Gomphidius Glutinosus
''Gomphidius glutinosus'', commonly known as the slimy spike-cap, hideous gomphidius, or glutinous gomphidius is a gilled mushroom found in Europe & North America. Although it has gills, it is a member of the order Boletales, along with the boletes. The fruiting bodies sprout in pine, fir and spruce woodland in Europe in autumn. Initially, are completely covered with a slimy veil, breaking through to reveal a greyish or brownish-capped mushroom with decurrent greyish gills which sometimes resembles a child's top. Opinions differ on the suitability of this mushroom for the table, some guides hold it in high regard, while others view it with caution. Taxonomy ''Gomphidius glutinosus'' was initially described by German mycologist Jacob Christian Schäffer as ''Agaricus glutinosus'' in 1774, in his series on fungi of Bavaria and the Palatinate, ''Fungorum qui in Bavaria et Palatinatu circa Ratisbonam nascuntur icones.'' The father of mycology Elias Magnus Fries gave it its curre ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Kaniksu National Forest
The Kaniksu National Forest (pronounced , ) is a U.S. National Forest located in northeastern Washington, the Idaho Panhandle, and northwestern Montana. It is one of three forests that are aggregated into the Idaho Panhandle National Forests, along with the Coeur d'Alene National Forest and St. Joe National Forest. Kaniksu National Forest has a total area of . About 55.7% is in Idaho, 27.9% in Montana, and 16.4% in Washington. The name ''Kaniksu'' is from a Kalispel Indian word which means "black robe." It was used to refer to the Jesuit missionaries who brought their faith to North Idaho and Eastern Washington. History Kaniksu National Forest was established on July 1, 1908, from a portion of Priest River National Forest. On September 30, 1933, a portion of Pend Oreille National Forest was added, and on July 1, 1954, part of Cabinet National Forest was added. Kaniksu was administratively combined with Coeur d'Alene and St. Joe National Forests on July 1, 1973. The fore ...

Gomphidius Smithii
''Gomphidius'' is a genus of mushrooms, commonly known as spike-caps, that are members of the Boletales (suborder Suillineae), or pored fungi. They appear to have gill-like structures which resemble those of agarics, however the similarity is superficial only. The best-known member is the slimy spike-cap (''Gomphidius glutinosus''). The genus has a widespread distribution, especially in north temperate areas, and contains 10 species. Taxonomy Elias Magnus Fries initially described the genus as ''Agaricus'' subgenus ''Gomphus'' in 1821, before renaming it ''Gomphidius'' in 1825. The genus gives its name to the family Gomphidiaceae. Despite being agaricoid (bearing gills) the genus (and family) belong to the Boletales (suborder Suillineae). The related genus ''Chroogomphus'' (whose species were once classified in ''Gomphidius''), is distinguished by the lack of a partial veil. The genus name is derived from the Greek 'γομφος' ''gomphos'' meaning 'plug' or 'large wedge-shape ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Hygrophorus Hypothejus
''Hygrophorus hypothejus'', commonly known as the olive-brown waxy cap, or herald of the winter, is an edible species of fungus in the genus ''Hygrophorus'' native to Europe. It appears in late autumn in coniferous forests, often with the first frosts. Taxonomy Elias Magnus Fries described this species in 1821 as ''Agaricus hypothejus'', before placing it in the genus ''Hygrophorus'' in 1838. Its species name is derived from the Ancient Greek words ''hypo'' and ''theios'' "sulphur yellow underneath". It has the common name of herald of the winter as it appears in autumn with the onset of the first overnight frosts. Alternate names are late fall waxy cap in the United States, and yellow-gilled waxcap. Description The cap measures across, is yellowish to olive brown with a dark center and slimy surface, and has a rolled margin when young, flattening and becoming more funnel-shaped as it ages. The yellow gills are decurrent, and the flesh is pale yellow, turning orange-red when br ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Suillus Luteus
''Suillus luteus'' is a bolete fungus, and the type species of the genus ''Suillus''. Commonly referred to as slippery jack or sticky bun in English-speaking countries, its names refer to the brown pileus (mycology), cap, which is characteristically slimy in wet conditions. The fungus, initially described as ''Boletus luteus'' ("yellow mushroom") by Carl Linnaeus in 1753, is now classified in a different fungus family (biology), family as well as genus. The fruit body cap often has a distinctive conical shape before flattening with age, reaching up to in diameter. Like other boletes, it has Fungal tubes, tubes extending downward from the underside of the cap, rather than lamella (mycology), gills; spores escape at maturity through the tube openings, or pores. The pore surface is yellow, and covered by a membranous partial veil when young. The pale Stipe (mycology), stipe, or stem, measures up to 10 cm (4 in) tall and thick and bears small dots near the top. Unlike mo ...

Spore Print
300px, Making a spore print of the mushroom ''Volvariella volvacea'' shown in composite: (photo lower half) mushroom cap laid on white and dark paper; (photo upper half) cap removed after 24 hours showing warm orange ("tussock") color spore print. A 3.5-centimeter glass slide placed in middle allows for examination of spore characteristics under a microscope. The spore print is the powdery deposit obtained by allowing spores of a fungal fruit body to fall onto a surface underneath. It is an important diagnostic character in most handbooks for identifying mushrooms. It shows the colour of the mushroom spores if viewed en masse. Method A spore print is made by placing the spore-producing surface flat on a sheet of dark and white paper or on a sheet of clear, stiff plastic, which facilitates moving the spore print to a darker or lighter surface for improved contrast; for example, it is easier to determine whether the spore print is pure white or, rather, very slightly pigmented. ...

Basidiospore
A basidiospore is a reproductive spore produced by basidiomycete fungi, a grouping that includes mushrooms, shelf fungi, rusts, and smuts. Basidiospores typically each contain one haploid Ploidy () is the number of complete sets of chromosomes in a cell (biology), cell, and hence the number of possible alleles for Autosome, autosomal and Pseudoautosomal region, pseudoautosomal genes. Here ''sets of chromosomes'' refers to the num ... nucleus (biology), nucleus that is the product of meiosis, and they are produced by specialized fungal cells called basidium, basidia. Typically, four basidiospores develop on appendages from each basidium, of which two are of one Strain (biology), strain and the other two of its opposite strain. In gills under a cap of one common species, there exist millions of basidia. Some gilled mushrooms in the order Agaricales have the ability to release billions of spores. The puffball fungus ''Calvatia gigantea'' has been calculated to produce about ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cystidia
A cystidium (: cystidia) is a relatively large cell found on the sporocarp of a basidiomycete (for example, on the surface of a mushroom gill), often between clusters of basidia. Since cystidia have highly varied and distinct shapes that are often unique to a particular species or genus, they are a useful micromorphological characteristic in the identification of basidiomycetes. In general, the adaptive significance of cystidia is not well understood. Classification By position Cystidia may occur on the edge of a lamella (or analogous hymenophoral structure) (cheilocystidia), on the face of a lamella (pleurocystidia), on the surface of the cap (dermatocystidia or pileocystidia), on the margin of the cap (circumcystidia) or on the stipe (caulocystidia). Especially the pleurocystidia and cheilocystidia are important for identification within many genera. Sometimes the cheilocystidia give the gill edge a distinct colour which is visible to the naked eye or with a hand lens. ...

Melzer's Reagent
Melzer's reagent (also known as Melzer's iodine reagent, Melzer's solution or informally as Melzer's) is a chemical reagent used by mycologists to assist with the identification of fungi, and by phytopathologists for fungi that are plant pathogens. Composition Melzer's reagent is an aqueous solution of chloral hydrate, potassium iodide, and iodine. Depending on the formulation, it consists of approximately 2.50-3.75% potassium iodide and 0.75–1.25% iodine, with the remainder of the solution being 50% water and 50% chloral hydrate. Melzer's is toxic to humans if ingested due to the presence of iodine and chloral hydrate. Due to the legal status of chloral hydrate, Melzer's reagent is difficult to obtain in the United States. In response to difficulties obtaining chloral hydrate, scientists at Rutgers formulated Visikol (compatible with Lugol's iodine) as a replacement. In 2019, research showed that Visikol behaves differently to Melzer’s reagent in several key situations, notin ...

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 (ring) or cortina) or ...

Annulus (mycology)
An annulus is the ring-like or collar-like structure sometimes found on the Stipe (mycology), stipe of some species of mushrooms. The annulus represents the remnants of the partial veil, after it has ruptured to expose the gill (mushroom), gills or other spore-producing surface. It can also be called a ring which is what the Latin word annulus directly translates as. The modern usage of the Latin word originates from the early days of botany and mycology when species Species description, descriptions were only written in Latin. Outside of the formal setting of scientific publications which still have a Latin requirement, it will often just be referred to as a ring or stem ring in field guides and on identification websites. Ring descriptions The way in which the structure and appearance of rings is described can vary with author and the description may only note the existence of a ring without providing specific information in cases where the ring lacks any notable features that ...
