Lichenomphalia Chromacea
''Lichenomphalia chromacea'' is a species of basidiolichen in the family Hygrophoraceae. It is found in southern Australia. The yellow-orange fruiting bodies of the species are mushroom-like, with a cap width of typically less than . The thallus of the lichen is a greenish, granular layer of fungal hyphae and algae on the soil around the base of the stipe. Taxonomy The species was first scientifically described as a new species by John Burton Cleland, based on specimens collected from South Australia. In 1978, Scott Redhead and Thomas Kuyper transferred it to the genus ''Botrydina'', and a year later—following changes to the rules for botanical nomenclature—to ''Phytoconis''. Both of these genera have since been synonymized with ''Lichenomphalia''. Tom May and Alec Wood proposed it be classified in ''Omphalina'' in 1995. In 2002, the basidiolichen genus ''Lichenomphalia'' was circumscribed, and this species was one of several that were transferred to it. Descrip ...

John Burton Cleland
Sir John Burton Cleland CBE (22 June 1878 – 11 August 1971) was a renowned Australian naturalist, microbiologist, mycologist and ornithologist. He was Professor of Pathology at the University of Adelaide and was consulted on high-level police inquiries, such as the famous Taman Shud Case in 1948 and later. He also studied the transmission of dengue virus by the mosquito Stegomyia fasciata (Aedes aegypti). Early life and education John Burton Cleland was born in Norwood, South Australia a grandson of John Fullerton Cleland and son of Dr William Lennox Cleland (1847–1918) and Matilda Lauder Cleland née Burton (1848–1928) a daughter of John Hill Burton FRSE. He attended Prince Alfred College and the universities of Adelaide and Sydney, graduating in medicine in 1900. Marriage and family Cleland married Dora Isabel Paton (1880–1955) a daughter of Rev David Paton DD (1841–1907), minister of Chalmers Presbyterian Church, North Terrace, Adelaide, and Isabella Ann Mc ...

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...

Lichenomphalia Umbellifera
''Lichenomphalia umbellifera'', also known as the lichen agaric or the green-pea mushroom lichen, is a species of basidiolichen in the family Hygrophoraceae. ''L. umbellifera'' forms a symbiotic relationship with unicellular algae in the genus ''Coccomyxa.'' It is regarded as nonpoisonous. The mushroom is white to yellowish-tan and hygrophanous, and occurs throughout most of the year on damp soil and rotting wood. It can be found in the Northern Hemisphere, particularly in the region of the Arctic. In the Pacific Northwest, it is common and can be found northward from Santa Cruz. Its cap grows up to 3cm wide. Its stalk is 1–3cm tall and 1–3mm wide. The spores are white or yellowish. Taxonomy The species was first described by Carl Linnaeus in 1753 as ''Agaricus umbelliferus''. It was transferred to '' Lichenomphalia'' in 2002. ''L. umbellifera'' has a wide geographic range and displays a considerable amount of phenotypic plasticity, but phylogenetic research has co ...

Lichenomphalia Tasmanica
''Lichenomphalia tasmanica'' is a species of basidiolichen in the family Hygrophoraceae. It is found in Tasmania, Australia. It has a bright scaley thallus that grows like a green crust on rich soil between rocks. Occasionally. the lichen produces small, bright yellow-orange mushroom-like fruiting bodies. Taxonomy The lichen was formally described as a new species in 2012 by Gintaras Kantvilas. The type specimen was collected on the track to Nevada Peak at an altitude of , where it was found growing on the ground between boulders in heathland. The specific epithet refers to the type locality. The authors explained that they had seen the unidentifiable sterile crust form of the lichen for many years before observing its fruiting stage, noting "it was very exciting when the species was finally encountered fertile, producing not ascomata as expected but attractive, yellow-orange, mushroom-like basidiocarps". Description The lichen has a bright green squamulose thallus c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lichenomphalia
''Lichenomphalia'' is both a basidiolichen and an agaric genus. Most of the species have inconspicuous lichenized thalli that consist of scattered, small, loose, nearly microscopic green balls or foliose small flakes containing single-celled green algae in the genus '' Coccomyxa'', all interconnected by a loose network of hyphae. The agaric fruit bodies themselves are nonlichenized and resemble other types of omphalinoid mushrooms. These agarics lack clamp connections and do not form hymenial cystidia. The basidiospores are hyaline, smooth, thin-walled, and nonamyloid. Most of the species were originally classified in the genera ''Omphalina'' or '' Gerronema''. Historically the species were classified with those other genera in the family, the Tricholomataceae together with the nonlichenized species. ''Lichenomphalia'' species can be grouped into brightly colored taxa, with vivid yellow and orange colors, versus the grey brown group, depending upon the microscopic pigmentation ...

Woodland
A woodland () is, in the broad sense, land covered with trees, or in a narrow sense, synonymous with wood (or in the U.S., the ''plurale tantum'' woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American, and Australian English explained below). Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher-density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are often referred to as forests. Extensive efforts by conservationist groups have been made to preserve woodlands from urbanization and agriculture. For example, the woodlands of Northwest Indiana have been preserved as part of the Indiana Dunes. Definitions United Kingdom ''Woodland'' is used in British woodland management to mean tre ...

Heathland
A heath () is a shrubland habitat found mainly on free-draining infertile, acidic soils and characterised by open, low-growing woody vegetation. Moorland is generally related to high-ground heaths with—especially in Great Britain—a cooler and damper climate. Heaths are widespread worldwide but are fast disappearing and considered a rare habitat in Europe. They form extensive and highly diverse communities across Australia in humid and sub-humid areas where fire regimes with recurring burning are required for the maintenance of the heathlands.Specht, R.L. 'Heathlands' in 'Australian Vegetation' R.H. Groves ed. Cambridge University Press 1988 Even more diverse though less widespread heath communities occur in Southern Africa. Extensive heath communities can also be found in the Texas chaparral, New Caledonia, central Chile, and along the shores of the Mediterranean Sea. In addition to these extensive heath areas, the vegetation type is also found in scattered locations acro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Ellipsoid
An ellipsoid is a surface that may be obtained from a sphere by deforming it by means of directional scalings, or more generally, of an affine transformation. An ellipsoid is a quadric surface; that is, a surface that may be defined as the zero set of a polynomial of degree two in three variables. Among quadric surfaces, an ellipsoid is characterized by either of the two following properties. Every planar cross section is either an ellipse, or is empty, or is reduced to a single point (this explains the name, meaning "ellipse-like"). It is bounded, which means that it may be enclosed in a sufficiently large sphere. An ellipsoid has three pairwise perpendicular axes of symmetry which intersect at a center of symmetry, called the center of the ellipsoid. The line segments that are delimited on the axes of symmetry by the ellipsoid are called the ''principal axes'', or simply axes of the ellipsoid. If the three axes have different lengths, the figure is a triaxial ellipsoid (r ... [...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.
