Squamanitaceae
The Squamanitaceae are a family of fungi in the order Agaricales. All species in the family are agarics (gilled mushrooms). Species in two genera, '' Dissoderma'' and '' Squamanita'', are parasitic on other agarics. Members of the ''Squamanitaceae'' are found worldwide. Taxonomy The family was first proposed in 1981 by Dutch mycologist Walter Jülich. Its current circumscription is the result of molecular research, based on cladistic analysis of DNA sequences.

Phaeolepiota Aurea
''Phaeolepiota'' is a genus of fungi in the family Squamanitaceae. The genus is monotypic, containing the single species ''Phaeolepiota aurea''. Commonly known as golden bootleg or golden cap, ''P. aurea'' is an agaric (gilled mushroom) found throughout North America and Eurasia – often in groups and next to nettles. Molecular research, based on cladistic analysis of DNA sequences, shows that ''Phaeolepiota'' is close to and may be congeneric with ''Cystoderma''. Description The mushroom is large and golden, and its stem has a skirt-like ring. The spores are brown. Economic Usage Fruit bodies of ''Phaeolepiota aurea'' have been considered edible and are collected for food in Russia and China. It is not, however, recommended for consumption since it can cause gastrointestinal upset. Studies have shown that fruit bodies contain unacceptable amounts of both cadmium and cyanide Cyanide is a naturally occurring, rapidly acting, toxic chemical that can exist in many ...

Squamanita Umbonata
''Squamanita'' is a genus of parasitic fungi in the family Squamanitaceae. Basidiocarps (fruit bodies) superficially resemble normal agarics (gilled mushrooms) but emerge from parasitized fruit bodies of deformed host agarics. Taxonomy The genus was created in 1946 by Swiss mycologist Emil Imbach to accommodate an unusual agaric species, ''Squamanita schreieri'', which L. Schreier had earlier described and illustrated as "''Tricholoma'' X". In 1965 Dutch mycologist Cornelis Bas expanded the genus to five species, all of which were characterized by arising from "sclerotial bodies". The possibility that ''Squamanita'' might be parasitic on other agarics (the remains of which formed the "sclerotial bodies") was noted by British mycologist Derek Reid in 1983. The discovery of a host fruit body that formed its own pileus together with three ''Squamanita'' pilei confirmed the parasitic nature of the genus, a discovery subsequently featured in ''Nature'' under the title 'Mycological m ...

Dissoderma
''Dissoderma'' is a genus of parasitic fungi in the family Squamanitaceae. Basidiocarps (fruit bodies) superficially resemble normal agarics (gilled mushrooms) but emerge from parasitized fruit bodies of deformed host agarics. Taxonomy ''Dissoderma'' was created in 1948 as a subgenus of ''Cystoderma'' and raised to generic rank in 1973. Though French mycologist Marcel Bon recognized and expanded the genus in 1999, most other mycologists considered ''Dissoderma'' synonymous with '' Squamanita''. Molecular research, based on cladistic analysis of DNA sequences, has however confirmed ''Dissoderma'' as a genus distinct from ''Squamanita''. A number of species previously referred to ''Squamanita'' have accordingly been transferred to ''Dissoderma''. Description ''Dissoderma'' species can be distinguished from ''Squamanita'' species by their violet-grey pilei (caps) and upper stipes (stems). The lower parts of the stipes are host tissue and as such are often distinct and different ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Floccularia
''Floccularia'' is a genus of fungi in the order Agaricales. There are four recognized species in the genus, which have a widespread distribution, especially in northern temperate regions. Two former species are now classified as a '' Cercopemyces'' and an ''Amanita'' (or more specifically an ''Aspidella'', Amanitaceae). ''Floccularia'' was circumscribed by Czech mycologist Zdeněk Pouzar in 1957. ''Floccularia albolanaripes'' and ''F. luteovirens'' are known to be edible.

Mycologist
Mycology is the branch of biology concerned with the study of fungi, including their genetic and biochemical properties, their taxonomy and their use to humans, including as a source for tinder, traditional medicine, food, and entheogens, as well as their dangers, such as toxicity or infection. A biologist specializing in mycology is called a mycologist. Mycology branches into the field of phytopathology, the study of plant diseases, and the two disciplines remain closely related because the vast majority of plant pathogens are fungi. Overview Historically, mycology was a branch of botany because, although fungi are evolutionarily more closely related to animals than to plants, this was not recognized until a few decades ago. Pioneer mycologists included Elias Magnus Fries, Christian Hendrik Persoon, Anton de Bary, Elizabeth Eaton Morse, and Lewis David von Schweinitz. Beatrix Potter, author of ''The Tale of Peter Rabbit'', also made significant contributions to the field. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Floccularia Albolanaripes
''Floccularia albolanaripes'' is a species of fungus in the family Agaricaceae. Mushrooms are characterized by their yellow caps with a brownish center and scales over the margin, and the conspicuous remains of a partial veil that is left on the stipe. The species grows in the Pacific Northwest and the Rocky Mountains of North America, and in India. Taxonomy The species was first described as ''Armillaria albolanaripes'' by American mycologist George F. Atkinson in 1908. The type specimens were collected from Corvallis, Oregon on November 6, 1906. It was known as an ''Armillaria'' for several decades until members of that genus with amyloid spores and lacking black rhizomorphs were transferred to ''Floccularia'' in 1987. Description The cap is convex to flattened (sometimes with a shallow umbo), measuring in diameter. Its color is bright-yellow to orange-yellow and then later brownish, and it has flattened brownish scales over the center. The whitish cap margin is rolled in ...

Leucopholiota Decorosa
''Leucopholiota decorosa'' is a species of fungus in the mushroom family Tricholomataceae. Commonly known as the decorated pholiota, it is distinguished by its fruit body which is covered with pointed brown, curved scales on the cap and stem, and by its white gills. Found in the eastern United States, France, and Pakistan, it is saprobic, growing on the decaying wood of hardwood trees. ''L. decorosa'' was first described by American mycologist Charles Horton Peck as ''Agaricus decorosus'' in 1873, and the species has been transferred to several genera in its history, including '' Tricholoma'', ''Tricholomopsis'', '' Armillaria'', and ''Floccularia''. Three American mycologists considered the species unique enough to warrant its own genus, and transferred it into the new genus '' Leucopholiota'' in a 1996 publication. Lookalike species with similar colors and scaly fruit bodies include ''Pholiota squarrosoides'', '' Phaeomarasmius erinaceellus'', and '' Leucopholiota li ...

Cystoderma Carcharias
''Cystoderma carcharias'', is a species of agaric in the fungal family Agaricaceae. It has a widespread distribution, and has been collected in coniferous forests and grasslands in Asia, Europe, North America, and the subantarctic islands. In the field, fruit bodies are characterized by a pink cap up to broad, a well-developed ring on the stem, and an unpleasant odour. Taxonomy The species was first described scientifically by Christian Hendrik Persoon, who named it ''Agaricus carcharias'' in 1794. Swiss mycologist Victor Fayod assigned it its current name in 1889. The specific epithet ''carcharias'' is probably derived from the Greek καρχαρός (''karcharos'') which means sharp, pointed or jagged. καρχαρίας (''karcharias'') is translated as shark. Description The fruiting body of ''Cystoderma carcharias'' is a relatively small agaric. The fruiting body is characterised by an off-white and pale pink-tinged cap with a distinct darker central spot, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DNA Sequences
A nucleic acid sequence is a succession of bases signified by a series of a set of five different letters that indicate the order of nucleotides forming alleles within a DNA (using GACT) or RNA (GACU) molecule. By convention, sequences are usually presented from the 5' end to the 3' end. For DNA, the sense strand is used. Because nucleic acids are normally linear (unbranched) polymers, specifying the sequence is equivalent to defining the covalent structure of the entire molecule. For this reason, the nucleic acid sequence is also termed the primary structure. The sequence has capacity to represent information. Biological deoxyribonucleic acid represents the information which directs the functions of an organism. Nucleic acids also have a secondary structure and tertiary structure. Primary structure is sometimes mistakenly referred to as ''primary sequence''. Conversely, there is no parallel concept of secondary or tertiary sequence. Nucleotides Nucleic acids cons ...
