Fistulina Hepatica
''Fistulina hepatica'' (beefsteak fungus, also known as beefsteak polypore, poor man’s steak, ox tongue, or tongue mushroom) is an unusual bracket fungus classified in the Agaricales, that is commonly seen in Britain, but can be found in North America, Australia, North Africa, Southern Africa and the rest of Europe. As its name suggests, it looks remarkably similar to a slab of raw meat. It has been used as a meat substitute in the past, and can still be found in some French markets. It has a sour, slightly acidic taste. For eating it must be collected young and it may be tough and need long cooking. Details The cap is 7–30 cm wide and 2–6 cm thick. Is shape resembles a large tongue, and it is rough-surfaced with a reddish-brown colour. The spores are pink and released from minute pores on the creamy-white underside of the fruit body. A younger ''Fistulina hepatica'' is a pinkish-red colour, and it darkens with age. It bleeds a dull red juice when cut, which can caus ...

Gyromitra Esculenta
''Gyromitra esculenta'' is an ascomycete fungus from the genus ''Gyromitra'', widely distributed across Europe and North America. It normally fruits in sandy soils under coniferous trees in spring and early summer. The fruiting body, or mushroom, is an irregular brain-shaped cap dark brown in colour that can reach high and wide, perched on a stout white stipe up to high. Although potentially fatal if eaten raw, ''Gyromitra esculenta'' is a popular delicacy in Scandinavia, Eastern Europe, and the upper Great Lakes region of North America. Although popular in some districts of the eastern Pyrenees, it is prohibited from sale to the public in Spain. It may be sold fresh in Finland, but it must be accompanied by warnings and instructions on correct preparation. Although it is still commonly parboiled before preparation, evidence suggests that even this procedure may not make ''Gyromitra esculenta'' entirely safe for consumption. When consumed, the principal active agent, gy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tubules
In biology, a tubule is a general term referring to small tube or similar type of structure. Specifically, tubule can refer to: * a small tube or fistular structure * a minute tube lined with glandular epithelium * any hollow cylindrical body structure * a minute canal found in various structures or organs of the body * a slender elongated anatomical channel * a minute tube, especially as an anatomical structure. Examples of tubules * Collecting tubules: terminal channels of the nephrons * Cuvierian tubules: clusters of sticky tubules located at the base of the respiratory tree, which may be discharged by some sea cucumbers (holothurians) when mechanically stimulated (i.e. being threatened by a predator) * Dentinal tubules or dental canaliculi: minute channels in the dentine of a tooth that extend from the pulp cavity to the cementum or the enamel * Distal convoluted tubule: the convoluted portion of the vertebrate nephron that lies between the loop of Henle and the nonsecretory ...

Forest Pathology
Forest pathology is the research of both Biotic stress, biotic and Abiotic stress, abiotic maladies affecting the health of a forest ecosystem, primarily Fungal infection in plants, fungal pathogens and their insect vectors. It is a subfield of forestry and plant pathology. Forest pathology is part of the broader approach of forest protection. Insects, diseases and severe weather events damaged about 40 million ha of forests in 2015, mainly in the temperate and boreal domains. Abiotic factors There are a number of Abiotic component, abiotic factors which affect the health of a forest, such as moisture issues like drought, winter-drying, Waterlogging (agriculture), waterlogging resulting from over-abundance or lack of precipitation (meteorology), precipitation such as hail, snow, rain. Wind is also an important abiotic factor as windthrow (the uprooting or breaking of trees due to high winds) causes an obvious and direct loss of stability to a forest or its trees. Often, abio ...

Hymenium
The hymenium is the tissue layer on the hymenophore of a fungal fruiting body where the cells develop into basidia or asci, which produce spores. In some species all of the cells of the hymenium develop into basidia or asci, while in others some cells develop into sterile cells called cystidia (basidiomycetes) or paraphyses (ascomycetes). Cystidia are often important for microscopic identification. The subhymenium consists of the supportive hyphae from which the cells of the hymenium grow, beneath which is the hymenophoral trama, the hyphae that make up the mass of the hymenophore. The position of the hymenium is traditionally the first characteristic used in the classification and identification of mushrooms. Below are some examples of the diverse types which exist among the macroscopic Basidiomycota and Ascomycota. * In agarics, the hymenium is on the vertical faces of the gills. * In boletes and polypores, it is in a spongy mass of downward-pointing tubes. * In puffballs, ...

Gill
A gill () is a respiratory organ that many aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. The microscopic structure of a gill presents a large surface area to the external environment. Branchia (pl. branchiae) is the zoologists' name for gills (from Ancient Greek ). With the exception of some aquatic insects, the filaments and lamellae (folds) contain blood or coelomic fluid, from which gases are exchanged through the thin walls. The blood carries oxygen to other parts of the body. Carbon dioxide passes from the blood through the thin gill tissue into the water. Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including mollusks, crustaceans, insects, fish, and amphibians. Semiterrestrial marine animals such as crabs and mudskippers have gill cham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyphelloid
The cyphelloid fungi are a group of fungi in the Basidiomycota that have disc-, tube-, or cup-shaped basidiocarps (fruit bodies), resembling species of discomycetes (or "cup fungi") in the Ascomycota. They were originally referred to the genus '' Cyphella'' ("cyphelloid" means ''Cyphella''-like) and subsequently to the family Cyphellaceae, but are now known to be much more diverse and are spread through several different genera and families. Since they are often studied as a group, it is convenient to call them by the informal (non-taxonomic) name of "cyphelloid fungi". Better known cyphelloid genera include ''Calyptella'', with stalked, cup- or bell-like fruit bodies; ''Lachnella'', with conspicuous, hairy-margined, disc-like fruit bodies; ''Flagelloscypha'' with smaller, but equally hairy, cup-like fruit bodies; ''Henningsomyces'' with tube-like fruit bodies; and ''Merismodes'' with clustered, hairy, cup-like fruit bodies. History The genus ''Cyphella'' was original described by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Schizophyllaceae
The Schizophyllaceae are a family of fungi in the order Agaricales. The family contains two genera and seven species. Species cause white rot in hardwoods. The most common member of the genus ''Schizophyllum'' is ''Schizophyllum commune'', a widely distributed mushroom. It looks like an oyster mushroom, but is one-fifth the size. See also *List of Agaricales families The Agaricales are an order of fungi in the class Agaricomycetes (division Basidiomycota).

Agaric
An agaric () is a type of fungus fruiting body characterized by the presence of a pileus (cap) that is clearly differentiated from the stipe (stalk), with lamellae (gills) on the underside of the pileus. In the UK, agarics are called "mushrooms" or "toadstools". In North America they are typically called "gilled mushrooms". "Agaric" can also refer to a basidiomycete species characterized by an agaric-type fruiting body. Archaically, agaric meant 'tree-fungus' (after Latin ''agaricum''); however, that changed with the Linnaean interpretation in 1753 when Linnaeus used the generic name ''Agaricus'' for gilled mushrooms. Most species of agaricus belong to the order Agaricales in the subphylum Agaricomycotina. The exceptions, where agarics have evolved independently, feature largely in the orders Russulales, Boletales, Hymenochaetales, and several other groups of basidiomycetes. Old systems of classification placed all agarics in the Agaricales and some (mostly older) sources use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Wood-decay Fungus
A wood-decay or xylophagous fungus is any species of fungus that digests moist wood, causing it to rot. Some species of wood-decay fungi attack dead wood, such as brown rot, and some, such as ''Armillaria'' (honey fungus), are parasitic and colonize living trees. Excessive moisture above the fibre saturation point in wood is required for fungal colonization and proliferation. In nature, this process causes the breakdown of complex molecules and leads to the return of nutrients to the soil. Wood-decay fungi consume wood in various ways; for example, some attack the carbohydrates in wood and some others decay lignin. The rate of decay of wooden materials in various climates can be estimated by empirical models.Viitanen, T. et al. (2010). Towards modelling of decay risk of wooden materials. European Journal of Wood and Wood Products 68:303-313. Wood-decay fungi can be classified according to the type of decay that they cause. The best-known types are brown rot, soft rot, and whit ...
