Mycoleptodonoides
''Mycoleptodonoides'' is a genus of hydnoid fungus, tooth fungi in the family Meruliaceae. The genus was circumscription (taxonomy), circumscribed by M.I. Nikolajeva in 1952 with ''Mycoleptodonoides vassiljevae, M. vassiljevae'', described from Ussuri, Russia, as the type species. This fungus, known only from the type locality (biology), type locality and northern China, is little known. The more widely distributed ''Mycoleptodonoides aitchisonii, M. aitchisonii'' is found in habitats ranging from subtropical to boreal ecosystem, boreal. The generic name combines the name ''Mycoleptodon'' and the Ancient Greek, Greek root ''-oides'', meaning "resembling".

Polyporales Genera
The Polyporales are an order of about 1800 species of fungi in the division Basidiomycota. The order includes some (but not all) polypores as well as many corticioid fungi and a few agarics (mainly in the genus ''Lentinus''). Many species within the order are saprotrophic, most of them wood-rotters. Some genera, such as ''Ganoderma'' and ''Fomes'', contain species that attack living tissues and then continue to degrade the wood of their dead hosts. Those of economic importance include several important pathogens of trees and a few species that cause damage by rotting structural timber. Some of the Polyporales are commercially cultivated and marketed for use as food items or in traditional Chinese medicine. Taxonomy History The order was originally proposed in 1926 by Swiss mycologist Ernst Albert Gäumann to accommodate species within the phylum Basidiomycota producing basidiocarps (fruit bodies) showing a gymnocapous mode of development (forming the spore-bearing surface exte ...

Meruliaceae
The Meruliaceae are a family of fungi in the order Polyporales. According to a 2008 estimate, the family contains 47 genera and 420 species. , Index Fungorum accepts 645 species in the family. Taxonomy The family was formally circumscribed by English mycologist Carleton Rea in 1922, with ''Merulius'' as the type genus. He also included the genera '' Phlebia'', ''Coniophora'' (now placed in the Coniophoraceae), and ''Coniophorella'' (now considered a synonym of ''Coniophora''). His description of the Meruliaceae was as follows: "Hymenium spread over veins, anastomosing pores, or quite smooth; ''edge of veins or pores fertile.''" Several genera formerly classified in the Meruliaceae were moved to the family Steccherinaceae based on molecular evidence. Description Meruliaceae species are crust-like or polyporoid, and often have a waxy appearance when dry. Their hyphal systems are monomitic (containing only tightly arranged generative hyphae), and these hyphae have clamp connect ...

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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycoleptodon
''Steccherinum'' is a widely distributed genus of toothed crust fungi in the family Steccherinaceae. Taxonomy ''Steccherinum'' was circumscribed by Samuel Frederick Gray in his 1821 work ''A Natural Arrangement of British Plants''. Description ''Steccherinum'' fungi have a range of fruit body morphologies, including resupinate (crust-like), effused-reflexed (crust-like with the edges extending outwards to form caps), or pileate with either a stipe or only a stipe-like base. Species A 2008 estimate placed 33 species in ''Steccherinum''. , Index Fungorum accepts 50 species: *'' S. agaricoides'' (Sw.)

Amyloid (mycology)
In mycology a tissue or feature is said to be amyloid if it has a positive amyloid reaction when subjected to a crude chemical test using iodine as an ingredient of either Melzer's reagent or Lugol's solution, producing a blue to blue-black staining. The term "amyloid" is derived from the Latin ''amyloideus'' ("starch-like"). It refers to the fact that starch gives a similar reaction, also called an amyloid reaction. The test can be on microscopic features, such as spore walls or hyphal walls, or the apical apparatus or entire ascus wall of an ascus, or be a macroscopic reaction on tissue where a drop of the reagent is applied. Negative reactions, called inamyloid or nonamyloid, are for structures that remain pale yellow-brown or clear. A reaction producing a deep reddish to reddish-brown staining is either termed a dextrinoid reaction (pseudoamyloid is a synonym) or a hemiamyloid reaction. Melzer's reagent reactions Hemiamyloidity Hemiamyloidity in mycology refers to a specia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 nucleus that is the product of meiosis, and they are produced by specialized fungal cells called basidia. Typically, four basidiospores develop on appendages from each basidium, of which two are of one 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 five trillion basidiospores. Most basidiospores are forcibly discharged, and are thus considered ballistospores. These spores serve as the main air dispersal units for the fungi. The spores are released during periods of high humidity and generally have a night-time or pre-dawn peak concentration ...
