Mycena Silvaelucens
''Mycena'' is a genus of about 500 species of fungi. Rarely more than a few centimeters in width, the mushrooms are characterized by a small conical or bell-shaped cap and a thin fragile stem. Most are grey or brown, but a few species have brighter colours. Most have a translucent and striate cap, which rarely has an incurved margin. The gills are attached and usually have cystidia. Some species, like '' M. haematopus'', exude a latex when the stem is broken, and many species have a chlorine or radish-like odour. They produce a white spore print. The species are saprotrophic. Their edibility varies, with some members containing toxins. Taxonomy ''Mycena'' is a rich genus, considered one of the most abundant genera of mushrooms within the Agaricales and with species distributed across the world. Alexander Smith's 1947 ''Mycena'' monograph identified 232 species; the genus is now known to include about 500 species worldwide. Maas Geesteranus divided the genus into 3 ...

Mycena Amicta
''Mycena amicta'', commonly known as the coldfoot bonnet, is a species of mushroom in the family Mycenaceae. It was first described in 1821 by mycologist Elias Magnus Fries. Description Young specimens appear unmistakably blue; this fades to brownish hues in age. The pileus (mycology), cap, initially conical to convex in shape, flattens out with age and typically reaches diameters of up to . The cap cuticle can be peeled. The gills are close and the stem is covered in powdery hairs. Similar species It can resemble ''Mycena subcaerulea, M. subcaerulea'' and ''Psilocybe pelliculosa''. Habitat and distribution The mushrooms appear in small groups, on the trunks of broadleaved trees, and particularly in the Pacific Northwest, around rotted conifer wood. It appears from May to November on the West Coast, July–September further east. References {{Taxonbar, from=Q10495970 Mycena, amicta Fungi described in 1821 Fungi of Europe Fungus species ...

Edible Mushroom
Edible mushrooms are the fleshy fruit bodies of numerous species of macrofungi (fungi that bear fruiting structures large enough to be seen with the naked eye). Edibility may be defined by criteria including the absence of poisonous effects on humans and desirable taste and aroma. Mushrooms that have a particularly desirable taste are described as "''choice''". Edible mushrooms are consumed for their nutritional and culinary value. Mushrooms, especially dried shiitake, are sources of umami flavor. To ensure safety, wild mushrooms must be correctly identified before their edibility can be assumed. Deadly poisonous mushrooms that are frequently confused with edible mushrooms include several species of the genus ''Amanita'', particularly '' A. phalloides'', the death cap. Some mushrooms that are edible for most people can cause allergic reactions in others; old or improperly stored specimens can go rancid and cause food poisoning. Additionally, mushrooms can absor ...

Mycena Aetites
''Mycena aetites'', commonly known as the drab bonnet, is a species of mushroom in the family Mycenaceae. First described as ''Agaricus aetites'' by Swedish mycologist Elias Magnus Fries in 1838, it was assigned its current name in 1872 by Lucien Quélet. This rare mushroom is found in Europe. Description The cap A cap is a flat headgear, usually with a visor. Caps have crowns that fit very close to the head. They made their first appearance as early as 3200 BC. The origin of the word "cap" comes from the Old French word "chapeau" which means "head co ... is a grey-brown color that is somewhat darker in the center. Initially conical in shape, the cap flattens out in maturity to become bell-shaped; the cap can reach a diameter of up to . The stipe of ''M. aetites'' has a pruinose apex and isglabrous below. The mushrooms has an raphanoid odour. A similar species is '' Mycena abramsii''. This species usually grows on woods and have cheilocystidia with a clear acute-neck. ...

Mycena Adscendens
''Mycena adscendens'', commonly known as the frosty bonnet, is a species of fungus in the family Mycenaceae. The fungus produces small white fruit bodies (mushrooms) with caps up to in diameter that appear to be dusted with sugar-like granules. Caps are supported by thin, hollow stems up to long, which are set on a disc-like base. Its distribution includes Europe, Turkey and the Pacific coast of the United States. The fruit bodies grow on fallen twigs and other woody debris on the forest floor, including fallen hazel nuts. The variety ''carpophila'' is known from Japan. There are several small white '' Mycena'' species that are similar in appearance to ''M. adscendens'', some of which can be reliably distinguished only by examining microscopic characteristics. Taxonomy The species, originally named ''Agaricus adscendens'' by Wilhelm Gottfried Lasch in 1829, was first collected in the Province of Brandenburg, in what was then the Kingdom of Prussia (now Germany). ...

Mycena Adonis
''Atheniella adonis'', which has the recommended name of scarlet bonnet in the UK, is a species of agaric in the family Cyphellaceae.It produces small orangish to reddish mushrooms with pileus (mycology), caps up to in diameter and thin pinkish-white stipe (mycology), stems reaching long. The fungus typically grows in conifer woods in Eurasia and North America. Taxonomy The species was first named ''Agaricus adonis'' in 1792 by Jean Baptiste François Pierre Bulliard, and placed in ''Mycena'' by Samuel Frederick Gray in 1821. Rolf Singer successively moved it to ''Hemimycena'' (1943), then ''Marasmiellus'' (1951). Singer later changed his mind about these placements, in 1986 considering the species a ''Mycena''. Recent Molecular phylogenetics, molecular research, based on cladistic analysis of DNA sequences, has shown that the species is not closely related to ''Mycena'' and belongs in the Cyphellaceae in the genus ''Atheniella''. Etymology The species epithet refers to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycena Acicula
''Mycena acicula'', commonly known as the orange bonnet, or the coral spring Mycena, is a species of fungus in the family Mycenaceae. The mushrooms have small orange-red caps, up to in diameter, held by slender yellowish stems up to long. The gills are pale yellow with a whitish edge. Several other '' Mycena'' species look similar, but may be distinguished by differences in size and/or microscopic characteristics. The fungus grows on dead twigs and other woody debris of forest floors, especially along streams and other wet places. It is found in Eurasia, North America, and the Caribbean. It considered inedible because of its small size. Taxonomy First named ''Agaricus acicula'' by the German scientist Jacob Christian Schäffer in 1774, the species was also referred to as ''Agaricus miniatus'' by another German, naturalist August Batsch. It was given its current name in 1871 by Paul Kummer. Rolf Singer transferred the species to the genera '' Hemimycena'' and '' Marasm ...

Biological Life Cycle
In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the process repeating in a cyclic fashion. "The concept is closely related to those of the life history, Developmental biology, development and ontogeny, but differs from them in stressing renewal." Transitions of form may involve growth, asexual reproduction, or sexual reproduction. In some organisms, different "generations" of the species succeed each other during the life cycle. For Embryophyte, plants and many algae, there are two multicellular stages, and the life cycle is referred to as alternation of generations. The term life history is often used, particularly for organisms such as the red algae which have three multicellular stages (or mor ...

Taxonomy (biology)
In biology, taxonomy () is the science, scientific study of naming, defining (Circumscription (taxonomy), circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxon, taxa (singular: taxon), and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain (biology), domain, kingdom (biology), kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class (biology), class, order (biology), order, family (biology), family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, having developed a ranked system known as Linnaean taxonomy for categorizing organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transfo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Hemisphere
The Northern Hemisphere is the half of Earth that is north of the equator. For other planets in the Solar System, north is defined by humans as being in the same celestial sphere, celestial hemisphere relative to the invariable plane of the Solar System as Earth's North Pole. Due to Earth's axial tilt of 23.439281°, there is a seasonal variation in the lengths of the day and night. There is also a seasonal variation in temperatures, which lags the variation in day and night. Conventionally, winter in the Northern Hemisphere is taken as the period from the December solstice (typically December 21 UTC) to the March equinox (typically March 20 UTC), while summer is taken as the period from the June solstice through to the September equinox (typically on 23 September UTC). The dates vary each year due to the difference between the calendar year and the Year#Astronomical years, astronomical year. Within the Northern Hemisphere, oceanic currents can change the weather patterns that aff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Section (botany)
In botany, a section () is a taxonomic rank below the genus, but above the species. The subgenus, if present, is higher than the section; and the rank of Series (botany), series, if present, is below the section. Sections may in turn be divided into subsections.Article 4 in Sections are typically used to help organise very large genera, which may have hundreds of species. A botanist wanting to distinguish groups of species may prefer to create a taxon at the rank of section or series to avoid making combinatio nova, new combinations, i.e. many new Binomial nomenclature, binomial names for the species involved. Examples: * ''Lilium'' sectio ''Martagon'' Rchb. are the Turks' cap lilies * ''Plagiochila aerea'' Taylor is the type species of ''Plagiochila'' sect.

Rudolf Arnold Maas Geesteranus
Rudolf Arnold Maas Geesteranus (20 January 1911 in The Hague – 18 May 2003 in Oegstgeest), was a Dutch mycologist whose work on both ascomycetes and basidiomycetes helped to refine fungal taxonomy over a career of nearly six decades. Early life and education Maas Geesteranus was born in The Hague, but spent his childhood (from infancy until age 18) in the Dutch East Indies, where his family emigrated shortly after his birth. Upon returning to the Netherlands in 1929, he completed secondary school in The Hague and enrolled at Leiden University to study biology. While still a student, he joined the staff of the Rijksherbarium (the National Herbarium of the Netherlands) as a volunteer assistant—a post that proved pivotal in launching his scientific career. In mid‑1939, at 28, he was promoted to assistant, becoming the sole mycologist on the herbarium staff at that time. Life and career During the German occupation of the Netherlands in World War II, Maas Geesteranus conti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
