Pseudocolus Fusiformis
''Pseudocolus fusiformis'' is a stinkhorn mushroom in the Phallaceae, a family well known for a remarkable range of fruit body types. It is the most widely distributed member of the genus ''Pseudocolus'' and has been found in the United States, Australia, Japan, Java, and the Philippines. It is common name, commonly known as the stinky squid, because of its fetid odor, and its three or four upright "arms" which are connected at the top. The malodorous smell comes from the dark greenish slimy gleba covering the inside faces of the arms, and attracts insects that help to disperse the spores. Taxonomy The first appearance of this species in the literature was in 1890, under the name ''Colus fusiformis'', when Eduard Fischer (mycologist), Eduard Fischer wrote a description based on a painting he found in the Paris Museum of Natural History. In his 1944 monograph on the Gasteromycetes of Australia and New Zealand, Gordon Herriot Cunningham considered this naming to be a ''nomen nud ...

Curtis Gates Lloyd
Curtis Gates Lloyd (July 17, 1859 – November 11, 1926) was an American mycologist known for both his research on the gasteroid and polypore fungi, as well as his controversial views on naming conventions in taxonomy. He had a herbarium with about 60,000 fungal specimens, and described over a thousand new species of fungi. Along with his two brothers John Uri Lloyd and Nelson Ashley Lloyd, he founded the Lloyd Library and Museum in Cincinnati. Early life Born on July 17, 1859 in Florence, Kentucky, Curtis Gates Lloyd was the third son of Nelson Marvin and Sophia Webster Lloyd. He and his family moved to Crittenden, Kentucky, in 1867, where Lloyd lived until he was 18. He moved to Cincinnati and was employed as an apprentice in Johnson's pharmacy. This was where he met Dr. John King, physician and editor of the ''American Dispensatory''; the close friendship they formed helped to fuel Lloyd's interest in botany. Lloyd earned his pharmacy certificate while working at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binomial Name
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 multic ...

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 � ... [...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 Diabetes, also known as diabetes mellitus, is a group of metabolic disorders characterized by a high blood sugar level (hyperglycemia) over a prolonged period of time. Symptoms often include frequent urination, increased thirst and increased ... and in association with some drugs (e.g. calcineurin inhibitors) ...

Ovoid
An oval () is a closed curve in a plane which resembles the outline of an egg. The term is not very specific, but in some areas (projective geometry, technical drawing, etc.) it is given a more precise definition, which may include either one or two axes of symmetry of an ellipse. In common English, the term is used in a broader sense: any shape which reminds one of an egg. The three-dimensional version of an oval is called an ovoid. Oval in geometry The term oval when used to describe curves in geometry is not well-defined, except in the context of projective geometry. Many distinct curves are commonly called ovals or are said to have an "oval shape". Generally, to be called an oval, a plane curve should ''resemble'' the outline of an egg or an ellipse. In particular, these are common traits of ovals: * they are differentiable (smooth-looking), simple (not self-intersecting), convex, closed, plane curves; * their shape does not depart much from that of an ellipse, an ...

Lanceolate
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lance
A lance is a spear designed to be used by a mounted warrior or cavalry soldier ( lancer). In ancient and medieval warfare, it evolved into the leading weapon in cavalry charges, and was unsuited for throwing or for repeated thrusting, unlike similar weapons of the javelin and pike family typically used by infantry. Lances were often equipped with a vamplate, a small circular plate to prevent the hand sliding up the shaft upon impact, and beginning in the late 14th century were used in conjunction with a lance rest attached to the breastplate. Though best known as a military and sporting weapon carried by European knights and men-at-arms, the use of lances was widespread throughout Asia, the Middle East, and North Africa wherever suitable mounts were available. Lancers of the medieval period also carried secondary weapons such as swords, battle axes, war hammers, maces and daggers for use in hand-to-hand combat, since the lance was often a one-use-per-engagement wea ...

Stipe (mycology)
In mycology, a stipe () is the stem or stalk-like feature supporting the cap of a mushroom. Like all tissues of the mushroom other than the hymenium, the stipe is composed of sterile hyphal tissue. In many instances, however, the fertile hymenium extends down the stipe some distance. Fungi that have stipes are said to be stipitate. The evolutionary benefit of a stipe is generally considered to be in mediating spore dispersal. An elevated mushroom will more easily release its spores into wind currents or onto passing animals. Nevertheless, many mushrooms do not have stipes, including cup fungi, puffballs, earthstars, some polypores, jelly fungi, ergots, and smuts. It is often the case that features of the stipe are required to make a positive identification of a mushroom. Such distinguishing characters include: # the texture of the stipe (fibrous, brittle, chalky, leathery, firm, etc.) # whether it has remains of a partial veil (such as an annulus or cortina) or unive ...

Pseudocolus Fusiformis 423862
''Pseudocolus'' is a genus of fungi in the stinkhorn family. The fruit bodies have three or four simple arms that are initially joined at the tip, but often break apart. The tips of the arms are covered with a slimy, foul-smelling gleba, which attracts insects that help disperse the spores. The genus contains three species: the type ''Pseudocolus fusiformis'', '' P. garciae'', similar in appearance to the type but with a pinkish to red, rather than orange color, and '' P. grandis'', found in India. Taxonomy The first appearance of the type species, ''Pseudocolus fusiformis'', in the literature was in 1890, under the name ''Colus fusiformis'', when Eduard Fischer wrote a description based on a painting he found in the Paris Museum of Natural History. In his 1944 monograph on the Gasteromycetes of Australia and New Zealand, Gordon Herriot Cunningham considered this naming to be a ''nomen nudum''—not published with an adequate description. However, it was valid under the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volva (mycology)
In mycology, a volva is a cup-like structure at the base of a mushroom that is a remnant of the universal veil, or the remains of the peridium that encloses the immature fruit bodies of gasteroid fungi. This macrofeature is important in wild mushroom identification because it is an easily observed, taxonomically significant feature that frequently signifies a member of Amanitaceae. This has particular importance due to the disproportionately high number of deadly poisonous species contained within that family. A mushroom's volva is often partially or completely buried in the ground, and therefore care must be taken to check for its presence when identifying mushrooms. Cutting or pulling mushrooms and attempting to identify them later without having noted this feature could be a fatal error.

Areolate
Lichens are composite organisms made up of multiple species: a fungal partner, one or more photosynthetic partners, and sometimes a basidiomycete yeast. They are regularly grouped by their external appearance – a characteristic known as their growth form. Lichenologists have described a dozen of these forms: areolate, byssoid, calicioid, cladoniform, crustose, filamentous, foliose, fruticose, gelatinous, leprose, placoidioid and squamulose. Of these, crustose, foliose and fruticose are the most commonly encountered. With the exception of calicioid lichens, growth forms are based on the appearance of the thallus, which is the vegetative (non-reproductive) part of the lichen. In most species, this form is determined by the lichen's fungal partner, though in a small number, it is instead the photobiont that determines the lichen's morphology. In some growth forms, the outermost layer of the thallus consists of tightly woven fungal . This layer, known as the cortex, may be foun ...
