Mycena Pura
''Mycena pura'', commonly known as the lilac bonnet, is a species of mushroom in the family Mycenaceae. First called ''Agaricus prunus'' in 1794 by Christian Hendrik Persoon, it was assigned its current name in 1871 by German Paul Kummer. ''Mycena pura'' is known to bioaccumulate the element boron. Description The cap ranges from . The stalk is tall and 3–7 mm wide. The spores are white. Similar species include ''Clitocybe nuda'', ''Laccaria amethysteo-occidentalis'', and '' Mycena purpureofusca''. Bioactive compounds ''Mycena pura'' contains the chemical puraquinonic acid, a sesquiterpene. This compound induces mammalian cells (specifically, the cell line HL60) to differentiate into granulocyte- or macrophage-like cells. The fungus also contains the mycotoxin muscarine, and the antifungal metabolite strobilurin D, the latter previously found in '' Cyphellopsis anomala''. Despite the presence of these toxins, some guides list ''M. pura'' as edible. Gallery ...

Christian Hendrik Persoon
Christiaan Hendrik Persoon (1 February 1761 – 16 November 1836) was a German mycologist who made additions to Linnaeus' mushroom taxonomy. Early life Persoon was born in South Africa at the Cape of Good Hope, the third child of an immigrant Pomeranian father and Dutch mother. His mother died soon after he was born; at the age of thirteen his father (who died a year later) sent him to Europe for his education. Education Initially studying theology at Halle, at age 22 (in 1784) Persoon switched to medicine at Leiden and Göttingen. He received a doctorate from the "Kaiserlich-Leopoldinisch-Carolinische Deutsche Akademie der Naturforscher" in 1799. Later years He moved to Paris in 1802, where he spent the rest of his life, renting an upper floor of a house in a poor part of town. He was apparently unemployed, unmarried, poverty-stricken and a recluse, although he corresponded with botanists throughout Europe. Because of his financial difficulties, Persoon agreed to do ...

Granulocyte
Granulocytes are cells in the innate immune system characterized by the presence of specific granules in their cytoplasm. Such granules distinguish them from the various agranulocytes. All myeloblastic granulocytes are polymorphonuclear. They have varying shapes (morphology) of the nucleus (segmented, irregular; often lobed into three segments); and are referred to as polymorphonuclear leukocytes (PMN, PML, or PMNL). In common terms, ''polymorphonuclear granulocyte'' refers specifically to "neutrophil granulocytes", the most abundant of the granulocytes; the other types (eosinophils, basophils, and mast cells) have varying morphology. Granulocytes are produced via granulopoiesis in the bone marrow. Types There are four types of granulocytes (full name polymorphonuclear granulocytes): * Basophils * Eosinophils * Neutrophils * Mast cells Except for the mast cells, their names are derived from their staining characteristics; for example, the most abundant granulocyte is the neut ...

Mycena
''Mycena'' is a large genus of small saprotrophic mushrooms that are rarely more than a few centimeters in width. They are characterized by a white spore print, a small conical or bell-shaped cap, and a thin fragile stem. Most are gray or brown, but a few species have brighter colors. Most have a translucent and striate cap, which rarely has an incurved margin. The gills are attached and usually have cystidia. Some species, like ''Mycena haematopus'', exude a latex when the stem is broken, and many species have a chlorine or radish-like odor. Overview ''Mycenas'' are hard to identify to species and some are distinguishable only by microscopic features such as the shape of the cystidia. Some species are edible, while others contain toxins, but the edibility of most is not known, as they are likely too small to be useful in cooking. ''Mycena pura'' contains the mycotoxin muscarine, but the medical significance of this is unknown. Over 58 species are known to be bioluminescent, ...

Bioluminescent Fungi
Bioluminescence is the production and emission of light by living organisms. It is a form of chemiluminescence. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria, and terrestrial arthropods such as fireflies. In some animals, the light is bacteriogenic, produced by symbiotic bacteria such as those from the genus ''Vibrio''; in others, it is autogenic, produced by the animals themselves. In a general sense, the principal chemical reaction in bioluminescence involves a light-emitting molecule and an enzyme, generally called luciferin and luciferase, respectively. Because these are generic names, luciferins and luciferases are often distinguished by the species or group, e.g. firefly luciferin. In all characterized cases, the enzyme catalyzes the oxidation of the luciferin. In some species, the luciferase requires other cofactors, such as calcium or magnesium ions, and sometime ...

List Of Bioluminescent Fungus Species
] Found largely in temperate and tropical climates, currently there are more than 112 known species of bioluminescent fungi, all of which are members of the order Agaricales (Basidiomycota) with one exceptional ascomycete belonging to the order Xylariales. All known bioluminescent Agaricales are mushroom-forming, white-spored agarics that belong to four distinct evolutionary lineages. The Omphalotus lineage (comprising the genera ''Omphalotus'' and ''Neonothopanus'') contains 12 species, the ''Armillaria'' lineage has 10 known species, while the Mycenoid lineage ('' Favolachia, Mycena'', ''Panellus'', '' Prunulus'', '' Roridomyces'') has more than 50 species. The recently discovered Lucentipes lineage contains two species, ''Mycena lucentipes'' and '' Gerronema viridilucens'', which belong to a family that has not yet been formally named. ''Armillaria mellea'' is the most widely distributed of the luminescent fungi, found across Asia, Europe, North America, and South Africa. Biol ...

Edible Mushroom
Edible mushrooms are the fleshy and edible fruit bodies of several species of macrofungi (fungi which bear fruiting structures that are large enough to be seen with the naked eye). They can appear either below ground (hypogeous) or above ground (epigeous) where they may be picked by hand. Edibility may be defined by criteria that include absence of poisonous effects on humans and desirable taste and aroma. Edible mushrooms are consumed for their nutritional and culinary value. Mushrooms, especially dried shiitake, are sources of umami flavor. Edible mushrooms include many fungal species that are either harvested wild or cultivated. Easily cultivated and common wild mushrooms are often available in markets, and those that are more difficult to obtain (such as the prized truffle, matsutake, and morel) may be collected on a smaller scale by private gatherers. Some preparations may render certain poisonous mushrooms fit for consumption. Before assuming that any wild mushroom is ...

Strobilurin
Strobilurins are a group of natural products and their synthetic analogs. A number of strobilurins are used in agriculture as fungicides. They are part of the larger group of QIs (Quinone outside Inhibitors), which act to inhibit the respiratory chain at the level of Complex III. The first parent natural products, strobilurins A and B, were extracted from the fungus ''Strobilurus tenacellus''. Commercial strobilurin fungicides were developed through optimization of photostability and activity. Strobilurins represented a major development in fungus-based fungicides. First released in 1996, there are now ten major strobilurin fungicides on the market, which account for 23-25 % of the global fungicide sales. Examples of commercialized strobilurin derivatives are azoxystrobin, kresoxim-methyl, picoxystrobin, fluoxastrobin, oryzastrobin, dimoxystrobin, pyraclostrobin and trifloxystrobin. Strobilurins are mostly contact fungicides with a long half time as they are absorbed into the ...

Fungicide
Fungicides are biocidal chemical compounds or biological organisms used to kill parasitic fungi or their spores. A fungistatic inhibits their growth. Fungi can cause serious damage in agriculture, resulting in critical losses of yield, quality, and profit. Fungicides are used both in agriculture and to fight fungal infections in animals. Chemicals used to control oomycetes, which are not fungi, are also referred to as fungicides, as oomycetes use the same mechanisms as fungi to infect plants. Fungicides can either be contact, translaminar or systemic. Contact fungicides are not taken up into the plant tissue and protect only the plant where the spray is deposited. Translaminar fungicides redistribute the fungicide from the upper, sprayed leaf surface to the lower, unsprayed surface. Systemic fungicides are taken up and redistributed through the xylem vessels. Few fungicides move to all parts of a plant. Some are locally systemic, and some move upwardly. Most fungicides that can ...

Muscarine
Muscarine, L-(+)-muscarine, or muscarin is a natural product found in certain mushrooms, particularly in ''Inocybe'' and ''Clitocybe'' species, such as the deadly '' C. dealbata''. Mushrooms in the genera ''Entoloma'' and ''Mycena'' have also been found to contain levels of muscarine which can be dangerous if ingested. Muscarine has been found in harmless trace amounts in ''Boletus'', ''Hygrocybe'', ''Lactarius'' and ''Russula''. Trace concentrations of muscarine are also found in ''Amanita muscaria'', though the pharmacologically more relevant compound from this mushroom is the Z-drug-like alkaloid muscimol. ''A. muscaria'' fruitbodies contain a variable dose of muscarine, usually around 0.0003% fresh weight. This is very low and toxicity symptoms occur very rarely. ''Inocybe'' and ''Clitocybe'' contain muscarine concentrations up to 1.6%. Muscarine is a nonselective agonist of the muscarinic acetylcholine receptors. History The name ''muscarine'' derives from that o ...

Mycotoxin
A mycotoxin (from the Greek μύκης , "fungus" and τοξίνη , "toxin") is a toxic secondary metabolite produced by organisms of kingdom Fungi and is capable of causing disease and death in both humans and other animals. The term 'mycotoxin' is usually reserved for the toxic chemical products produced by fungi that readily colonize crops. Examples of mycotoxins causing human and animal illness include aflatoxin, citrinin, fumonisins, ochratoxin A, patulin, trichothecenes, zearalenone, and ergot alkaloids such as ergotamine. One mold species may produce many different mycotoxins, and several species may produce the same mycotoxin. Production Most fungi are aerobic (use oxygen) and are found almost everywhere in extremely small quantities due to the diminute size of their spores. They consume organic matter wherever humidity and temperature are sufficient. Where conditions are right, fungi proliferate into colonies and mycotoxin levels become high. The reason for the product ...
