John Axel Nannfeldt
John-Axel Nannfeldt (baptized ''Johan Axel Frithiof Nannfeldt''), born 18 January 1904 in Trelleborg and deceased 4 November 1985 in Uppsala, was a Swedish botanist and mycologist. Nannfeldt studied natural history at the University of Uppsala and obtained a doctorate degree in 1932. He became professor of botany at Uppsala University in 1939, a position he held until his retirement in 1970. He did numerous studies on the systematics of fungi and vascular plants. Among the groups he treated were the plant pathogenic rust fungi, smut fungi and '' Exobasidium''. He also treated taxonomy and biogeography of various groups of vascular plants, e.g. the arctic ''Poa laxa'' complex. Nannfeldt published the exsiccate work ''Fungi Exsiccati Suecici, praesertim Upsalienses'' together with Lennart Holm and others. He was elected member no. 983 of the Royal Swedish Academy of Sciences in 1955. The fungal genus ''Nannfeldtiella'' was named in his honour by Franz Petrak in 1947 ...

Trelleborg
Trelleborg () is a town in Skåne County, Sweden, with 43,359 inhabitants as of December 31, 2015. It is the southernmost town in Sweden located some west from the southernmost point of Sweden and the Scandinavian peninsula. It is one of the most important ferry towns in Scandinavia as well as around the Baltic Sea, and the main town of the Söderslätt agricultural areas. Etymology The first written record of the name is from 1257, ''Threlæburgh''. The name is found in many places in Scandinavia. ''Borg'' means ''castle'' or ''stronghold'' and ''träl'' can mean thrall, but can also refer to the leaning poles on the outside of the medieval Viking stronghold. Remains of the original stronghold were excavated in 1988. The name may also have originated from the stronghold that still remains in the center of the city. Strongholds like that have been found at several places around Scandinavia, mostly in the south of Sweden and Denmark, and are all called trelleborgs. The name is ...

Biogeography
Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area.Brown University, "Biogeography." Accessed February 24, 2014. . Phytogeography is the branch of biogeography that studies the distribution of plants. Zoogeography is the branch that studies distribution of animals. Mycogeography is the branch that studies distribution of fungi, such as mushrooms. Knowledge of spatial variation in the numbers and types of organisms is as vital to us today as it was to our early human ancestors, as we adapt to heterogeneous but geographically predictable environments. Biogeography is an integrative field of inquiry that unites concepts and information from ecology, evolutionary biology, taxonomy, geology, physical geography, palaeontology, and climatology.Dansereau, ...

Plectania Nannfeldtii
''Plectania nannfeldtii'', commonly known as Nannfeldt's Plectania, the black felt cup, or the black snowbank cup fungus, is a species of fungus in the family Sarcosomataceae. The fruit bodies of this species resemble small, black, goblet-shaped shallow cups up to wide, with stems up to long attached to black mycelia. Fruit bodies, which may appear alone or in groups on the ground in conifer duff, are usually attached to buried woody debris, and are commonly associated with melting snow. ''Plectania nannfeldtii'' is found in western North America and in Asia, often at higher elevations. Similar black cup fungi with which ''P. nannfeldtii'' may be confused include '' Pseudoplectania vogesiaca'', '' P. nigrella'', and ''Helvella corium''. Taxonomy The species was first described by British mycologist Fred Jay Seaver in 1928, who called it ''Paxina nigrella'' in his monograph of the cup fungi of North America. The type specimens were found in 1914 in Tolland, Colora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cup Fungus
The Pezizaceae (commonly referred to as cup fungi) are a family of fungi in the Ascomycota which produce mushrooms that tend to grow in the shape of a "cup". Spores are formed on the inner surface of the fruit body (mushroom). The cup shape typically serves to focus raindrops into splashing spores out of the cup. Additionally, the curvature enables wind currents to blow the spores out in a different manner than in most agarics and boletes. Cup fungi grow in peculiar shapes, frequently resembling cups or saucers. For example, the orange peel fungus ('' Aleuria aurantia'') resembles a discarded orange rind. They may be vividly colored, like the scarlet cup (''Sarcoscypha coccinea''), which is often one of the first signs of spring where it grows. According to one 2008 estimate, the family contains 31 genera and 230 species. Subtaxa Pezizaceae includes the following: *'' Adelphella'' **'' Adelphella babingtonii'' *''Amylascus'' **''Amylascus tasmanicus'' *''Aquapeziza' ...

Pyronemataceae
The Pyronemataceae are a family of fungi in the order Pezizales. It is the largest family of the Pezizales, encompassing 75 genera and approximately 500 species. Phylogenetic analyses does not support the prior classifications of this family, and suggest that the family is not monophyletic as it is currently circumscribed. Morphology Members of the family are diverse in ascomatal or cleistothecial form. Individual taxa may be sessile (without a stipe) to shortly stipitate, cupulate (cup-shaped), discoid (disc-shaped), pulvinate (cushion-shaped), or with turbinate (turban-shaped) epigeous apothecia. Also, taxa may be sub-hypogeous to hypogeous with closed, folded, or solid ascomata. Apothecia may range in size from less than 1 mm up to 12 cm in diameter, and may be brightly colored due to carotenoid pigments. Genera of the Pyronemataceae lack unifying macroscopic or microscopic characteristics; this lack of uniting characters has led various authors to propose a variety ...

Richard Korf
Richard Paul "Dick" Korf (May 28, 1925 – August 20, 2016) was an American mycologist and founding co-editor of the journal ''Mycotaxon''. He was a preeminent figure in the study of discomycetes and made significant contributions to the field of fungal nomenclature and taxonomy. Korf was professor emeritus of mycology at Cornell University and director emeritus of Cornell University's Plant Pathology Herbarium. Early life and education Korf was born on May 28, 1925, to an upper-middle-class family with homes in Westchester County, New York, and New Fairfield, Connecticut. While attending the prestigious Riverdale Country School in New York City, Korf was placed in charge of his biology class after their teacher joined the military. "In retrospect," Korf wrote, "I am convinced that this experience had an enormous impact on my future and on my decision to enter the teaching profession." In 1942, shortly after his 17th birthday, Korf enrolled at Cornell University "with the vagu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Synonym
A synonym is a word, morpheme, or phrase that means exactly or nearly the same as another word, morpheme, or phrase in a given language. For example, in the English language, the words ''begin'', ''start'', ''commence'', and ''initiate'' are all synonyms of one another: they are ''synonymous''. The standard test for synonymy is substitution: one form can be replaced by another in a sentence without changing its meaning. Words are considered synonymous in only one particular sense: for example, ''long'' and ''extended'' in the context ''long time'' or ''extended time'' are synonymous, but ''long'' cannot be used in the phrase ''extended family''. Synonyms with exactly the same meaning share a seme or denotational sememe, whereas those with inexactly similar meanings share a broader denotational or connotational sememe and thus overlap within a semantic field. The former are sometimes called cognitive synonyms and the latter, near-synonyms, plesionyms or poecilonyms. Lexicogr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...
