Forest Floor
The forest floor, also called detritus, duff and the O horizon, is one of the most distinctive features of a forest ecosystem. It mainly consists of shed vegetative parts, such as leaves, branches, bark, and stems, existing in various stages of decomposition above the soil surface. Although principally composed of non-living organic material, the forest floor also teems with a wide variety of fauna and flora. It is one of the richest components of the ecosystem from the standpoint of biodiversity because of the large number of decomposers and predators present, mostly belonging to invertebrates, fungi, algae, bacteria, and archaea. Certain (adapted) plants may be more apparent in tropical forests, where rates of metabolism and species diversity are much higher than in colder climates. The major compartments for the storage of organic matter and nutrients within systems are the living vegetation, forest floor, and soil. The forest floor serves as a bridge between the ab ...

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.

Tricholomataceae
The Tricholomataceae are a large family of mushrooms within the Agaricales. Originally a classic "wastebasket taxon", the family included any white-, yellow-, or pink-spored genera in the Agaricales not already classified as belonging to e.g. the Amanitaceae, Lepiotaceae, Hygrophoraceae, Pluteaceae, or Entolomataceae. The name derives from the Greek ''trichos'' (τριχος) meaning hair and ''loma'' (λωμα) meaning fringe or border, although not all members display this feature. The name "Tricholomataceae" is seen as having validity in describing ''Tricholoma'' and its close relatives, and whatever other genera can at some future point be described as part of a monophyletic family including ''Tricholoma''. To that end, the International Botanical Congress has voted on two occasions (1988 and 2006) to conserve the name "Tricholomataceae" against competing names. This decision does not invalidate the use of segregate families from the Tricholomataceae, but simply validates th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elias 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 Botanical G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi
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'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North American Mycological Association
The North American Mycological Association (NAMA), is a non-profit organization of amateurs and professionals who are interested in fungi, including mushrooms, morels, truffles, molds, and related organisms. NAMA aims "to promote, pursue, and advance the science of mycology." Membership Membership is open to all persons interested in fungi, including both professionals and amateurs of any skill level. Publications The official journal of NAMA is ''McIlvainea: The Journal of Amateur Mycology'', which is published bi-annually. NAMA members also receive ''The Mycophile'', NAMA's bi-monthly newsletter. NAMA members also provide educational material for teaching and learning about fungi vitheir website Activities Since 1961, NAMA has sponsored an annual foray, at which members meet to collect and identify mushrooms and other fungi. Each year the foray takes place in a different location in North America. NAMA tracks North American mushroom poisoning cases (of humans and animals), a ...

Cream (colour)
Cream is the colour of the cream produced by cattle grazing on natural pasture with plants rich in yellow carotenoid pigments, some of which are incorporated into the fresh milk (specifically, the butterfat). This gives a yellow tone to otherwise-white milk at higher fat concentrations (so the colour of dairy cream could be considered partway between the colours of natural cow’s milk and butter). Cream is the pastel colour of yellow, much as pink is to red. By mixing yellow and white, cream can be produced. The first recorded use of ''cream'' as a colour name in English was in 1590. In nature ;Birds * The cream-coloured courser * The cream-coloured woodpecker ;Mammals * The cream-coloured giant squirrel In human culture Art * Cream is used as a skin tone in some forms of art, mostly anime. It is also used to describe the general skin tone of East and South East Asia. Clothing * Men's white tuxedo jackets are usually a shade of cream or ivory to better stand out again ...

Lactarius (fungus)
''Lactarius'' is a genus of mushroom-producing, ectomycorrhizal fungi, containing several edible species. The species of the genus, commonly known as milk-caps, are characterized by the milky fluid ("latex") they exude when cut or damaged. Like the closely related genus ''Russula'', their flesh has a distinctive brittle consistency. It is a large genus with over 500 known species, mainly distributed in the Northern hemisphere. Recently, the genus ''Lactifluus'' has been separated from ''Lactarius'' based on molecular phylogenetic evidence. Systematics and taxonomy The genus ''Lactarius'' was described by Christian Hendrik Persoon in 1797 with '' L. piperatus'' as the original type species. In 2011, '' L. torminosus'' was accepted as the new type of the genus after the splitting-off of ''Lactifluus'' as separate genus. The name "''Lactarius''" is derived from the Latin ''lac'', "milk". Placement within Russulaceae Molecular phylogenetics uncovered that, while macromorphologic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russula Virescens
''Russula virescens'' is a basidiomycete mushroom of the genus ''Russula'', and is commonly known as the green-cracking russula, the quilted green russula, or the green brittlegill. It can be recognized by its distinctive pale green cap that measures up to in diameter, the surface of which is covered with darker green angular patches. It has crowded white gills, and a firm, white stipe that is up to tall and thick. Considered to be one of the best edible mushrooms of the genus ''Russula'', it is especially popular in Spain and China. With a taste that is described variously as mild, nutty, fruity, or sweet, it is cooked by grilling, frying, sautéeing, or eaten raw. Mushrooms are rich in carbohydrates and proteins, with a low fat content. The species was described as new to science in 1774 by Jacob Christian Schaeffer. Its distribution encompasses Asia, North Africa, Europe, and Central America. Its presence in North America has not been clarified, due to confusion with t ...

Spore Print ID
In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa. Bacterial spores are not part of a sexual cycle, but are resistant structures used for survival under unfavourable conditions. Myxozoan spores release amoeboid infectious germs ("amoebulae") into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula. In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which eventually goes on to produce gametes. Two gametes fuse to form a zygote which develops into a new sporo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russula Crustosa
''Russula crustosa'', commonly known as the crusty russula, is a species of fungus in the family Russulaceae. It is found in Asia and North America. Taxonomy The species was first described scientifically by American mycologist Charles Horton Peck in 1886, who made the type collections in Day, New York. It is classified in the subsection ''Virescentinae'' of the genus ''Russula''. The specific epithet ''crustosa'' means "with a rind". Common names for the species include "crusty Russula", "green quilt Russula", and "encrusted Russula". Description The fruit bodies have caps that are initially convex before flattening out in age, often developing a central depression, and measure in diameter. In maturity, the dry cap surface breaks up into greenish patches around the margin. The margin of the cap has radial grooves that match the gills on the underside. The closely spaced gills are white, cream, or pale yellow in color, and have an adnate attachment to the stem. Measuring lo ...
