Pleurotus Smithii
''Pleurotus smithii'' is a species of fungus in the family Pleurotaceae, described as new to science by mycologist Gastón Guzmán in 1975.Guzmán, G. (1975) , In: Beih. Nova Hedwigia 55:100. Like other species of the '' Pleurotus cystidiosus'' clade, it has an anamorphic form, named ''Antromycopsis guzmanii''. ''P. smithii'' can be distinguished from ''P. cystidiosus'' by lack of pleurocystidia or them being only present in young stages as cystidioid elements, short hyphal segments of the conidiophores in the anamorph, and long subcylindrical 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 ar ... in the teleomorph form.

Gastón Guzmán
Gastón Guzmán Huerta (August 26, 1932 – January 12, 2016), a Mexican mycologist and anthropologist, was an authority on the genus ''Psilocybe''. Career He was born in Xalapa, Veracruz, in 1932. His interest in mycology began in 1955 when as a graduate student he decided to update his school's (National Polytechnic Institute) poorly kept collection of fungi. During his early field work he found a large assortment of species about which little was known at the time. This inspired him to choose fungi as the topic of his professional thesis. In 1957 Guzmán was invited by the University of Mexico to assist Rolf Singer, who would arrive to Mexico the following year to study the hallucinogenic mushroom genus ''Psilocybe''. Guzmán accepted and assisted Singer through his explorations in Mexico. While they were in the Huautla de Jiménez region, in their last day of the expeditions, they met R. Gordon Wasson. For Guzmán it was a "fructiferous meeting." In 1958, he published his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungus
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleurotaceae
The Pleurotaceae are a family of small to medium-sized mushrooms which have white spores. The family contains four genera ('' Nematoctonus'' has been synonymized with '' Hohenbuehelia'', but not all of its species have been moved to valid genera) and 94 species. Members of Pleurotaceae can be mistaken for members of Marasmiaceae. Perhaps the best known member is the oyster mushroom, ''Pleurotus ostreatus''. Many species in the genera '' Pleurotus'' and '' Hohenbuehelia'' are nematophagous, that is, they derive nutrition by consuming nematodes. This is made possible by hyphae 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.

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] |
Pleurotus Cystidiosus
''Pleurotus cystidiosus'', also known as abalone mushroom and maple oyster mushroom, is an edible species of fungus in the family Pleurotaceae, described as new to science by mycologist Orson K. Miller Jr. in 1969. It can be cultivated, with spores and growing kits being available commercially. ''Antromycopsis macrocarpa'' (or ''A. broussonetiae'') is the anamorphic Anamorphic format is the cinematography technique of shooting a widescreen picture on standard 35 mm film or other visual recording media with a non-widescreen native aspect ratio.

Teleomorph, Anamorph And Holomorph
In mycology, the terms teleomorph, anamorph, and holomorph apply to portions of the life cycles of fungi in the phyla Ascomycota and Basidiomycota: *Teleomorph: the sexual reproductive stage (morph), typically a fruiting body. *Anamorph: an asexual reproductive stage (morph), often mold-like. When a single fungus produces multiple morphologically distinct anamorphs, these are called synanamorphs. *Holomorph: the whole fungus, including anamorphs and teleomorph. Dual naming of fungi Fungi are classified primarily based on the structures associated with sexual reproduction, which tend to be evolutionarily conserved. However, many fungi reproduce only asexually, and cannot easily be classified based on sexual characteristics; some produce both asexual and sexual states. These problematic species are often members of the Ascomycota, but a few of them belong to the Basidiomycota. Even among fungi that reproduce both sexually and asexually, often only one method of reproduction can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pleurocystidia
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] |
Conidiophores
A conidium ( ; ), sometimes termed an asexual chlamydospore or chlamydoconidium (), is an Asexual reproduction, asexual, non-motility, motile spore of a fungus. The word ''conidium'' comes from the Ancient Greek word for dust, ('). They are also called mitospores due to the way they are generated through the cellular process of mitosis. The two new haploid cells are genetically identical to the haploid parent, and can develop into new organisms if conditions are favorable, and serve in biological dispersal. Asexual reproduction in ascomycetes (the phylum Ascomycota) is by the formation of conidia, which are borne on specialized stalks called conidiophores. The Morphology (biology), morphology of these specialized conidiophores is often distinctive between species and, before the development of molecular techniques at the end of the 20th century, was widely used for identification of (''e.g.'' ''Metarhizium#Species, Metarhizium'') species.
