Entoloma Rodwayi
''Entoloma rodwayi'', known as the green stem pinkgill, is a species of fungus in the Entolomataceae family of mushrooms. A yellowish green mushroom with pink gills and spores, it is found in wet forests of Tasmania. Taxonomy First named as ''Leptonia rodwayi'' by British mycologist George Edward Massee in 1898, it was transferred to the genus '' Entoloma'' in a 1980 publication by German mycologist Egon Horak. It was named after Tasmanian botanist Leonard Rodway. The genus ''Entoloma'' is well represented in Australia, particularly Tasmania, and ''E. rodwayi'' is one of many unusually coloured members, others being shades of blue and purple as well as green. Description The cap is up to 3 cm (1.2 in) in diameter, and is conical or convex, before flattening out as the mushroom ages. The centre is sometimes depressed. When dried, the mushroom transforms from yellow-green to a vivid blue-green. It can be confused with some other green mushrooms such as the larger and m ...

George Edward Massee
George Edward Massee (20 December 1845 – 16 February 1917) was an English mycologist, plant pathologist, and botanist. Background and education George Massee was born in Scampston, East Riding of Yorkshire, the son of a farmer. He was educated at York School of Art and claimed to have attended Downing College, Cambridge, though no record exists of him in the University or College Records. South America and the Foreign Legion Massee had an early interest in natural history, publishing an article on British woodpeckers at the age of 16 and compiling a portfolio of botanical paintings. Through the influence of Richard Spruce, a family relative, he was able to travel on a botanical expedition to Panama and Ecuador, where, despite considerable hardships, he collected orchids and other plants. On his return, Massee joined the French Foreign Legion, hoping to see combat in the Franco-Prussian War, but, the war being almost over, he was prevailed upon to return home to the farm. H ...

Fungus
A fungus (plural, : fungi or funguses) is any member of the group of Eukaryote, eukaryotic organisms that includes microorganisms such as yeasts and Mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as a Kingdom (biology), kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entolomataceae
The Entolomataceae, also known as Rhodophyllaceae, are a large family of pink-spored terrestrial gilled mushrooms which includes the genera ''Entoloma'', '' Rhodocybe'', and ''Clitopilus''. The family collectively contains over 1500 species, the large majority of which are in ''Entoloma''. Genera formerly known as ''Leptonia'' and ''Nolanea'', amongst others, have been subsumed into ''Entoloma''. Mushrooms in the Entolomataceae typically grow in woodlands or grassy areas and have attached gills, differentiating them from the Pluteaceae, which have free gills. Description The very large family Entolomataceae has a cosmopolitan distribution, and species are common in both temperate and tropical climates. Although the shape of the fruiting body and many microscopic characteristics are very diverse, it forms a well-defined group due to the distinctive spores: the spore print is pink (or brownish or greyish pink) and the spores are ornamented with bumps or ridges, or have a shar ...

Mushroom
A mushroom or toadstool is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground, on soil, or on its food source. ''Toadstool'' generally denotes one poisonous to humans. The standard for the name "mushroom" is the cultivated white button mushroom, '' Agaricus bisporus''; hence the word "mushroom" is most often applied to those fungi ( Basidiomycota, Agaricomycetes) that have a stem ( stipe), a cap ( pileus), and gills (lamellae, sing. lamella) on the underside of the cap. "Mushroom" also describes a variety of other gilled fungi, with or without stems, therefore the term is used to describe the fleshy fruiting bodies of some Ascomycota. These gills produce microscopic spores that help the fungus spread across the ground or its occupant surface. Forms deviating from the standard morphology usually have more specific names, such as " bolete", " puffball", " stinkhorn", and "morel", and gilled mushrooms themselves are often called " agarics" in ...

Entoloma
''Entoloma'' is a large genus of terrestrial pink-gilled mushrooms, with about 1,000 species. Most have a drab appearance, pink gills which are attached to the stem, a smooth thick cap, and angular spores. Many entolomas are saprobic but some are mycorrhizal. The best-known member of the genus is the livid agaric ('' Entoloma sinuatum''), responsible for a number of poisonings over the years in Europe and North America, and ''Entoloma rhodopolium'' in Japan. Some southern hemisphere species such as '' Entoloma rodwayi'' and ''Entoloma viridomarginatum'' from Australia, and ''Entoloma hochstetteri'' from New Zealand, are very colourful, with caps of unusual shades of green and blue-green. Most entolomas are dull shades of olive, brown, or grey. Etymology The part '' ἐντός'' means "within, inside". The part "loma" is a noun-forming element derived from Greek '' λῶμ(α)'', "fringe, hem" and used in the botanical taxonomy for naming plants distinguished by having a ...

Leonard Rodway
Leonard Rodway (5 October 1853 – 9 March 1936) was an English-born Australian dentist and botanist. Early life Rodway was born in Torquay Devon, England, the thirteenth child of Henry Barron Rodway, a dentist and inventor of the Rodway life buoy, and his wife Elizabeth, ''née'' Allin. Leonard Rodway was educated in Birmingham and aboard the Thames Nautical Training College ship, ''Worcester'', obtaining double first-class certificates. He served for three years as a midshipman in the merchant service, but decided to follow his father into dentistry. He obtained the licentiateship of the Royal College of Surgeons, London in 1878.Elias, A. (1988). Rodway, Leonard (1853–1936). ''Australian Dictionary of Biography'', Vol. 11 MUP, p 436-437, 1988. Career Rodway emigrated to Australia and settled in Hobart, Tasmania. Rodway was registered under the first Tasmanian Dental Act 1884, but is mainly remembered for his interest in botany. In 1896 he was appointed honorary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pileus (mycology)
The pileus is the technical name for the cap, or cap-like part, of a basidiocarp or ascocarp ( fungal fruiting body) that supports a spore-bearing surface, the hymenium.Moore-Landecker, E: "Fundamentals of the Fungi", page 560. Prentice Hall, 1972. The hymenium ( hymenophore) may consist of lamellae, tubes, or teeth, on the underside of the pileus. A pileus is characteristic of agarics, boletes, some polypores, tooth fungi, and some ascomycetes. Classification Pilei can be formed in various shapes, and the shapes can change over the course of the developmental cycle of a fungus. The most familiar pileus shape is hemispherical or ''convex.'' Convex pilei often continue to expand as they mature until they become flat. Many well-known species have a convex pileus, including the button mushroom, various '' Amanita'' species and boletes. Some, such as the parasol mushroom, have distinct bosses or umbos and are described as '' umbonate''. An umbo is a knobby protrusion at th ...

Cortinarius Austrovenetus
''Cortinarius austrovenetus'', alternately known as ''Dermocybe austroveneta'' and commonly known as the green skin-head but also known as green dermocybe is an inedible brightly coloured green gilled fungus that naturally occurs in south eastern Australia. Taxonomy Initially described as ''Cortinarius austrovenetus'' by Australian naturalist John Burton Cleland in 1928, this mushroom along with many other members of the group was separated from the huge genus ''Cortinarius'', and placed in the newer genus '' Dermocybe'', commonly called skin-heads, derived from the meaning of their scientific names. However, this genus is often treated as a subgenus of ''Cortinarius'' only. In 2007, Bruno Gasparini suggested that ''C. austrovenetus'' is the same species as another ''Cortinarius'' in subgenus ''Dermocybe'', '' C. walkerae''. If this is true, ''C. austrovenetus'' is a later synonym and the name C. walkerae would take precedence. Description The fruit bodie ...

Hygrocybe
''Hygrocybe'' is a genus of agarics (gilled fungi) in the family Hygrophoraceae. Called waxcaps in English (sometimes waxy caps in North America), basidiocarps (fruit bodies) are often brightly coloured and have dry to waxy caps, white spores, and smooth, ringless stems. In Europe they are characteristic of old, unimproved grasslands (termed waxcap grasslands) which are a declining habitat, making many ''Hygrocybe'' species of conservation concern. Four of these waxcap-grassland species, '' Hygrocybe citrinovirens'', '' H. punicea'', '' H. spadicea'', and '' H. splendidissima'', are assessed as globally "vulnerable" on the IUCN Red List of Threatened Species. Elsewhere waxcaps are more typically found in woodlands. Most are ground-dwelling and all are believed to be biotrophs. Around 150 species are recognized worldwide. Fruit bodies of several ''Hygrocybe'' species are considered edible and are sometimes offered for sale in local markets. Taxonomy History ''Hygrocybe'' was f ...

It is an important diagnostic character in most handbooks for identifying mushrooms. It shows the colour of the mushroom spores if viewed en masse. Method A spore print is made by placing the spore-producing surface flat on a sheet of dark and white paper or on a sheet of clear, stiff plastic, which facilitates moving the spore print to a darker or lighter surface for improved contrast; for example, i ...

Basidiospore
A basidiospore is a reproductive spore produced by Basidiomycete fungi, a grouping that includes mushrooms, shelf fungi, rusts, and smuts. Basidiospores typically each contain one haploid nucleus that is the product of meiosis, and they are produced by specialized fungal cells called basidia. Typically, four basidiospores develop on appendages from each basidium, of which two are of one strain and the other two of its opposite strain. In gills under a cap of one common species, there exist millions of basidia. Some gilled mushrooms in the order Agaricales have the ability to release billions of spores. The puffball fungus '' Calvatia gigantea'' has been calculated to produce about five trillion basidiospores. Most basidiospores are forcibly discharged, and are thus considered ballistospores. These spores serve as the main air dispersal units for the fungi. The spores are released during periods of high humidity and generally have a night-time or pre-dawn peak concentration ...

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] |
