Coccobotrys (fungus)
''Leucoagaricus'' is a genus of fungi in the family Agaricaceae. Several fungus-growing ants cultivate multiple species for food. The genus contains approximately 90 species. Taxonomy This group of mushrooms was first defined as a subgenus of ''Leucocoprinus'' by Marcel Locquin in 1945, and it was then elevated to the status of genus by Rolf Singer in the journal ''Sydowia'' in 1948. The group was characterized as belonging to family Agaricaceae with white, dirty cream or pink spores which are generally small (up to 10 µm) but much bigger in one species, with a germ pore, with a pseudo-amyloid multilayered membrane, simple or ornamented, which is metachromatic in cresyl blue. The hyphae in the sporocarp are without clamp connections. There is always a ring which is initially fixed (but later may be movable). The type species is ''Leucoagaricus barssii'' (Zeller) Vellinga, which was formerly called ''L. macrorhizus''. Species Select species include: *''Leucoagaricus ...

Marcel Locquin
Marcel Locquin, born May 6, 1922, in Lyon, France, died March 18, 2009, was a French mycologist. Locquin rose to eminence in the field of mycology over several years of work with a number of Nobel Prize winners. He himself has won numerous awards. He has worked as consultant for many international organizations. He has filed many patents in light and electron microscopy. Authorship Locquin was a prolific writer. He authored 60 books.

Leucoagaricus Leucothites
''Leucoagaricus leucothites'', the white dapperling, or white Agaricus mushroom, is a species of agaric fungus. The species was originally described as ''Agaricus leucothites'' by Carlo Vittadini in 1835, and bears similarity to species of Agaricus, that genus. Solomon Wasser transferred it to ''Leucoagaricus'' in 1977. While sometimes regarded as edible, the species is suspected of being poisonous due to Indigestion, gastric-upset-causing toxins. It could also be confused with the deadly ''Amanita ocreata''. The mushroom's cap is 4 to 15 cm wide, is granular, white or gray-brown in color then sometimes grayish or pinkish. The flesh may bruise yellowish and the gills reddish. The stipe is 5 to 12 cm long, commonly with a wide base, and bruising yellow or brown. A Annulus (mycology), ring is usually present. The spores are white, smooth, and elliptical. It generally appears in civilized areas such as gardens and parks, but sometimes is found in forests. See also *List of Leucoagar ...

Leucoagaricus Gongylophorus
''Leucoagaricus gongylophorus'' is a fungus in the family Agaricaceae which is cultivated by certain leafcutter ants. Like other species of fungi cultivated by ants, ''L. gongylophorus'' produces gongylidia, nutrient-rich hyphal swellings upon which the ants feed. Production of mushrooms occurs only once ants abandon the nest. ''L. gongylophorus'' is farmed by leaf cutter ant species belonging to the genera ''Atta'' and ''Acromyrmex'', amongst others. Description ''L. gongylophorus'' is completely dependent on ants for survival with workers feeding it cut plant matter and new queens carrying a piece of mycelium in their infrabuccal pocket (a specialised structure within the mouth) in order to found a new colony. For both its source of nutrition and mechanism of spreading it is reliant on the ants. The species has co-evolved with ants so thoroughly that it can no longer rely upon producing mushrooms to emit spores as a viable survival mechanism as it has lost the ...

Leucoagaricus Erythrophaeus
''Leucoagaricus erythrophaeus'' is a species of agaric fungus. Described as new to science in 2010, it is found in California, where it grows in mixed forest. The specific epithet ''erythrophaeus'' originates from the Greek words ερυ𝛉ρος ("red" or "bloody") and ϕαιος ("dark"), and refers to the mushroom's characteristic bruising reaction. The species was formerly known under the misapplied name ''Lepiota roseifolia''. Similar species ''Leucoagaricus badhamii ''Leucoagaricus badhamii'' is a species of fungus in the family Agaricaceae.

Leucoagaricus Badhamii
''Leucoagaricus badhamii'' is a species of fungus in the family Agaricaceae. The flesh of this mushroom turns blood red when cut or bruised, hence its common name of blushing dapperling. These damaged areas may eventually turn brown or black and likewise the mushroom may discolour brown or black with age. All parts of the flesh display red staining aiding in identification. Taxonomy This mushroom was first described by the British mycologists Miles Joseph Berkeley and Christopher Edmund Broome in 1854 who gave it the name ''Agaricus badhamii''. In 1943 the French mycologist Marcel Locquin moved this species to the genus ''Leucocoprinus'' and some modern sources still refer to it as ''Leucocoprinus badhamii'' however in 1951 it was reclassified as a ''Leucoagaricus'' species by the German mycologist Rolf Singer. Etymology ''Leucoagaricus'' gets its name from the Greek ''Leucos'' meaning white and Latin or Greek ''Agaricus'' meaning 'of the country'. ''Badhamii'' is named for th ...

Annulus (mycology)
An annulus is the ring-like or collar-like structure sometimes found on the stipe of some species of mushrooms. The annulus represents the remnants of the partial veil, after it has ruptured to expose the gills or other spore-producing surface. It can also be called a ring which is what the Latin word annulus directly translates as. The modern usage of the Latin word originates from the early days of botany and mycology when species descriptions were only written in Latin. Outside of the formal setting of scientific publications which still have a Latin requirement, it will often just be referred to as a ring or stem ring in field guide A field guide is a book designed to help the reader identify wildlife (flora or fauna) or other objects of natural occurrence (e.g. rocks and minerals).

Clamp Connections
A clamp connection is a hook-like structure formed by growing hyphal cells of certain fungi. It is a characteristic feature of Basidiomycetes fungi. It is created to ensure that each cell, or segment of hypha separated by septa (cross walls), receives a set of differing nuclei, which are obtained through mating of hyphae of differing sexual types. It is used to maintain genetic variation within the hypha much like the mechanisms found in crozier (hook) during sexual reproduction. Formation Clamp connections are formed by the terminal hypha during elongation. Before the clamp connection is formed this terminal segment contains two nuclei. Once the terminal segment is long enough it begins to form the clamp connection. At the same time, each nucleus undergoes mitotic division to produce two daughter nuclei. As the clamp continues to develop it uptakes one of the daughter (green circle) nuclei and separates it from its sister nucleus. While this is occurring the remaining nuclei (or ...

Sporocarp (fungi)
The sporocarp (also known as fruiting body, fruit body or fruitbody) of fungi is a multicellular structure on which spore-producing structures, such as basidia or asci, are borne. The fruitbody is part of the sexual phase of a fungal life cycle, while the rest of the life cycle is characterized by vegetative mycelial growth and asexual spore production. The sporocarp of a basidiomycete is known as a ''basidiocarp'' or ''basidiome'', while the fruitbody of an ascomycete is known as an '' ascocarp''. Many shapes and morphologies are found in both basidiocarps and ascocarps; these features play an important role in the identification and taxonomy of fungi. Fruitbodies are termed ''epigeous'' if they grow on the ground, while those that grow underground are '' hypogeous''. Epigeous sporocarps that are visible to the naked eye, especially fruitbodies of a more or less agaricoid morphology, are often called mushrooms. Epigeous sporocarps have mycelia that extend undergroun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypha
A hypha (; ) is a long, branching, filamentous structure of a fungus, oomycete, or actinobacterium. In most fungi, hyphae are the main mode of vegetative growth, and are collectively called a mycelium. Structure A hypha consists of one or more cells surrounded by a tubular cell wall. In most fungi, hyphae are divided into cells by internal cross-walls called "septa" (singular septum). Septa are usually perforated by pores large enough for ribosomes, mitochondria, and sometimes nuclei to flow between cells. The major structural polymer in fungal cell walls is typically chitin, in contrast to plants and oomycetes that have cellulosic cell walls. Some fungi have aseptate hyphae, meaning their hyphae are not partitioned by septa. Hyphae have an average diameter of 4–6 µm. Growth Hyphae grow at their tips. During tip growth, cell walls are extended by the external assembly and polymerization of cell wall components, and the internal production of new cell membran ...
