Hydnoid Fungus
The hydnoid fungi are a group of fungi in the Basidiomycota with basidiocarps (fruit bodies) producing spores on pendant, tooth-like or spine-like projections. They are colloquially called tooth fungi. Originally such fungi were referred to the genus ''Hydnum'' ("hydnoid" means ''Hydnum''-like), but it is now known that not all hydnoid species are closely related. History ''Hydnum'' was one of the original genera created by Linnaeus in his ''Species Plantarum'' of 1753. It contained all species of fungi with fruit bodies bearing pendant, tooth-like projections. Subsequent authors described around 900 species in the genus. With increasing use of the microscope, it became clear that not all tooth fungi were closely related and most ''Hydnum'' species were gradually moved to other genera. The Dutch mycologist Rudolph Arnold Maas Geesteranus paid particular attention to the group, producing a series of papers reviewing the taxonomy of hydnoid fungi. The original genus ''Hydnum'' is st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hymenochaetales
The Hymenochaetales are an order of fungi in the class Agaricomycetes. The order in its current sense is based on molecular research and not on any unifying morphological characteristics. According to one 2008 estimate, the Hymenochaetales contain around 600 species worldwide, mostly corticioid fungi and poroid fungi, but also including several clavarioid fungi and agarics. Species of economic importance include wood decay fungi in the genera '' Phellinus'' and ''Inonotus'' sensu lato, some of which may cause losses in forestry. Therapeutic properties are claimed for ''Inonotus obliquus'' ("chaga") and ''Phellinus linteus'', both of which are now commercially marketed. Taxonomy History The order was proposed in 1977 to recognize the family Hymenochaetaceae at a higher taxonomic rank. As originally conceived, species within the Hymenochaetales had several morphological features in common, notably brown or brownish basidiocarps (fruit bodies) that turn black in alkali, hyphae l ...

Regional Red List
A Regional Red List is a report of the threatened status of species within a certain country or region. It is based on the IUCN Red List of Threatened Species, an inventory of the conservation status of species on a global scale. Regional Red Lists assess the risk of extinction to species within a political management unit and therefore may feed directly into national and regional planning. This project is coordinated by the Zoological Society of London, the World Conservation Union (IUCN) and partners in national governments, universities and organizations throughout the world. Regional Red Lists may assist countries or regions in: * Determining the conservation status and trends of species * Identifying species or ecosystems under greatest threat * Informing conservation planning and priority setting * Raising awareness of threatened species Assessing extinction risk on a regional scale The IUCN Categories and Criteria were initially designed to assess the conservation s ...

Indicator Species
A bioindicator is any species (an indicator species) or group of species whose function, population, or status can reveal the qualitative status of the environment. The most common indicator species are animals. For example, copepods and other small water crustaceans that are present in many water body, water bodies can be monitored for changes (biochemical, physiological, or behavioural) that may indicate a problem within their ecosystem. Bioindicators can tell us about the cumulative effects of different pollution, pollutants in the ecosystem and about how long a problem may have been present, which Water pollution#Measurement, physical and chemical testing cannot. A biological monitor or biomonitor is an organism that provides quantitative property, quantitative information on the quality of Environment (biophysical), the environment around it. Therefore, a good biomonitor will indicate the presence of the pollutant and can also be used in an attempt to provide additional inform ...

Ectomycorrhizal
An ectomycorrhiza (from Greek ἐκτός ', "outside", μύκης ', "fungus", and ῥίζα ', "root"; pl. ectomycorrhizas or ectomycorrhizae, abbreviated EcM) is a form of symbiotic relationship that occurs between a fungal symbiont, or mycobiont, and the roots of various plant species. The mycobiont is often from the phyla Basidiomycota and Ascomycota, and more rarely from the Zygomycota. Ectomycorrhizas form on the roots of around 2% of plant species, usually woody plants, including species from the birch, dipterocarp, myrtle, beech, willow, pine and rose families. Research on ectomycorrhizas is increasingly important in areas such as ecosystem management and restoration, forestry and agriculture. Unlike other mycorrhizal relationships, such as arbuscular mycorrhiza and ericoid mycorrhiza, ectomycorrhizal fungi do not penetrate their host's cell walls. Instead they form an entirely intercellular interface known as the Hartig net, consisting of highly branched hyphae formi ...

Sarcodon
''Sarcodon'' is a genus of fungi in the family Bankeraceae, which is part of the order Thelephorales The Thelephorales are an order of fungi in the class Agaricomycetes. The order includes corticioid and hydnoid fungi, together with a few polypores and clavarioid species. Most fungi within the Thelephorales are ectomycorrhizal. None is of any ... known for its almost universal ectomycorrhizal life style. The genus owes its name to the presence of teeth-like spines on the hymenophore, it is derived from ancient Greek; ''sarco'' = flesh and ''odon'' = tooth. This is why they are commonly called "tooth fungi", or "Hydnoid fungi". Several species of the ''Sarcodon'' genus, including ''Sarcodon imbricatus'' (see figure), are edible. The fungus can be bitter, but that is less apparent in younger specimens. In China, it is a popular edible mushroom and it is used for lowering of cholesterol level, muscles relaxation and blood circulation. Isolates from the genus, called Scabroni ...

Phellodon
''Phellodon'' is a genus of tooth fungi in the family Bankeraceae. Species have small- to medium-sized fruitbodies with white spines on the underside from which spores are released. All ''Phellodon'' have a short stalk or stipe, and so the genus falls into the group known as stipitate hydnoid fungi. The tough and leathery flesh usually has a pleasant, fragrant odor, and develops a cork-like texture when dry. Neighboring fruitbodies can fuse, sometimes producing large mats of joined caps. ''Phellodon'' species produce a white spore print, while the individual spores are roughly spherical to ellipsoid in shape, with spiny surfaces. The genus, with about 20 described species, has a distribution that includes to Asia, Europe, North America, South America, Australia, and New Zealand. About half of the species are found in the southeastern United States, including three species added to the genus in 2013–14. Several ''Phellodon'' species were placed on a preliminary Red List ...

Hydnellum
''Hydnellum'' is a genus of tooth fungi in the family Bankeraceae (order Thelephorales). Widely distributed in the Northern Hemisphere, the genus contains around 40 species. The fruitbodies of its members grow by slowly enveloping nearby bits of grass and vegetation. There is great variability in the form of ''Hydnellum'' fruitbodies, which are greatly influenced by environmental conditions such as rainfall and humidity, drying winds, and temperature. They are too tough and woody to eat comfortably. Several species have become the focus of increasing conservation concern following widespread declines in abundance. ''Hydnellum'' species produce pigments that have been used to dye textiles. Several chemical compounds—some with unique biological activity—have been isolated and identified from the genus. One of the better-known species is the unusual pinkish-white ''Hydnellum peckii'', also known as "strawberries and cream" or as the "bleeding tooth fungus" due to the red d ...

Bankera
''Bankera'' is a genus of four species of tooth fungi in the family Bankeraceae. The genus was first circumscribed in 1951 by William Chambers Coker and Alma Holland Beers, but this publication was invalid according to the rules of botanical nomenclature. It was later published validly by Zdeněk Pouzar in 1955. The type species is '' B. fuligineoalba''. The genus is ectomycorrhizal with gymnosperms, usually with trees from the pine family. Fruitbodies of ''Bankera'' species are fleshy, usually with a centrally-placed stipe, and greyish-brown spines on the hymenial undersurface. The texture of the flesh ranges from soft to tough, but it lacks the zones associated with some other Bankeraceae genera. Dried flesh often has a fenugreek odor. Spores range in shape from more or less spherical to ellipsoid, and are hyaline (translucent), with thin walls. In deposit, they are white. ''Bankera'' has a monomitic hyphal system with brownish to hyaline, inflated generative hyphae. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stipe (mycology)
In mycology, a stipe () is the stem or stalk-like feature supporting the cap of a mushroom. Like all tissues of the mushroom other than the hymenium, the stipe is composed of sterile hyphal tissue. In many instances, however, the fertile hymenium extends down the stipe some distance. Fungi that have stipes are said to be stipitate. The evolutionary benefit of a stipe is generally considered to be in mediating spore dispersal. An elevated mushroom will more easily release its spores into wind currents or onto passing animals. Nevertheless, many mushrooms do not have stipes, including cup fungi, puffballs, earthstars, some polypores, jelly fungi, ergots, and smuts. It is often the case that features of the stipe are required to make a positive identification of a mushroom. Such distinguishing characters include: # the texture of the stipe (fibrous, brittle, chalky, leathery, firm, etc.) # whether it has remains of a partial veil (such as an annulus or cortina) or universal ve ...

Pileus (mycology)
The pileus is the technical name for the cap, or cap-like part, of a basidiocarp or ascocarp (fungal fruiting body) that supports a spore-bearing surface, the hymenium.Moore-Landecker, E: "Fundamentals of the Fungi", page 560. Prentice Hall, 1972. The hymenium (hymenophore) may consist of lamellae, tubes, or teeth, on the underside of the pileus. A pileus is characteristic of agarics, boletes, some polypores, tooth fungi, and some ascomycetes. Classification Pilei can be formed in various shapes, and the shapes can change over the course of the developmental cycle of a fungus. The most familiar pileus shape is hemispherical or ''convex.'' Convex pilei often continue to expand as they mature until they become flat. Many well-known species have a convex pileus, including the button mushroom, various ''Amanita'' species and boletes. Some, such as the parasol mushroom, have distinct bosses or umbos and are described as ''umbonate''. An umbo is a knobby protrusion at the center of th ...
