Galiella Japonica
''Galiella'' is a genus of fungi in the family Sarcosomataceae. The genus is widely distributed in northern temperate regions, and according to one estimate, contains eight species. Taxonomy ''Galiella'' was described in 1957 by Richard Korf and John Axel Nannfeldt. In the early 1950s, French mycologist Marcelle Louise Fernande Le Gal used the generic name ''Sarcosoma'' to treat several species that she did not think belonged in the same genus as ''Sarcosoma globosum'', the type species. As Korf later pointed out, this usage contravened the rules of botanical nomenclature. Korf and Nannfield proposed ''Galiella'' to accommodate these species, and set '' G. rufa'' as the type. The generic name honors French mycologist Marcelle Louise Fernande Le Gal. Description ''Galiella'' includes bulgarioid species (those with a morphology similar to those in ''Bulgaria'') with spores featuring surface warts that are made of callose-pectic substances that stain with methyl blue Met ...

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, (now ...

Callose
Callose is a plant polysaccharide. Its production is due to the glucan synthase-like gene (GLS) in various places within a plant. It is produced to act as a temporary cell wall in response to stimuli such as stress or damage. Callose is composed of glucose residues linked together through β-1,3-linkages, and is termed a β-glucan. It is thought to be manufactured at the cell wall by callose synthases and is degraded by β-1,3-glucanases. Callose is very important for the permeability of plasmodesmata (Pd) in plants; the plant's permeability is regulated by plasmodesmata callose (PDC). PDC is made by callose synthases and broken down by β-1,3-glucanases (BGs). The amount of callose that is built up at the plasmodesmatal neck, which is brought about by the interference of callose synthases (CalSs) and β-1,3-glucanases, determines the conductivity of the plasmodesmata. Formation and function Callose is laid down at plasmodesmata, at the cell plate during cytokinesis, and during po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By John Axel Nannfeldt
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pezizales Genera
The Pezizales are an order of the subphylum Pezizomycotina within the phylum Ascomycota. The order contains 16 families, 199 genera, and 1683 species. It contains a number of species of economic importance, such as morels, the black and white truffles, and the desert truffles. The Pezizales can be saprobic, mycorrhizal, or parasitic on plants. Species grow on soil, wood, leaves and dung. Soil-inhabiting species often fruit in habitats with a high pH and low content of organic matter, including disturbed ground. Most species occur in temperate regions or at high elevation. Several members of the Sarcoscyphaceae and Sarcosomataceae are common in tropical regions. Description Members of this order are characterized by asci that typically open by rupturing to form a terminal or eccentric lid or operculum. The ascomata are apothecia or are closed structures of various forms derived from apothecia. Apothecia range in size from less than a millimeter to approximately 15 cm ...

Galiella Thwaitesii
''Galiella'' is a genus of fungi in the family Sarcosomataceae. The genus is widely distributed in northern temperate regions, and according to one estimate, contains eight species. Taxonomy ''Galiella'' was described in 1957 by Richard Korf and John Axel Nannfeldt. In the early 1950s, French mycologist Marcelle Louise Fernande Le Gal used the generic name ''Sarcosoma'' to treat several species that she did not think belonged in the same genus as ''Sarcosoma globosum'', the type species. As Korf later pointed out, this usage contravened the rules of botanical nomenclature. Korf and Nannfield proposed ''Galiella'' to accommodate these species, and set '' G. rufa'' as the type. The generic name honors French mycologist Marcelle Louise Fernande Le Gal.

Methyl Blue
Methyl blue is a chemical compound with the molecular formula C37H27N3Na2O9S3. It is used as a stain in histology, and stains collagen blue in tissue sections. It can be used in some differential staining techniques such as Mallory's connective tissue stain and Gömöri trichrome stain, and can be used to mediate electron transfer in microbial fuel cells. Fungal cell walls are also stained by methyl blue. Methyl blue is also available in mixture with water blue, under name Aniline Blue WS, Aniline blue, China blue, or Soluble blue; and in a solution of phenol, glycerol, and lactic acid under the name Lactophenol cotton blue (LPCB), which is used for microscopic visualization of fungi.
