Mycetinis Querceus
''Mycetinis querceus'' ( syn. ''Marasmius querceus'') is one of the garlic-scented mushrooms formerly in the genus ''Marasmius''. It has a reddish brown stipe, and usually grows on fallen oak leaves. Description The species can be described as follows: *The cap is reddish brown to pale brown, and is hygrophanous, drying to a paler colour. It measures around 1-2.5 cm in diameter. *The gills are white to cream and crowded. The spore powder is white. *The brownish stem can grow to 10 cm tall and up to 4 mm in diameter. It is powdery ("pruinose") or covered in minute hairs ("pubescent"), a feature which distinguishes it from ''M. scorodonius''. *The smell is strongly of garlic. *The spores are roughly ellipsoid and measure 7-10 µm x 4-5 µm. *There are no cheilocystidia (on the gill edge) or pleurocystidia (on the gill faces). Naming and related species The Latin species name, ''querceus'', means "relating to oak", and refers to its being found co ...

Max Britzelmayr
Max Britzelmayr (7 January 1839 – 6 December 1909) was a German mycologist and lichenologist who was a native of Augsburg. He spent his career as a schoolteacher and ''Kreisschulinspektor'' (school district administrator) in Augsburg. He is known for his research of a class of fungi known as Hymenomycetes. He also conducted investigations of lichens native to southern Bavaria, including the Allgäu Alps.

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Marasmius
''Marasmius'' is a genus of mushroom-forming fungi in the family Marasmiaceae. It contains about 500 species of agarics, of which a few, such as '' Marasmius oreades'', are edible. However, most members of this genus are small, unimpressive brown mushrooms. Their humble appearance contributes to their not being readily distinguishable to non-specialists, and they are therefore seldom collected by mushroom hunters. Several of the species are known to grow in the characteristic fairy ring pattern. The author of the genus was Elias Magnus Fries, who in 1838 classified white-spored agarics having a tough central stipe in this taxon if they were marcescent, i.e. they could dry out but later revive when moistened. For Fries, marcescence — by contrast with the " putrescent" (decomposing) nature of most mushrooms — was an important character for classification, which he used to separate this group from genus '' Collybia'' (which has now been split into many newer gen ...

Stipe (botany)
In botany, a stipe is a stalk that supports some other structure. The precise meaning is different depending on which taxonomic group is being described. file:Helicteres-Yucatán-Flowers.jpg, The long stipe of a '' Helicteres'' flower. file:Helicteres-Yucatán-Fruits.jpg, remains as each flower forms a fruit. In the case of ferns, the stipe is only the petiole from the rootstock to the beginning of the leaf tissue, or lamina. The continuation of the structure within the lamina is then termed a rachis. In flowering plants, the term is often used in reference to a stalk that sometimes supports a flower's ovary. In orchids, the stipe or caudicle is the stalk-like support of the pollinia. It is a non-viscid band or strap connecting the pollinia with the viscidium (the viscid part of the rostellum or beak). A stipe is also a structure found in organisms that are studied by botanists but that are no longer classified as plants. It may be the stem-like part of the thallus of a mus ...

Hygrophanous
The adjective hygrophanous refers to the color change of mushroom tissue (especially the pileus surface) as it loses or absorbs water, which causes the pileipellis to become more transparent when wet and opaque when dry. When identifying hygrophanous species, one needs to be careful when matching colors to photographs or descriptions, as color can change dramatically soon after picking. Genera that are characterized by hygrophanous species include ''Agrocybe'', ''Psathyrella'', ''Psilocybe'', ''Panaeolus'', and ''Galerina''.

Pruinose
Pruinescence , or pruinosity, is a "frosted" or dusty-looking coating on top of a surface. It may also be called a pruina (plural: ''pruinae''), from the Latin word for hoarfrost. The adjectival form is pruinose . Entomology In insects, a "bloom" caused by wax particles on top of an insect's cuticle covers up the underlying coloration, giving a dusty or frosted appearance. The pruinescence is commonly white to pale blue in color but can be gray, pink, purple, or red; these colors may be produced by Tyndall scattering of light. When pale in color, pruinescence often strongly reflects ultraviolet. Pruinescence is found in many species of Odonata, particularly damselflies of the families Lestidae and Coenagrionidae, where it occurs on the wings and body. Among true dragonflies it is most common on male Libellulidae (skimmers). In the common whitetail and blue dasher dragonflies (''Plathemis lydia'' and ''Pachydiplax longipennis''), males display the pruinescence on the back of th ...

Mycetinis Scorodonius
''Mycetinis scorodonius'' ( syn. ''Marasmius scorodonius'') is one of the garlic-scented mushrooms formerly in the genus ''Marasmius'', having a beige cap of up to 3 cm and a tough slender stipe. Description The species can be described as follows: *The cap is red brown (or sometimes beige to ochre) and is hygrophanous, drying to a paler colour. It is sometimes slightly wrinkled and grows to 1–3 cm in diameter. *The gills are white and fairly crowded, and the attachment to the stem varies from adnate to almost free. The spore powder is white. *The stem can grow to 6 cm tall but is only up to 2 mm in diameter. It is bald and pale at the apex, reddish brown lower down, and dark brown or blackish at the base. *The smell and taste are strongly of garlic. *The spores are roughly ellipsoid and measure 7–11 µm x 3–5 µm. *The cheilocystidia (on the gill edge) are of the "broom cell" type, that is, they are club-shaped with a number of finger- ...

Cheilocystidia
A cystidium (plural cystidia) is a relatively large cell found on the sporocarp of a basidiomycete (for example, on the surface of a mushroom gill), often between clusters of basidia. Since cystidia have highly varied and distinct shapes that are often unique to a particular species or genus, they are a useful micromorphological characteristic in the identification of basidiomycetes. In general, the adaptive significance of cystidia is not well understood. Classification of cystidia By position Cystidia may occur on the edge of a lamella (or analogous hymenophoral structure) (cheilocystidia), on the face of a lamella (pleurocystidia), on the surface of the cap (dermatocystidia or pileocystidia), on the margin of the cap (circumcystidia) or on the stipe (caulocystidia). Especially the pleurocystidia and cheilocystidia are important for identification within many genera. Sometimes the cheilocystidia give the gill edge a distinct colour which is visible to the naked eye or wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mycetinis
''Mycetinis'' is a genus of fungus in the Omphalotaceae family, containing about eight species formerly classified in ''Marasmius''. General This group of mushrooms was long known as a section (''Alliacei'') within the more familiar genus ''Marasmius'', which means that each of the species has a synonym under ''Marasmius''. They are distinguished from other ''Marasmius'' by the hymeniform cap skin which consists of smooth cells, with hyphae which do not show a dextrinoid reaction. The species have a characteristic garlic smell. DNA studies showed that the group is phylogenetically allied more to genus ''Gymnopus'' than to ''Marasmius'', but the distinct structure of the cap skin is thought to justify a separation at the genus level. Franklin Sumner Earle had already defined the genus name ''Mycetinis'' for this group in 1909, though it had not caught on, and in 2005 Wilson & Desjardin proposed to resurrect this name and redefine it for the current taxonomy.

Elias Magnus Fries
Elias Magnus Fries (15 August 1794 – 8 February 1878) was a Swedish mycologist and botanist. Career Fries was born at Femsjö (Hylte Municipality), Småland, the son of the pastor there. He attended school in Växjö. He acquired an extensive knowledge of flowering plants from his father. In 1811 Fries entered Lund University where he obtained a doctorate in 1814. In the same year he was appointed an associate professorship in botany. He was elected a member of the Royal Swedish Academy of Sciences, and in 1824, became a full professor. In 1834 he became Borgström professor (Swed. ''Borgströmianska professuren'', a chair endowed by Erik Eriksson Borgström, 1708–1770) in applied economics at Uppsala University. The position was changed to "professor of botany and applied economics" in 1851. He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1849. That year he was also appointed director of the Uppsala University Botanica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
