Oliveonia Termitophila
''Oliveonia'' is a genus of fungi in the order Auriculariales. Species form thin, effused, corticioid basidiocarps (fruit bodies) with microscopically prominent cystidia and aseptate basidia producing basidiospores that give rise to secondary spores. All species are believed to be saprotrophic, most growing on dead wood. The genus was originally published by American mycologist L.S. Olive in 1957 as ''Heteromyces'', but this is an illegitimate later homonym of the lichen A lichen ( , ) is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.Heteromyces'' Müll.Arg.

Marinus Anton Donk
Marinus Anton Donk (14 August 1908 – 2 September 1972) was a Dutch mycologist. He specialized in the taxonomy and nomenclature of mushrooms. Rolf Singer wrote in his obituary that he was "one of the most outstanding figures of contemporary mycology." Early life Donk was born in Situbondo, East Java in 1908, and completed secondary school in The Hague, Netherlands. He studied biology at the University of Utrecht, starting in 1927. As a graduate student in mycology he completed the work for his 1931 "Revisie van de Nederlandse Heterobasidiomyceteae" (Revision of the Dutch Heterobasidiomycetes). He completed his studies and attained a doctorate degree in 1933 with the second part of his work, ''Revisie van de Nederlandse Heterobasidiomyceteae II''. Afterwards he returned to Java, where he worked from 1934 to 1940 as a teacher, and, starting from 1941 as a curator in the herbarium of the Buitenzorg Botanical Garden. He was interned in a Japanese prison camp from 1942 to 1945. Du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cystidia
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heteromyces
''Heteromyces'' is a genus of lichenized fungi in the family Cladoniaceae. It is a monotypic genus, containing the single species ''Heteromyces rubescens''. Both the genus and species were described by Swiss lichenologist Johannes Müller Argoviensis in 1889. The name ''Heteromyces'' was also used for a genus circumscribed by Lindsay S. Olive in 1957; this usage is illegitimate because of the prior usage of this name by Müller. Olive's concept of ''Heteromyces'' was renamed to '' Oliveonia'' by Marinus Anton Donk Marinus Anton Donk (14 August 1908 – 2 September 1972) was a Dutch mycologist.

Lichen
A lichen ( , ) is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. Lichens have properties different from those of their component organisms. They come in many colors, sizes, and forms and are sometimes plant-like, but are not s. They may have tiny, leafless branches (); flat leaf-like structures ( |
Homonym (biology)
In biology, a homonym is a name for a taxon that is identical in spelling to another such name, that belongs to a different taxon. The rule in the International Code of Zoological Nomenclature is that the first such name to be published is the senior homonym and is to be used (it is " valid"); any others are junior homonyms and must be replaced with new names. It is, however, possible that if a senior homonym is archaic, and not in "prevailing usage," it may be declared a ''nomen oblitum'' and rendered unavailable, while the junior homonym is preserved as a ''nomen protectum''. :For example: :* Cuvier proposed the genus ''Echidna'' in 1797 for the spiny anteater. :*However, Forster had already published the name ''Echidna'' in 1777 for a genus of moray eels. :*Forster's use thus has priority, with Cuvier's being a junior homonym. :*Illiger published the replacement name ''Tachyglossus'' in 1811. Similarly, the International Code of Nomenclature for algae, fungi, and plants ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycologist
Mycology is the branch of biology concerned with the study of fungus, fungi, including their genetics, genetic and biochemistry, biochemical properties, their Taxonomy (biology), taxonomy and ethnomycology, their use to humans, including as a source for tinder, traditional medicine, Edible mushroom, food, and entheogens, as well as their dangers, such as poison, toxicity or fungal infection, infection. A biologist specializing in mycology is called a mycologist. Mycology branches into the field of phytopathology, the study of plant diseases, and the two disciplines remain closely related because the vast majority of plant pathogens are fungi. Overview Historically, mycology was a branch of botany because, although fungi are evolutionarily more closely related to animals than to plants, this was not recognized until a few decades ago. Pioneer mycologists included Elias Magnus Fries, Christian Hendrik Persoon, Anton de Bary, Elizabeth Eaton Morse, and Lewis David von Schweinitz ...

Saprotrophic
Saprotrophic nutrition or lysotrophic nutrition is a process of chemoheterotrophic extracellular digestion involved in the processing of decayed (dead or waste) organic matter. It occurs in saprotrophs, and is most often associated with fungi (for example ''Mucor'') and soil bacteria. Saprotrophic microscopic fungi are sometimes called saprobes; saprotrophic plants or bacterial flora are called saprophytes ( sapro- 'rotten material' + -phyte 'plant'), although it is now believed that all plants previously thought to be saprotrophic are in fact parasites of microscopic fungi or other plants. The process is most often facilitated through the active transport of such materials through endocytosis within the internal mycelium and its constituent hyphae. states the purpose of saprotrophs and their internal nutrition, as well as the main two types of fungi that are most often referred to, as well as describes, visually, the process of saprotrophic nutrition through a diagram of hyph ...

Basidiospores
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 in the ...

Basidia
A basidium () is a microscopic sporangium (a spore-producing structure) found on the hymenophore of fruiting bodies of basidiomycete fungi which are also called tertiary mycelium, developed from secondary mycelium. Tertiary mycelium is highly-coiled secondary myceliuma dikaryon. The presence of basidia is one of the main characteristic features of the Basidiomycota. A basidium usually bears four sexual spores called basidiospores; occasionally the number may be two or even eight. In a typical basidium, each basidiospore is borne at the tip of a narrow prong or horn called a sterigma (), and is forcibly discharged upon maturity. The word ''basidium'' literally means "little pedestal", from the way in which the basidium supports the spores. However, some biologists suggest that the structure more closely resembles a club. An immature basidium is known as a basidiole. Structure Most basidiomycota have single celled basidia (holobasidia), but in some groups basidia can be multice ...

Basidiocarps
In fungi, a basidiocarp, basidiome, or basidioma () is the sporocarp (fungi), sporocarp of a basidiomycota, basidiomycete, the Multicellular organism, multicellular structure on which the spore-producing hymenium is borne. Basidiocarps are characteristic of the hymenomycetes; Urediniomycetes, rusts and Ustilaginomycetes, smuts do not produce such structures. As with other sporocarps, epigeous (above-ground) basidiocarps that are visible to the naked eye (especially those with a more or less agaricoid morphology) are commonly referred to as mushrooms, while hypogeous (underground) basidiocarps are usually called false truffles. Structure All basidiocarps serve as the structure on which the hymenium is produced. Basidia are found on the surface of the hymenium, and the basidia ultimately produce spores. In its simplest form, a basidiocarp consists of an undifferentiated fruiting structure with a hymenium on the surface; such a structure is characteristic of many simple jelly fungi, ...
