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 new s ...

Cheilocystidia
A cystidium (plural 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 of cystidia 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 wit ...

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 ...

Henri Romagnesi
Henri Charles Louis Romagnesi (7 February 1912 – 18 January 1999) was a French mycologist who was notable for a thorough review and monograph of the agaric genus ''Entoloma'' (or ''Rhodophyllus'' as it was known in the early 20th century), as well as extensive work on the large genus ''Russula'', of which he described several new species. See also *List of mycologists This is a non-exhaustive list of mycologists, or scientists with a specialisation in mycology, with their author abbreviations.

Mushroom
A mushroom or toadstool is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground, on soil, or on its food source. ''Toadstool'' generally denotes one poisonous to humans. The standard for the name "mushroom" is the cultivated white button mushroom, ''Agaricus bisporus''; hence the word "mushroom" is most often applied to those fungi ( Basidiomycota, Agaricomycetes) that have a stem ( stipe), a cap ( pileus), and gills (lamellae, sing. lamella) on the underside of the cap. "Mushroom" also describes a variety of other gilled fungi, with or without stems, therefore the term is used to describe the fleshy fruiting bodies of some Ascomycota. These gills produce microscopic spores that help the fungus spread across the ground or its occupant surface. Forms deviating from the standard morphology usually have more specific names, such as "bolete", "puffball", "stinkhorn", and " morel", and gilled mushrooms themselves are often called "agarics" in refere ...

Hymenogastraceae
The Hymenogastraceae is a family of fungi in the order Agaricales with both agaric and false-truffle shaped fruitbodies. Formerly, prior to molecular analyses, the family was restricted to the false-truffle genera. The mushroom genus ''Psilocybe'' in the ''Hymenogastraceae'' is now restricted to the hallucinogenic species while nonhallucinogenic former species are largely in the genus ''Deconica'' classified in the Strophariaceae. One of the two known species of '' Wakefieldia'' has been found recently to belong to this family but formal transfer cannot be made until the phylogeny of the type species of the genus is resolved. '' Psathyloma'', added to the family in 2016, was circumscribed to contain two agarics found in New Zealand. Genera *'' Alnicola'' (12 species) *''Dendrogaster'' (1 species) *'' Galera'' (4 species) *''Galerina'' (307 species) *'' Galerula'' (3 species) *''Gymnopilus'' (209 species) *''Hebeloma'' (355 species) *'' Hymenogaster'' (79 species) *'' Naematoloma' ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ...

Hebeloma
''Hebeloma'' is a genus of fungi in the family Hymenogastraceae. Found worldwide, it contains the poison pie or fairy cakes ''(Hebeloma crustuliniforme)'' and the ghoul fungus ''( H. aminophilum)'', from Western Australia, which grows on rotting animal remains. Etymology The generic name is a compound Ancient Greek word ''hēbē'' (ἥβη), "youth" or "puberty" and the suffix -''loma'' (λόμα), a fringe (pertaining to the fungal veil). Thus, ''Hebeloma'' translates as "fringe of youth", in reference to how the fungal veil is only seen in immature specimens. Taxonomic placement The placement of the genus ''Hebeloma'' within the fungal taxonomic tree has varied over time. Historically it has been most often placed in the order Agaricales but was placed Cortinariales in the 8th edition of the Dictionary of the Fungi. The most recent inter-generic placement (Knudsen & Vesterholt, 2nd ed, 2012)) places it the family Hymenogastraceae The Hymenogastraceae is a family of fung ...

Fungi Described In 1965
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true fungi' ...
