Lepiota Viridigleba
''Lepiota viridigleba'' is a species of sequestrate fungus in the family Agaricaceae. It was first described as new to science by mycologist Michael Castellano in 1995, based on collections made among ''Populus'' roots in California. The fungus was initially called ''Amogaster viridiglebus'' and tentatively placed in the order Boletales. Molecular analysis revealed the fungus to be a member of the genus ''Lepiota ''Lepiota'' is a genus of gilled mushrooms in the family Agaricaceae. All ''Lepiota'' species are ground-dwelling saprotrophs with a preference for rich, calcareous soils. Basidiocarps (fruit bodies) are agaricoid with whitish spores, typically ...'', and it was transferred to that genus in 2013.

Secotioid
Secotioid fungi are an intermediate growth form between mushroom-like hymenomycetes and closed bag-shaped gasteromycetes, where an evolutionary process of gasteromycetation has started but not run to completion. Secotioid fungi may or may not have opening caps, but in any case they often lack the vertical geotropic orientation of the hymenophore needed to allow the spores to be dispersed by wind, and the basidiospores are not forcibly discharged or otherwise prevented from being dispersed (e.g. gills completely inclosed and never exposed as in the secotioid form of ''Lentinus tigrinus'')—note—some mycologists do not consider a species to be secotioid unless it has lost ballistospory. Explanation of secotioid development and gasteromycetation Historically agarics and boletes (which bear their spores on a hymenium of gills or tubes respectively) were classified quite separately from the gasteroid fungi, such as puff-balls and truffles, of which the spores are formed in a l ...

Agaricaceae
The Agaricaceae are a family of basidiomycete fungi and include the genus ''Agaricus'', as well as basidiomycetes previously classified in the families Tulostomataceae, Lepiotaceae, and Lycoperdaceae. Taxonomy The family Agaricaceae was published by French botanist François Fulgis Chevallier in 1826. It is named after the type genus '' Agaricus'', originally circumscribed by Carl Linnaeus in his 1753 work ''Species Plantarum''. In his authoritative 1986 classification of the Agaricales, Rolf Singer divided the Agaricaceae into four tribes distinguished largely by spore color: ''Leucocoprineae'', ''Agariceae'', ''Lepioteae'', and ''Cystodermateae''. Genera once classified in the families Tulostomataceae, Battarreaceae, Lycoperdaceae, and Mycenastraceae have since been moved to the Agaricaceae based on molecular phylogenetics studies. According to a standard reference text, the Agaricaceae contains 85 genera and 1340 species. Description Agaricaceae species use a wide variety ...

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] |
Populus
''Populus'' is a genus of 25–30 species of deciduous flowering plants in the family Salicaceae, native to most of the Northern Hemisphere. English names variously applied to different species include poplar (), aspen, and cottonwood. The western balsam poplar (''Populus trichocarpa, P. trichocarpa'') was the first tree to have its full DNA code determined by DNA sequencing, in 2006. Description The genus has a large genetic diversity, and can grow from tall, with trunks up to in diameter. The Bark (botany), bark on young trees is smooth, white to greenish or dark gray, and often has conspicuous lenticels; on old trees, it remains smooth in some species, but becomes rough and deeply fissured in others. The shoots are stout, with (unlike in the related willows) the terminal bud present. The leaves are spirally arranged, and vary in shape from triangular to circular or (rarely) lobed, and with a long petiole (botany), petiole; in species in the sections ''Populus'' and ''A ...

Boletales
The Boletales are an order of Agaricomycetes containing over 1300 species with a diverse array of fruiting body types. The boletes are the best known members of this group, and until recently, the Boletales were thought to only contain boletes. The Boletales are now known to contain distinct groups of agarics, puffballs, and other fruiting-body types. Taxonomy The order Boletales originally was created to describe boletes, but based on micromorphological and molecular phylogenetic characteristics, a large number of nonbolete species have recently been reclassified to belong to this group, as well. The order also includes some gilled mushrooms, in the families Gomphidiaceae, Serpulaceae, Tapinellaceae, Hygrophoropsidaceae, and Paxillaceae, which often have the same flesh texture as the boletes, spore-bearing tissue which is also easily separable from the cap, and similar microscopic characteristics of spores and cystidia.

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree. History The theoretical ...

Lepiota
''Lepiota'' is a genus of gilled mushrooms in the family Agaricaceae. All ''Lepiota'' species are ground-dwelling saprotrophs with a preference for rich, calcareous soils. Basidiocarps (fruit bodies) are agaricoid with whitish spores, typically with scaly caps and a ring on the stipe. Around 400 species of ''Lepiota'' are currently recognized worldwide. Many species are poisonous, some lethally so. Taxonomy History ''Agaricus'' section ''Lepiota'' was originally published in 1797 by South African-born mycologist Christian Hendrik Persoon. It was subsequently raised to the rank of genus by Samuel Frederick Gray. As originally conceived, the genus was a mix of agarics with rings on their stems, including species now placed in ''Armillaria'', ''Cortinarius'', and ''Pholiota''. In 1822, however, the influential Swedish mycologist Elias Magnus Fries restricted ''Lepiota'' to white-spored, ringed agarics. Based on macro- and micromorphology, later authors gradually refined the gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mycotaxon
''Mycotaxon'' is a peer-reviewed scientific journal that covers the nomenclature and taxonomy of fungi, including lichens. The journal was founded by Grégoire L. Hennebert and Richard P. Korf in 1974. They were frustrated that papers submitted to journals such as ''Mycologia'' took a year or longer from submission to publication. Korf and Hennebert introduced a number of innovations to make their journal more efficient and accessible than its contemporaries. ''Mycotaxon'' reduced the wait time between submission and publication by requiring authors to submit camera-ready copy. Linotype was the industry standard at the time; ''Mycotaxon'' used photo-offset lithography Lithography () is a planographic method of printing originally based on the immiscibility of oil and water. The printing is from a stone ( lithographic limestone) or a metal plate with a smooth surface. It was invented in 1796 by the German ... to expedite publication.

Fungi Described In 1995
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 fungi' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
