Leucocoprinus Straminellus
''Leucocoprinus straminellus'' is a species of mushroom producing fungus in the family Agaricaceae. Like other ''Leucocoprinus'' species it may have originated in a tropical climate but now finds a home in plant pots, greenhouses and compost piles in many countries. ''Leucocoprinus straminellus'' is described as being similar to the more commonly known ''Leucocoprinus birnbaumii'' but it is smaller and a lighter shade of yellow with smaller spores that lack a germ pore. It is also described as being superficially similar to '' Leucocoprinus fragilissimus'' but slightly more robust with flesh that is less translucent. Taxonomy It was first described in 1865 by the Italian botanist Francesco Baglietto who classified it as ''Agaricus straminellus''. In 1887 the Italian mycologist Pier Andrea Saccardo classified it as ''Lepiota straminella.'' It was reclassified as ''Leucocoprinus straminellus'' by the Italian mycologists Roberto Narducci and Vincenzo Caroti in 1995. However ...

Francesco Baglietto
Francesco Baglietto (2 September 1826 – 24 February 1916) was an Italian physician and botanist, known for his studies on cryptogams, particularly on lichens. Biography Francesco Baglietto was born in Voltri, Italy, on 2 September 1816. A pupil of Giuseppe De Notaris, Baglietto specialized in the study of lichens, a subject on which he left numerous publications. Together with de Notaris and Vincenzo de Cesati, they founded the (Italian Cryptogamic Society), which published the scientific journal, journal ''Commentario della Società crittogamologica italiana'' ("Commentary of the Italian Cryptogamic Society"). The society had the aim of creating and publishing the Italian cryptogamic herbarium, intended to be an all-encompassing collection of all types of cryptogams, including mosses, lichens, ferns, and mushrooms. Together with V. de Cesati and G. de Notaris, Baglietto published two series of the exsiccata work ''Erbario crittogamico Italiano'' with altogether 3000 numbered ...

Agaricaceae
The Agaricaceae are a family of basidiomycete fungi and include the genus ''Agaricus'', as well as basidiomycetes previously classified in the families Tulostomataceae, Lepiotaceae, and Lycoperdaceae. Taxonomy The family Agaricaceae was published by French botanist François Fulgis Chevallier in 1826. It is named after the type genus ''Agaricus'', originally circumscribed by Carl Linnaeus in his 1753 work ''Species Plantarum''. In his authoritative 1986 classification of the Agaricales, Rolf Singer divided the Agaricaceae into four tribes distinguished largely by spore color: ''Leucocoprineae'', ''Agariceae'', ''Lepioteae'', and ''Cystodermateae''. Genera once classified in the families Tulostomataceae, Battarreaceae, Lycoperdaceae, and Mycenastraceae have since been moved to the Agaricaceae based on molecular phylogenetics studies. According to a standard reference text, the Agaricaceae contains 85 genera and 1340 species. Description Agaricaceae species use a wide variety o ...

Leucocoprinus Flavescens
''Leucocoprinus flavescens'' is a species of mushroom-producing fungus in the family Agaricaceae. Taxonomy It was first described in 1907 by the American mycologist Andrew Price Morgan who classified it as ''Lepiota flavescens'' and reclassified as ''Leucocoprinus flavescens'' by the American botanist and mycologist Helen Vandervort Smith in 1981. Description ''Leucocoprinus flavescens'' is a small mushroom with very thin white to pale yellow flesh. Cap: 1–2.5cm or up to 4cm at the extreme. Ovoid to campanulate (bell shaped) with an umbo before flattening or becoming convex with age. The surface is pale greenish-yellow and is covered in fine powdery scales with smooth striations whilst the central disk is brownish but smooth. Stem: 2–6 cm and 1–2 mm in thickness with a slightly swollen base of 3–5 mm thick where white mycelium may be present. The stem surface is pale sulphur-yellow and is likewise covered with fine powdery scales like the cap though these may disap ...

Melzer's Reagent
Melzer's reagent (also known as Melzer's iodine reagent, Melzer's solution or informally as Melzer's) is a chemical reagent used by mycologists to assist with the identification of fungi, and by phytopathologists for fungi that are plant pathogens. Composition Melzer's reagent is an aqueous solution of chloral hydrate, potassium iodide, and iodine. Depending on the formulation, it consists of approximately 2.50-3.75% potassium iodide and 0.75–1.25% iodine, with the remainder of the solution being 50% water and 50% chloral hydrate. Melzer's is toxic to humans if ingested due to the presence of iodine and chloral hydrate. Due to the legal status of chloral hydrate, Melzer's reagent is difficult to obtain in the United States. In response to difficulties obtaining chloral hydrate, scientists at Rutgers formulated Visikol (compatible with Lugol's iodine) as a replacement. In 2019, research showed that Visikol behaves differently to Melzer’s reagent in several key situations, notin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germ Pore
A germ pore is a small pore in the outer wall of a fungal spore through which the germ tube exits upon germination. It can be apical or eccentric in its location, and, on light microscopy, may be visualized as a lighter coloured area on the cell wall. Apical germ pore is mushroom spore which has a pore at one end. Some spores have a hole in the cell wall where the first strand of germinating mycelium emerges. If the cell wall is divided from one end to the other, this is called a germ slit. Commonly the germ pore is at one end of the mushroom spore and is called an apical pore. Mushroom genera with apical germ pores include ''Agrocybe'', ''Panaeolus'', ''Psilocybe'', and ''Pholiota''. See also *mycelium *spore In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, f ... External linksIMA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leucocoprinus Fragilissimus
''Leucocoprinus fragilissimus'', commonly known as the fragile dapperling, is a species of gilled mushroom in the family Agaricaceae. Taxonomy As with many of the most well known ''Leucocoprinus'' species the taxonomic history of this species is complex with numerous early mycologists classifying it independently before the species were later merged. As a result the authorities recognised today aren't necessarily the first to document this species but rather the first to document the basionym which ultimately ended up classified as ''Leucocoprinus fragilissimus.'' The first description of this species was made in 1805 by Johannes Baptista von Albertini and Lewis David de Schweinitz who classified it as ''Agaricus flammula.'' This basionym was reclassified as ''Lepiota flammula'' in 1874 by the French botanist Claude Casimir Gillet and then ''Pholiota flammula'' in 1912 by the Italian mycologist Vincenzo Migliozzi. In 1853 ''Hiatula fragilissima'' was described by the British b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leucocoprinus Birnbaumii
''Leucocoprinus birnbaumii'' is a species of gilled mushroom in the family Agaricaceae. It is common in the tropics and subtropics. However, in temperate regions, it frequently occurs in greenhouses and flowerpots, hence its common names of flowerpot parasol and plantpot dapperling. It is considered to be toxic if consumed. Taxonomy The species was first described as ''Agaricus luteus'' in 1788 by the English mycologist James Bolton who described an observation from a hothouse near Halifax, three years earlier in 1785. Bolton also provided an illustration of the mushrooms. At the time gilled species were classified as ''Agaricus'' and ''luteus'' comes from the Latin for yellow or yellow-orange. Bolton suggested the common name of 'Yellow Cottony Agaric' in reference to the soft, scaly texture of the mushroom. However the name ''A. luteus'' had already been used to describe an unrelated ''Russula'' species and was published in 1778 by William Hudson so Bolton's ''A. ...
