Fomes
''Fomes'' is a genus of perennial woody fungi in the family Polyporaceae. Species are typically hoof-shaped (ungulate). New growth each season is added to the margin, resulting in a downward extension of the hymenium. This often results in a zonate appearance of the upper surface, that is, marked by concentric bands of color. The name comes from Latin ''fomes'', meaning "tinder", from the use of ''Fomes fomentarius'', also known as the tinder fungus, in making tinder (see amadou). Taxonomy ''Fomes'' was first introduced by Elias Magnus Fries as a subgenus of ''Polyporus'' in his 1836 work ''Genera Hymenomycetum''. He promoted it to generic status in 1849. Description ''Fomes'' species have perennial, hoof-shaped fruit bodies that attach directly to their substrate without a stipe. The cap surface has a hard smooth crust that ranges in colour from gray to blackish. On the underside of the cap, the pore surface is pale brown with small pores, and brown tube layers. The toug ...

Fomes Fomentarius
''Fomes fomentarius'' (commonly known as the tinder fungus, false tinder fungus, hoof fungus, tinder conk, tinder polypore or ice man fungus) is a species of fungal plant pathogen found in Europe, Asia, Africa and North America. The species produces very large polypore fruit bodies which are shaped like a horse's hoof and vary in colour from a silvery grey to almost black, though they are normally brown. It grows on the side of various species of tree, which it infects through broken bark, causing rot. The species typically continues to live on trees long after they have died, changing from a parasite to a decomposer. Though inedible, ''F. fomentarius'' has traditionally seen use as the main ingredient of amadou, a material used primarily as tinder, but also used to make clothing and other items. The 5,000-year-old Ötzi the Iceman carried four pieces of ''F. fomentarius'', concluded to be for use as tinder. It also has medicinal and other uses. The species is both a p ...

Amadou
Amadou is a spongy material derived from ''Fomes fomentarius'' and similar fungi that grow on the bark of coniferous and angiosperm trees, and have the appearance of a horse's hoof (thus the name "hoof fungus"). It is also known as the "tinder fungus" and is useful for starting slow-burning fires. The fungus must be removed from the tree, the hard outer layer scraped off, and then thin strips of the inner spongy layer cut for use as tinder. Amadou was a precious resource to ancient people, allowing them to start a fire by catching sparks from flint struck against iron pyrites. Bits of fungus preserved in peat have been discovered at the Mesolithic site of Star Carr in the UK, modified presumably for this purpose. Remarkable evidence for its utility is provided by the discovery of the 5,000-year-old remains of "Ötzi the Iceman", who carried it on a cross-alpine excursion before his death and subsequent ice-entombment. Amadou has great water-absorbing abilities. It is used in fly f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyporaceae
The Polyporaceae are a family of poroid fungi belonging to the Basidiomycota. The flesh of their fruit bodies varies from soft (as in the case of the dryad's saddle illustrated) to very tough. Most members of this family have their hymenium (fertile layer) in vertical pores on the underside of the caps, but some of them have gills (e.g. ''Panus'') or gill-like structures (such as ''Daedaleopsis'', whose elongated pores form a corky labyrinth). Many species are brackets, but others have a definite stipe – for example, '' Polyporus badius''. Most of these fungi have white spore powder but members of the genus '' Abundisporus'' have colored spores and produce yellowish spore prints. Cystidia are absent. Taxonomy In his 1838 work ''Epicrisis Systematis Mycologici seu Synopsis Hymenomycetum'', Elias Magnus Fries introduced the "Polyporei". August Corda published the name validly the following year, retaining Fries's concept. American mycologist William Alphonso Murrill, ...

Polyporus
''Polyporus'' is a genus of poroid fungi in the family Polyporaceae. Taxonomy Italian botanist Pier Antonio Micheli introduced the genus in 1729 to include 14 species featuring fruit bodies with centrally-placed stipes, and pores on the underside of the cap. The generic name combines the Ancient Greek words ("many") and ("pore"). Elias Fries divided ''Polyporus'' into three subgenera in his 1855 work ''Novae Symbol Mycologici'': ''Eupolyporus'', ''Fomes'', and ''Poria''. In a 1995 monograph, Maria Núñez and Leif Ryvarden grouped 32 ''Polyporus'' species into 6 morphologically-based infrageneric groups: ''Admirabilis'', ''Dendropolyporus'', ''Favolus'', ''Polyporellus'', ''Melanopus'', and ''Polyporus'' ''sensu stricto''. The identity of the type species of ''Polyporus'' has long been a matter of contention among mycologists. Some have preferred '' P. brumalis'', some '' P. squamosus'', while others have preferred '' P. tuberaster''. Several molecular phylo ...

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] |
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 membrane. The S ...

Microscope Slide
A microscope slide is a thin flat piece of glass, typically 75 by 26 mm (3 by 1 inches) and about 1 mm thick, used to hold objects for examination under a microscope. Typically the object is mounted (secured) on the slide, and then both are inserted together in the microscope for viewing. This arrangement allows several slide-mounted objects to be quickly inserted and removed from the microscope, labeled, transported, and stored in appropriate slide cases or folders etc. Microscope slides are often used together with a cover slip or cover glass, a smaller and thinner sheet of glass that is placed over the specimen. Slides are held in place on the microscope's stage by slide clips, slide clamps or a cross-table which is used to achieve precise, remote movement of the slide upon the microscope's stage (such as in an automated/computer operated system, or where touching the slide with fingers is inappropriate either due to the risk of contamination or lack of precision ...

Potassium Hydroxide
Potassium hydroxide is an inorganic compound with the formula K OH, and is commonly called caustic potash. Along with sodium hydroxide (NaOH), KOH is a prototypical strong base. It has many industrial and niche applications, most of which exploit its caustic nature and its reactivity toward acids. An estimated 700,000 to 800,000 tonnes were produced in 2005. KOH is noteworthy as the precursor to most soft and liquid soaps, as well as numerous potassium-containing chemicals. It is a white solid that is dangerously corrosive. Properties and structure KOH exhibits high thermal stability. Because of this high stability and relatively low melting point, it is often melt-cast as pellets or rods, forms that have low surface area and convenient handling properties. These pellets become tacky in air because KOH is hygroscopic. Most commercial samples are ca. 90% pure, the remainder being water and carbonates. Its dissolution in water is strongly exothermic. Concentrated aqueous solut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basidia
A basidium () is a microscopic sporangium (a spore-producing structure) found on the hymenophore of fruiting bodies of basidiomycete fungi which are also called tertiary mycelium, developed from secondary mycelium. Tertiary mycelium is highly-coiled secondary myceliuma dikaryon. The presence of basidia is one of the main characteristic features of the Basidiomycota. A basidium usually bears four sexual spores called basidiospores; occasionally the number may be two or even eight. In a typical basidium, each basidiospore is borne at the tip of a narrow prong or horn called a sterigma (), and is forcibly discharged upon maturity. The word ''basidium'' literally means "little pedestal", from the way in which the basidium supports the spores. However, some biologists suggest that the structure more closely resembles a club. An immature basidium is known as a basidiole. Structure Most basidiomycota have single celled basidia (holobasidia), but in some groups basidia can be multice ...
