Phallus Hadriani
''Phallus hadriani'', commonly known as the dune stinkhorn or the sand stinkhorn, is a species of fungus in the Phallaceae (stinkhorn) family. It is a widely distributed species, and is native to Asia, Europe, and North America. In Australia, it is probably an introduced species. The stalk of the fruit body reaches up to tall by thick, and is spongy, fragile, and hollow. At the top of the stem is a ridged and pitted, thimble-like cap over which is spread olive-colored spore slime (gleba). Shortly after emerging, the gleba liquefies and releases a fetid odor that attracts insects, which help disperse the spores. Said to be edible in its immature egg-like stage, it typically grows in public lawns, yards and gardens, usually in sandy soils. ''Phallus hadriani'' may be distinguished from the similar '' P. impudicus'' (the common stinkhorn) by the presence of a pink or violet-colored volva at the base of the stem, and by differences in odor. Taxonomy The species was first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Étienne Pierre Ventenat
Étienne Pierre Ventenat (1 March 1757 – 13 August 1808) was a French botanist born in Limoges. He was the brother of naturalist Louis Ventenat (1765–1794). While employed as director of the ecclesiastic library Sainte-Geneviève in Paris, Ventenat took a trip to England. Here he investigated the country's botanical gardens, inspiring him to pursue a vocation in sciences. Following his time at library he became an active botanist, studying under and collaborating with botanist Charles Louis L'Héritier de Brutelle (1746–1800). In 1795 he was elected a member of the ''Institut national des sciences et des arts'', later known as the ''Académie des sciences''. In 1794 he wrote a treatise on the principles of botany titled ''Principes de botanique, expliqués au Lycée républicain par Ventenat''. After publication he became so disappointed with its mediocrity that he reportedly made efforts to procure all copies of the book and have them destroyed. In 1798 he published a Fren ...

Christiaan Hendrik Persoon
Christiaan Hendrik Persoon (1 February 1761 Р16 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 G̦ttingen. 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 dona ...

Basidia
A basidium () is a microscopic sporangium (a spore-producing structure) found on the hymenophore of fruiting bodies of basidiomycete fungi which are also called tertiary mycelium, developed from secondary mycelium. Tertiary mycelium is highly-coiled secondary myceliuma dikaryon. The presence of basidia is one of the main characteristic features of the Basidiomycota. A basidium usually bears four sexual spores called basidiospores; occasionally the number may be two or even eight. In a typical basidium, each basidiospore is borne at the tip of a narrow prong or horn called a sterigma (), and is forcibly discharged upon maturity. The word ''basidium'' literally means "little pedestal", from the way in which the basidium supports the spores. However, some biologists suggest that the structure more closely resembles a club. An immature basidium is known as a basidiole. Structure Most basidiomycota have single celled basidia (holobasidia), but in some groups basidia can be multice ...

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] |
Hyaline
A hyaline substance is one with a glassy appearance. The word is derived from el, ὑάλινος, translit=hyálinos, lit=transparent, and el, ὕαλος, translit=hýalos, lit=crystal, glass, label=none. Histopathology Hyaline cartilage is named after its glassy appearance on fresh gross pathology. On light microscopy of H&E stained slides, the extracellular matrix of hyaline cartilage looks homogeneously pink, and the term "hyaline" is used to describe similarly homogeneously pink material besides the cartilage. Hyaline material is usually acellular and proteinaceous. For example, arterial hyaline is seen in aging, high blood pressure, diabetes mellitus and in association with some drugs (e.g. calcineurin inhibitors). It is bright pink with PAS staining. Ichthyology and entomology In ichthyology and entomology, ''hyaline'' denotes a colorless, transparent substance, such as unpigmented fins of fishes or clear insect wings. Resh, Vincent H. and R. T.

Mycelium
Mycelium (plural mycelia) is a root-like structure of a fungus consisting of a mass of branching, thread-like hyphae. Fungal colonies composed of mycelium are found in and on soil and many other substrate (biology), substrates. A typical single spore germinates into a Monokaryon, monokaryotic mycelium, which cannot reproduce sexually; when two compatible monokaryotic mycelia join and form a dikaryotic mycelium, that mycelium may form sporocarp (fungi), fruiting bodies such as mushrooms. A mycelium may be minute, forming a colony that is too small to see, or may grow to span thousands of acres as in ''Armillaria''. Through the mycelium, a fungus absorbs nutrients from its environment. It does this in a two-stage process. First, the hyphae secrete enzymes onto or into the food source, which break down biopolymers, biological polymers into smaller units such as monomers. These monomers are then absorbed into the mycelium by facilitated diffusion and active transport. Mycelia are v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhizomorphs
Mycelial cords are linear aggregations of parallel-oriented hyphae. The mature cords are composed of wide, empty vessel hyphae surrounded by narrower sheathing hyphae. Cords may look similar to plant roots, and also frequently have similar functions; hence they are also called rhizomorphs (literally, "root-forms"). As well as growing underground or on the surface of trees and other plants, some fungi make mycelial cords which hang in the air from vegetation. Mycelial cords are capable of conducting nutrients over long distances. For instance, they can transfer nutrients to a developing fruiting body, or enable wood-rotting fungi to grow through soil from an established food base in search of new food sources. For parasitic fungi, they can help spread infection by growing from established clusters to uninfected parts. The cords of some wood-rotting fungi (like ''Serpula lacrymans'') may be capable of penetrating masonry. The mechanism of the cord formation is not yet precisely unde ...

Hadrianus Junius
Hadrianus Junius (1511–1575), also known as Adriaen de Jonghe, was a Dutch physician, classical scholar, translator, lexicographer, antiquarian, historiographer, emblematist, school rector, and Latin poet. He is not to be confused with several namesakes (including a seventeenth-century Amsterdam school rector). He was not related to Franciscus Junius. Biography Life Youth and education Adriaen de Jonge or Hadrianus Junius, was born in the West Frisian town of Hoorn on 1 July 1511, from a family of local regents. He attended the Latin School in Haarlem. At the relatively advanced age of 23, he went to study in Louvain, where he spent a couple of years. He then embarked on his peregrinatio academica, which led him through Siena, Bologna, Venice and Rome. In his letters, he reports on his visits to the famous legal humanist Andrea Alciato, his attendance at an interrupted Greek-orthodox liturgical service in Venice, and on an experiment with glow-worms in the Bolognese coun ...
