Fungal Pores
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''.

Panaeolus Germ Pores
''Panaeolus'' is a genus of small, black-spored, saprotrophic agarics. The word ''Panaeolus'' is Greek for "all variegated", alluding to the spotted gills of the mushrooms produced. Characteristics These fungi are mostly dung and grassland species, some of which are quite common in Europe and North America. The gills of ''Panaeolus'' do not deliquesce 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 growing on wood or lignin-enriched soils and has brittle 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 smooth. The closely related genus '' Panaeolina'' shares the spotted gills but they are dark brown (not black) and the spores are ...

Spore
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apical
Apical means "pertaining to an apex". It may refer to: *Apical ancestor, refers to the last common ancestor of an entire group, such as a species (biology) or a clan (anthropology) *Apical (anatomy), an anatomical term of location for features located opposite the base of an organism or structure * Apical (chemistry), a position in certain molecular geometries in chemistry * Apical (dentistry), direction towards the root tip of a tooth *Apical consonant, a consonant produced with the tip of the tongue *Apical dendrite, a type of dendrite found on pyramidal neurons * Apical dominance, the phenomenon whereby the main, central stem of a plant is dominant over other side stems *Apical membrane The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates and protects the interior of all cells from the outside environment (th ..., in cell biology the surface of a plasma mem ...

Light Microscopy
Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot 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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycelium
Mycelium (plural mycelia) is a root-like structure of a fungus consisting of a mass of branching, thread-like hyphae. 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 active transport. Mycelia are vital in terrestrial and aquatic ecosystems for their role ...

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 Mushroom cultivation began with the Romans and Greeks, who grew the small ''Agrocybe aegerita''. The Romans believed that fungi fruited when lightning struck. In Europe, toxic forms are not normally found, but ''Agrocybe molesta'' could be confused with poisonous white ''Agaricus'' species or with poisonous ''Amanita'' species. The edible southern species ''Agrocybe aegerita'' is commonly known as the Poplar mushroom, Chestnut mushroom or Velvet pioppino (Chinese: 茶樹菇). It is a white rot fungus and is a medium-sized agaric with a convex, almost flat, cap 3 to 10 cm in diameter. Underneath, it has numerous whitish radial plates adherent to the foot, later turning to a brownish-gray color, and light elliptic spores of 8-11 by 5-7 micrometres. The white fiber foot is generally cu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Psilocybe
''Psilocybe'' ( ) is a genus of gilled mushrooms, growing worldwide, in the family Hymenogastraceae. Most or nearly all species contain the psychedelic compounds psilocybin and psilocin. Taxonomy Taxonomic history A 2002 study of the molecular phylogeny of the agarics indicated that 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 species constituted one clade and the non-bluing species the other. The previous type species of the genus, ''Psilocybe '' (now Deconica montana), was in the non-bluing clade, but in 2010 the type species was changed to '' 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, strongly supported phylogenetic tree of the Agaricales. ''Psilocybe'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
