Josef Herink
Josef Herink (26 December 1915 – 20 August 1999) was a Czech physician and mycologist. Life and career Josef Herink was born in Prague on 26 December 1915. He completed his medical studies at Charles University in Prague before practicing as a specialist in internal medicine in Turnov and Mnichovo Hradiště, in northern Bohemia. Very active in mycology, he was one of the initiators, in 1945, of the Czechoslovak Mycological Club , founded the following year, and renamed since 1993 the Czech Scientific Society for Mycology. From 1947 to his last months he was actively involved in the scientific journal called ''Czech Mycology'' (formerly ''Česká mykologie''), of which he is one of the founders. He wrote numerous biographical notes on Czech mycologists. Most of his mycological and biographical contributions are published in the Czech language. He devoted much of his career as a mycologist to the study of his favourite genus, ''Lepiota'', but he also worked on the genera ''Ag ...

Prague
Prague ( ; cs, Praha ; german: Prag, ; la, Praga) is the capital and largest city in the Czech Republic, and the historical capital of Bohemia. On the Vltava river, Prague is home to about 1.3 million people. The city has a temperate oceanic climate, with relatively warm summers and chilly winters. Prague is a political, cultural, and economic hub of central Europe, with a rich history and Romanesque, Gothic, Renaissance and Baroque architectures. It was the capital of the Kingdom of Bohemia and residence of several Holy Roman Emperors, most notably Charles IV (r. 1346–1378). It was an important city to the Habsburg monarchy and Austro-Hungarian Empire. The city played major roles in the Bohemian and the Protestant Reformations, the Thirty Years' War and in 20th-century history as the capital of Czechoslovakia between the World Wars and the post-war Communist era. Prague is home to a number of well-known cultural attractions, many of which survived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Omphalina
''Omphalina'' is a genus of small agarics with white, nonamyloid, basidiospores and decurrent gills. Typically the cap has a deep central depression giving the umbrella-like to funnel-shaped cap the appearance of a belly button, or a belly with a navel. Similarly-shaped agarics are said to be omphalinoid in appearance. Etymology ''Omphalina'' is the diminutive of ''Omphalia'' which is a reference to the belly button or navel-like appearance of the small dome-shaped caps with a central depression. It derives from the Greek word omphalos. Historical nomenclatural confusion The generic name ''Omphalina'' is an ancient one, linked to the even older mushroom name ''Omphalia'' which cannot be used because it is an illegitimate later homonym. Historically, the former was generally applied to any white-spored, similarly sized and shaped mushroom. As a result, many species that still are labeled ''Omphalina'', or were labeled ''Omphalia'' are in fact not true Omphalinas. The now conserve ...

Clitocybe
''Clitocybe'' is a genus of mushrooms characterized by white, off-white, buff, cream, pink, or light-yellow spores, gills running down the stem, and pale white to brown or lilac coloration. They are primarily saprotrophic, decomposing forest ground litter. There are estimated to be around 300 species in the widespread genus. ''Clitocybe'' means ''sloping head''. A few members of the genus are considered edible; many others are poisonous, containing the toxin muscarine among others. Distinguishing individual species of ''Clitocybe'' is generally prohibitively difficult to non-experts, requiring the analysis of microscopic characters. Therefore, with the exception of a few charismatic and readily identified members, ''Clitocybe'' mushrooms are rarely collected for consumption. Taxonomy ''Clitocybe'' was originally proposed by Elias Fries in 1821 as a tribe in the genus ''Agaricus''. Friedrich Staude elevated it to generic status in 1857. Recent molecular work has shown the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slovakia
Slovakia (; sk, Slovensko ), officially the Slovak Republic ( sk, Slovenská republika, links=no ), is a landlocked country in Central Europe. It is bordered by Poland to the north, Ukraine to the east, Hungary to the south, Austria to the southwest, and the Czech Republic to the northwest. Slovakia's mostly mountainous territory spans about , with a population of over 5.4 million. The capital and largest city is Bratislava, while the second largest city is Košice. The Slavs arrived in the territory of present-day Slovakia in the fifth and sixth centuries. In the seventh century, they played a significant role in the creation of Samo's Empire. In the ninth century, they established the Principality of Nitra, which was later conquered by the Principality of Moravia to establish Great Moravia. In the 10th century, after the dissolution of Great Moravia, the territory was integrated into the Principality of Hungary, which then became the Kingdom of Hungary in 1000. In 124 ...

Cryptogam
A cryptogam (scientific name Cryptogamae) is a plant (in the wide sense of the word) or a plant-like organism that reproduces by spores, without flowers or seeds. The name ''Cryptogamae'' () means "hidden reproduction", referring to the fact that no seed is produced, thus cryptogams represent the non-seed bearing plants. Other names, such as "thallophytes", " lower plants", and "spore plants" are also occasionally used. As a group, Cryptogamae are the opposite of the Phanerogamae () or Spermatophyta (), the seed plants. The best-known groups of cryptogams are algae, lichens, mosses, and ferns, but it also includes non-photosynthetic organisms traditionally classified as plants, such as fungi, slime molds, and bacteria. The classification is now deprecated in Linnaean taxonomy. At one time, the cryptogams were formally recognised as a group within the plant kingdom. In his system for classification of all known plants and animals, Carl Linnaeus (1707–1778) divided the plant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nature Reserve
A nature reserve (also known as a wildlife refuge, wildlife sanctuary, biosphere reserve or bioreserve, natural or nature preserve, or nature conservation area) is a protected area of importance for flora, fauna, or features of geological or other special interest, which is reserved and managed for purposes of conservation and to provide special opportunities for study or research. They may be designated by government institutions in some countries, or by private landowners, such as charities and research institutions. Nature reserves fall into different IUCN categories depending on the level of protection afforded by local laws. Normally it is more strictly protected than a nature park. Various jurisdictions may use other terminology, such as ecological protection area or private protected area in legislation and in official titles of the reserves. History Cultural practices that roughly equate to the establishment and maintenance of reserved areas for animals date b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nature Conservation
Nature conservation is the moral philosophy and conservation movement focused on protecting species from extinction, maintaining and restoring habitats, enhancing ecosystem services, and protecting biological diversity. A range of values underlie conservation, which can be guided by biocentrism, anthropocentrism, ecocentrism, and sentientism, environmental ideologies that inform ecocultural practices and identities. There has recently been a movement towards evidence-based conservation which calls for greater use of scientific evidence to improve the effectiveness of conservation efforts. As of 2018 15% of land and 7.3% of the oceans were protected. Many environmentalists set a target of protecting 30% of land and marine territory by 2030. In 2021, 16.64% of land and 7.9% of the oceans were protected. The 2022 IPCC report on climate impacts and adaptation, underlines the need to conserve 30% to 50% of the Earth's land, freshwater and ocean areas – echoing the 30% goal of t ...

National Museum (Prague)
The National Museum (NM) (Czech: ''Národní muzeum'') is a Czech museum institution intended to systematically establish, prepare, and publicly exhibit natural scientific and historical collections. It was founded in 1818 by Kašpar Maria Šternberg. Historian František Palacký was also strongly involved in the foundation of the museum. The National Museum houses nearly 14 million items from the areas of natural history, history, arts, music and librarianship, which are located in dozens of museum buildings. The main building of the National Museum has been renovated in 2011–2019, and permanent exhibitions are gradually being opened from Spring 2020. Origins After the French Revolution, royal and private collections of art, science and culture were made available to the public. The beginnings of the museum can be seen as far back as 1796 when the private Society of Patriotic Friends of the Arts was founded by Count Casper Sternberk-Manderschied and a group of other prominen ...

Herbarium
A herbarium (plural: herbaria) is a collection of preserved plant specimens and associated data used for scientific study. The specimens may be whole plants or plant parts; these will usually be in dried form mounted on a sheet of paper (called '' exsiccatum'', plur. ''exsiccata'') but, depending upon the material, may also be stored in boxes or kept in alcohol or other preservative. The specimens in a herbarium are often used as reference material in describing plant taxa; some specimens may be types, some may be specimens distributed in series called exsiccatae. The same term is often used in mycology to describe an equivalent collection of preserved fungi, otherwise known as a fungarium. A xylarium is a herbarium specialising in specimens of wood. The term hortorium (as in the Liberty Hyde Bailey Hortorium) has occasionally been applied to a herbarium specialising in preserving material of horticultural origin. History The making of herbaria is an ancient phenome ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microscopy
Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye). There are three well-known branches of microscopy: optical, electron, and scanning probe microscopy, along with the emerging field of X-ray microscopy. Optical microscopy and electron microscopy involve the diffraction, reflection, or refraction of electromagnetic radiation/electron beams interacting with the specimen, and the collection of the scattered radiation or another signal in order to create an image. This process may be carried out by wide-field irradiation of the sample (for example standard light microscopy and transmission electron microscopy) or by scanning a fine beam over the sample (for example confocal laser scanning microscopy and scanning electron microscopy). Scanning probe microscopy involves the interaction of a scanning probe with the surface of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lactarius (fungus)
''Lactarius'' is a genus of mushroom-producing, ectomycorrhizal fungi, containing several edible species. The species of the genus, commonly known as milk-caps, are characterized by the milky fluid ("latex") they exude when cut or damaged. Like the closely related genus ''Russula'', their flesh has a distinctive brittle consistency. It is a large genus with over 500 known species, mainly distributed in the Northern hemisphere. Recently, the genus '' Lactifluus'' has been separated from ''Lactarius'' based on molecular phylogenetic evidence. Systematics and taxonomy The genus ''Lactarius'' was described by Christian Hendrik Persoon in 1797 with '' L. piperatus'' as the original type species. In 2011, '' L. torminosus'' was accepted as the new type of the genus after the splitting-off of ''Lactifluus'' as separate genus. The name "''Lactarius''" is derived from the Latin '' lac'', "milk". Placement within Russulaceae Molecular phylogenetics uncovered that, while macromorpholo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bolete
{{refimprove, date=July 2020 A bolete is a type of mushroom, or fungal fruiting body. It can be identified thanks to a unique mushroom cap. The cap is clearly different from the stem. On the underside of the cap there is usually a spongy surface with pores, instead of the gills typical of mushrooms. However, there are some boletes that are gilled, such as species of '' Chroogomphus'', '' Gomphidius'', ''Paxillus'', '' Phylloporus'' and '' Hygrophoropsis aurantiaca''. "Bolete" is the English common name In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrast ... for fungus species whose mushroom caps have this appearance. The boletes are classified in the order Boletales. Not all members of the order Boletales are boletes. The micromorphology and molecular phylogeny of the order ...
