The National Fungus Collections of the United States is the "world's largest herbarium of dried fungus specimens".U.S. National Fungus Collections , USDA (last visited Aug. 22, 2012). It is housed within the (USDA). The collection was established in 1869 from a core of fungus collections transferred from the to the USDA. |
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. 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 phenomenon, at least six centuries old, although the techniques have changed l ...

Anna Eliza Jenkins
Anna Eliza Jenkins (10 September 1886 – 26 November 1972) was an American mycologist. She specialized in phytopathology (plant diseases), particularly the fungi responsible for "spot anthracnoses", including '' Sphaceloma'' and '' Elsinoe''. Early life Born on a farm near Walton, New York, Jenkins attended a one-room country school before attending Walton High School, from which she graduated in 1907. Leaving home to study at Cornell University in Ithaca, New York, Jenkins was influenced and encouraged by the prominent mycologists Herbert Hice Whetzel and Louis Melville Massey. She earned her B.Sc. degree in 1911 and her master's degree the year following. A PhD followed later in 1927, after further study at George Washington University and graduate work at Cornell. Career Jenkins started working with the United States Department of Agriculture (USDA) in 1912, and spent most of her career there. Her early research involved the taxonomy and life histories of new of little-kn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Model Organism
A model organism (often shortened to model) is a non-human species that is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the model organism will provide insight into the workings of other organisms. Model organisms are widely used to research human disease when human experimentation would be unfeasible or unethical. This strategy is made possible by the common descent of all living organisms, and the conservation of metabolic and developmental pathways and genetic material over the course of evolution. Studying model organisms can be informative, but care must be taken when generalizing from one organism to another. In researching human disease, model organisms allow for better understanding the disease process without the added risk of harming an actual human. The species chosen will usually meet a determined taxonomic equivalency to humans, so as to react to disease or its treatment in a way that resembles ...

Neurospora
''Neurospora'' is a genus of Ascomycete fungi. The genus name, meaning "nerve spore" refers to the characteristic striations on the spores that resemble axons. The best known species in this genus is ''Neurospora crassa'', a common model organism in biology. ''Neurospora intermedia'' var. ''oncomensis'' is believed to be the only mold belonging to ''Neurospora'' which is used in food production (to make oncom). Characteristics ''Neurospora'' species are molds with broadly spreading colonies, with abundant production of ascomata. Ascomata are superficial or immersed, perithecial and ostiolate or cleistothecial and non-ostiolate, hairy or glabrous, dark coloured. Peridium membranaceous, asci cylindrical, clavate or subspherical, with a persistent or evanescent wall, usually with a thickened and non-amyloid annular structure at the apex, usually 8-spored. Ascospores broadly fusiform, ellipsoidal, or nearly spherical, unicellular, hyaline to yellowish brown or olive-brown, becomin ...

William Webster Diehl
William Webster Diehl (January 15, 1891 – 1978) was an American mycologist recognized for his work on grass pathogens, particularly in the genus ''Balansia''. Diehl was born in on January 15, 1891 in Logansport, Indiana to parents Edwin Randall Diehl and Mary Delilah Wyrick Diehl. The family moved to Ohio shortly after his birth and he attended grammar school in Dayton. He attended Miami University from 1910–1914 and received an MSc in botany from Iowa State College in 1915. He was briefly an instructor of botany and plant pathology with Clemson before joining the USDA where he worked from 1928 until his retirement in 1958. He was honoured in 1954, when '' Diehliomyces'' is a genus of fungi in the Ascomycota phylum, was named after him.

Discomycetes
Discomycetes is a former taxonomic class of Ascomycete fungi which contains all of the cup, sponge and brain fungi and some club-like fungi. It includes typical cup fungi like the scarlet elf cup and the orange peel fungus, and fungi with fruiting bodies of more unusual shape, such as morels, truffles and the swamp beacon. New taxonomic and molecular data fail to support the monophyly of the discomycetes. *A common feature of Discomycetes are the asci, which are typically produced on the surface of cup-like fruiting bodies. In most discomycetes, each ascus contains eight sexual spores that are forcibly discharged into the air when mature. *In modern classifications, the members of the obsolete class are included in Pezizomycetes, Lecanoromycetes, Leotiomycetes and Sordariomycetes.

Edith K
Edith is a feminine given name derived from the Old English words ēad, meaning 'riches or blessed', and is in common usage in this form in English, German, many Scandinavian languages and Dutch. Its French form is Édith. Contractions and variations of this name include Ditte, Dita, and Edie. It was a common first name prior to the 16th century, when it fell out of favour. It became popular again at the beginning of the 19th century, and in 2016 it was ranked at 488th most popular female name in the United States, according to the Social Security online database. It became far less common as a name for children by the late 20th century.

Plant Quarantine Act Of 1912
The Plant Quarantine Act, originally enacted in 1912 (7 U.S.C. 151 et seq.), gave the Animal and Plant Health Inspection Service (APHIS) authority to regulate the importation and interstate movement of nursery stock and other plants that may carry pests and diseases that are harmful to agriculture. This Act has been superseded by the consolidated APHIS statute, the Plant Protection Act of 2000 (7 U.S.C. 7701 et seq.). This authority is particularly important to the agency’s ability to prevent or limit the spread of harmful invasive species within or to a state or region of the United States. Provisions of Act The Plant Quarantine Act was codified as fifteen sections formulating regulations and rules for the importation of nursery stock including annual plants and biennial plants A biennial plant is a flowering plant that, generally in a temperate climate, takes two years to complete its biological life cycle. Life cycle In its first year, the biennal plant undergoes primary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
