Germ Pore
A germ pore is a small pore in the outer wall of a fungal spore through which the germ tube exits upon germination. It can be wikt:apical, apical or eccentric in its location, and, on light microscopy, may be visualized as a lighter coloured area on the cell wall. Apical germ pore is mushroom spore which has a pore at one end. Some spores have a hole in the cell wall where the first strand of germinating mycelium emerges. If the cell wall is divided from one end to the other, this is called a germ slit. Commonly the germ pore is at one end of the mushroom spore and is called an apical pore. Mushroom genera with apical germ pores include ''Agrocybe'', ''Panaeolus'', ''Psilocybe'', and ''Pholiota''.

Panaeolus Germ Pores
''Panaeolus'' is a genus of small, black-spored, Saprotrophic nutrition, saprotrophic agarics. The word ''Panaeolus'' is Ancient Greek, Greek for "all variegated", alluding to the spotted gills of the mushrooms produced. Characteristics These fungi are mostly Coprophilous fungi, dung and grassland species, some of which are quite common in Europe and North America. The Lamella (mycology), gills of ''Panaeolus'' do not wikt:deliquesce, deliquesce (liquefy) as do the members of the related genera ''Coprinellus'' and ''Coprinopsis''. Members of ''Panaeolus'' can also be mistaken for ''Psathyrella'', however the latter genus is usually found lignicolous, growing on wood or lignin-enriched soils and has brittle stipe (mycology), stipes. The gills of these mushrooms are black or grey and have a spotty, speckled or cloudy appearance, caused by the way that the dark spores ripen together in tiny patches on the gill surface; different patches darken at different times. The spores are sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spore
In biology, a spore is a unit of sexual reproduction, sexual (in fungi) or asexual reproduction that may be adapted for biological dispersal, dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the Biological life cycle, life cycles of many plants, algae, fungus, fungi and protozoa. They were thought to have appeared as early as the mid-late Ordovician period as an adaptation of early land plants. 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. In some rare cases, a diploid spore is also p ...

Light Microscopy
Microscopy is the technical field of using microscopes to view subjects too small to be seen with the naked eye (objects that are not within the resolution range of the normal eye). There are three well-known branches of microscopy: optical, electron, and scanning probe microscopy, along with the emerging field of X-ray microscopy. Optical microscopy and electron microscopy involve the diffraction, reflection, or refraction of electromagnetic radiation/electron beams interacting with the specimen, and the collection of the scattered radiation or another signal in order to create an image. This process may be carried out by wide-field irradiation of the sample (for example standard light microscopy and transmission electron microscopy) or by scanning a fine beam over the sample (for example confocal laser scanning microscopy and scanning electron microscopy). Scanning probe microscopy involves the interaction of a scanning probe with the surface of the object of interest. The de ...

Mycelium
Mycelium (: mycelia) is a root-like structure of a fungus consisting of a mass of branching, thread-like hyphae. Its normal form is that of branched, slender, entangled, anastomosing, hyaline threads. Fungal colonies composed of mycelium are found in and on soil and many other substrates. A typical single spore germinates into a monokaryotic mycelium, which cannot reproduce sexually; when two compatible monokaryotic mycelia join and form a dikaryotic mycelium, that mycelium may form fruiting bodies such as mushrooms. A mycelium may be minute, forming a colony that is too small to see, or may grow to span thousands of acres as in '' Armillaria''. Through the mycelium, a fungus absorbs nutrients from its environment. It does this in a two-stage process. First, the hyphae secrete enzymes onto or into the food source, which break down biological polymers into smaller units such as monomers. These monomers are then absorbed into the mycelium by facilitated diffusion and ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germ Slit
A germ pore is a small pore in the outer wall of a fungal spore through which the germ tube exits upon germination. It can be apical or eccentric in its location, and, on light microscopy, may be visualized as a lighter coloured area on the cell wall. Apical germ pore is mushroom spore which has a pore at one end. Some spores have a hole in the cell wall where the first strand of germinating mycelium emerges. If the cell wall is divided from one end to the other, this is called a germ slit. Commonly the germ pore is at one end of the mushroom spore and is called an apical pore. Mushroom genera with apical germ pores include '' Agrocybe'', ''Panaeolus'', ''Psilocybe'', and ''Pholiota''.

Agrocybe
''Agrocybe'' is a genus of mushrooms in the family Strophariaceae (previously placed in the Bolbitiaceae). The genus has a widespread distribution, and contains about 100 species. Distribution In Europe, toxic forms are not normally found, but ''Agrocybe molesta'' could be confused with poisonous white ''Agaricus'' species or with poisonous ''Amanita'' species. Uses Mushroom cultivation began with the Romans and Greeks, who grew the small ''Agrocybe aegerita''. The Romans believed that fungi fruited when lightning struck. ''A. aegerita'' is commonly known as the poplar mushroom, chestnut mushroom or velvet pioppino (Chinese: 茶樹菇). It is a white rot fungus. It is cultivated and sold in Japan, Korea, Australia and China. It is an important valuable source of bioactive secondary metabolites such as indole derivatives with free radical scavenging activity, cylindan with anticancer activity, and also agrocybenine with antifungal activity. '' Agrocybe farinacea'' of Japan, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Psilocybe
''Psilocybe'' ( ) is a genus of gilled mushrooms, growing worldwide, in the family Hymenogastraceae. Many species contain the Psychedelic drug, psychedelic compounds psilocybin and psilocin. Taxonomy Taxonomic history A 2002 study of the molecular phylogeny of the agarics indicated the genus ''Psilocybe'' as then defined was polyphyletic, falling into two distinct clades that are not directly related to each other. The blue-staining Hallucinogenic mushroom, hallucinogenic species constituted one clade and the non-bluing species the other. The previous Type (biology), type species of the genus, ''Psilocybe '' (now ''Deconica montana''), was in the non-bluing clade, but in 2010, the type species was changed to ''Psilocybe semilanceata, P. semilanceata'', a member of the bluing clade. A 2006 molecular phylogenetic study of the Agaricales by Matheny and colleagues, further demonstrated the separation of the bluing and non-bluing clades of ''Psilocybe'' in a larger, strongl ...

Pholiota
''Pholiota'' is a genus of small to medium-sized, fleshy mushrooms in the family Strophariaceae. They are saprobes that typically live on wood. The genus has a widespread distribution, especially in temperate regions, and contains about 150 species. ''Pholiota'' is derived from the Greek word ''pholis'', meaning "scale". Taxonomic details The genus ''Pholiota'' includes mushrooms, with scaly, glutinous to dry cap surfaces, and that frequently grow on wood or at the bases of trees or on decaying tree roots, and spores that are brown, light brown, or yellowish brown in deposit. These spores are smooth with a germ pore, although the germ pore can be quite narrow in species. Usually the species have pleurocystidia that include a type called chrysocystidia. There have been several varying concepts of the genus, ranging from a pre-molecular era very broad concept that nowadays would include the genera '' Phaeolepiota'', '' Phaeonematoloma'', '' Flammula'', '' Meottomyces'', some ...
