Calvatia Sculpta
''Calvatia sculpta'', commonly known as the sculpted puffball, the sculptured puffball, the pyramid puffball, and the Sierran puffball, is a species of puffball fungus in the family Agaricaceae. Attaining dimensions of up to tall by wide, the pear- or egg-shaped puffball is readily recognizable because of the large pyramidal or polygonal warts covering its surface. It is edible when young, before the spores inside the fruit body disintegrate into a brownish powder. The spores are roughly spherical, and have wart-like projections on their surfaces. Originally described from the Sierra Nevada, ''C. sculpta'' is found in mountainous areas in western North America, and was found in a Brazilian dune in 2008. It may be easily confused with ''Calbovista subsculpta'', a similar puffball that—in addition to differences observable only with a microscope—is larger, and has slightly raised warts with a felt-like texture. Other similar species include '' Calvatia arctica'' and i ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Harvey Willson Harkness
Harvey Willson Harkness (May 25, 1821 – July 10, 1901) was an American mycologist and natural historian best known for his early descriptions of California fungal species. Born and raised in Massachusetts and trained as a physician, Harkness came to California during the Gold Rush in 1849. He first set up a medical practice in the mining camp at Bidwell's Bar but moved to Sacramento in 1851. He rose to prominence as physician, educator, real estate developer, and newspaper editor in Sacramento, becoming part of the social circle of early California notables such as Leland Stanford, Charles Crocker, Collis Huntington, and Mark Hopkins. His active interest in school education led to his election as the first president of the Sacramento board of education in 1853. Harkness was a participant in the ceremony in May 1869 that marked the completion of the First transcontinental railroad, representing California and bearing the Golden Spike that was driven in by Leland Stanford ma ...

1906 San Francisco Earthquake
At 05:12 Pacific Standard Time on Wednesday, April 18, 1906, the coast of Northern California was struck by a major earthquake with an estimated moment magnitude of 7.9 and a maximum Mercalli intensity of XI (''Extreme''). High-intensity shaking was felt from Eureka on the North Coast to the Salinas Valley, an agricultural region to the south of the San Francisco Bay Area. Devastating fires soon broke out in San Francisco and lasted for several days. More than 3,000 people died, and over 80% of the city was destroyed. The events are remembered as one of the worst and deadliest earthquakes in the history of the United States. The death toll remains the greatest loss of life from a natural disaster in California's history and high on the lists of American disasters. Tectonic setting The San Andreas Fault is a continental transform fault that forms part of the tectonic boundary between the Pacific Plate and the North American Plate. The strike-slip fault is characterized by ma ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Micrometre
The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix "micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . The longest human chromosome, chromosome 1, is approximately in length. Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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 nucleus that is the product of meiosis, and they are produced by specialized fungal cells called basidia. Typically, four basidiospores develop on appendages from each basidium, of which two are of one strain and the other two of its opposite strain. In gills under a cap of one common species, there exist millions of basidia. Some gilled mushrooms in the order Agaricales have the ability to release billions of spores. The puffball fungus ''Calvatia gigantea'' has been calculated to produce about five trillion basidiospores. Most basidiospores are forcibly discharged, and are thus considered ballistospores. These spores serve as the main air dispersal units for the fungi. The spores are released during periods of high humidity and generally have a night-time or pre-dawn peak concentration in the ...

Peridium
The peridium is the protective layer that encloses a mass of spores in fungi. This outer covering is a distinctive feature of gasteroid fungi. Description Depending on the species, the peridium may vary from being paper-thin to thick and rubbery or even hard. Typically, peridia consist of one to three layers. If there is only a single layer, it is called a peridium. If two layers are present, the outer layer is called the exoperidium and the inner layer the endoperidium. If three layers are present, they are the exoperidium, the mesoperidium and the endoperidium. In the simplest subterranean forms, the peridium remains closed until the spores are mature, and even then shows no special arrangement for dehiscence or opening, but has to decay before the spores are liberated. Puffballs For most fungi, the peridium is ornamented with scales or spines. In species that become raised above ground during their development, generally known as the "puffballs", the peridium is usually di ...

Sporocarp (fungus)
The sporocarp (also known as fruiting body, fruit body or fruitbody) of fungi is a multicellular structure on which spore-producing structures, such as basidia or asci, are borne. The fruitbody is part of the sexual phase of a fungal life cycle, while the rest of the life cycle is characterized by vegetative mycelial growth and asexual spore production. The sporocarp of a basidiomycete is known as a ''basidiocarp'' or ''basidiome'', while the fruitbody of an ascomycete is known as an ''ascocarp''. Many shapes and morphologies are found in both basidiocarps and ascocarps; these features play an important role in the identification and taxonomy of fungi. Fruitbodies are termed ''epigeous'' if they grow on the ground, while those that grow underground are ''hypogeous''. Epigeous sporocarps that are visible to the naked eye, especially fruitbodies of a more or less agaricoid morphology, are often called mushrooms. Epigeous sporocarps have mycelia that extend underground far be ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Calvatia Sculpta 47702
''Calvatia'' is a genus of puffball mushrooms that includes the spectacular giant puffball ''C. gigantea''. It was formerly classified within the now-obsolete order Lycoperdales, which, following a restructuring of fungal taxonomy brought about by molecular phylogeny, has been split; the puffballs, ''Calvatia spp.'' are now placed in the family Agaricaceae of the order Agaricales. Most species in the genus ''Calvatia'' are edible when young, though some are best avoided, such as '' Calvatia fumosa'', which has a very pungent odor. The name ''Calvatia'' derives from the Latin ''calvus'' meaning "bald" and ''calvaria'', meaning "dome of the skull". Taxonomy ''Calvatia'' was circumscribed by Swedish mycologist Elias Magnus Fries in 1849. Fries included a single species in the genus, '' Calvatia craniiformis'', which was originally described as ''Bovista craniiformis'' by Lewis David de Schweinitz in 1832. Species , Index Fungorum lists 58 species of ''Calvatia''. * ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Section (biology)
In biology a section ( la, sectio) is a taxonomic rank that is applied differently in botany and zoology. In botany Within flora (plants), 'section' refers to a ''botanical'' rank below the genus, but above the species: * Domain > Kingdom > Division > Class > Order > Family > Tribe > Genus > Subgenus > Section > Subsection > Species In zoology Within fauna (animals), 'section' refers to a ''zoological'' rank below the order, but above the family: * Domain > Kingdom > Phylum > Class > Order > Section > Family > Tribe > Genus > Species In bacteriology The International Code of Nomenclature for Bacteria The International Code of Nomenclature of Prokaryotes (ICNP) formerly the International Code of Nomenclature of Bacteria (ICNB) or Bacteriological Code (BC) governs the scientific names for Bacteria and Archaea.P.

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 contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested par ...
