fungi, rusts, and smuts. Basidiospores typically each contain one haploid Ploidy () is the number of complete sets of chromos ...s. It is inedible. '' Calocera viscosa'' is related. References Further reading *C.J.

Clitocybe Nebularis
''Clitocybe nebularis'' or ''Lepista nebularis'', commonly known as the clouded agaric, cloudy clitocybe, or cloud funnel, is an abundant gilled fungus which appears both in conifer-dominated forests and broad-leaved woodland in Europe and North America. Appearing in Britain from mid to late autumn, it is edible, but may cause gastrointestinal issues. Taxonomy The species was first described and named as ''Agaricus nebularis'' in 1789 by August Johann Georg Karl Batsch. It was later placed in the genus '' Clitocybe'' in 1871 by Paul Kummer as ''Clitocybe nebularis''. After much consideration by many mycologists, over some years, when it was placed for periods in both '' Lepista'', and '' Gymnopus'', it was placed back in ''Clitocybe'' with the specific epithet, and 1871 accreditation it retains today. ''Clitocybe nebularis'' var. ''alba'' Bataille (1911), differs only in having a milk white cap, and is very rare. Description The cap of the mushroom is in diameter, convex wi ...

Mushroom
A mushroom or toadstool is the fleshy, spore-bearing Sporocarp (fungi), fruiting body of a fungus, typically produced above ground on soil or another food source. ''Toadstool'' generally refers to a poisonous mushroom. The standard for the name "mushroom" is the cultivated white button mushroom, ''Agaricus bisporus''; hence, the word "mushroom" is most often applied to those fungi (Basidiomycota, Agaricomycetes) that have a stem (Stipe (mycology), stipe), a cap (Pileus (mycology), pileus), and gills (lamellae, sing. Lamella (mycology), lamella) on the underside of the cap. "Mushroom" also describes a variety of other gilled fungi, with or without stems; therefore the term is used to describe the fleshy fruiting bodies of some Ascomycota. The gills produce microscopic Spore#Fungi, spores which help the fungus spread across the ground or its occupant surface. Forms deviating from the standard Morphology (biology), morphology usually have more specific names, such as "bolete", " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmutation Of Species
The Transmutation of species and transformism are 18th and early 19th-century ideas about the change of one species into another that preceded Charles Darwin's theory of evolution through natural selection. The French ''Transformisme'' was a term used by Jean Baptiste Lamarck in 1809 for his theory, and other 18th and 19th century proponents of pre-Darwinian evolutionary ideas included Denis Diderot, Étienne Geoffroy Saint-Hilaire, Erasmus Darwin, Robert Grant, and Robert Chambers, the anonymous author of the 1844 book '' Vestiges of the Natural History of Creation''. Such ideas were associated with 18th century ideas of Deism and human progress. Opposition in the scientific community to these early theories of evolution, led by influential scientists like the anatomists Georges Cuvier and Richard Owen, and the geologist Charles Lyell, was intense. The debate over them was an important stage in the history of evolutionary thought and influenced the subsequent reaction to Dar ...
