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 mycology, mycologist.

Oliveonia
''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 hybrid colony (biology), colony of algae or cyanobacteria living symbiotically among hypha, filaments of multiple fungus species, along with yeasts and bacteria embedded in the cortex or "skin", in a mutualism (biology), m ... genus '' Heteromyces'' Müll.Arg.

Cladoniaceae
The Cladoniaceae are a family of lichen-forming fungi in the order Lecanorales, comprising about 560 species distributed amongst 18 genera. This family is one of the largest among lichen-forming fungi and is globally distributed, from Arctic tundra to tropical rainforests, favouring humid environments while being intolerant of arid conditions. Molecular phylogenetics has significantly advanced the understanding of their complex taxonomic history, revealing intricate evolutionary relationships and leading to a refined classification. Notable members include reindeer moss and cup lichens of the genus '' Cladonia'', which consist of about 500 species and forms a significant part of the diet for large mammals in taiga and tundra ecosystems. A distinctive feature of many Cladoniaceae species is their dimorphic thallus: a scaly or crust-like form and a (shrub-like) secondary form known as a podetium or . These lichens typically grow on soil, decaying wood, or tree trunks, with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Lichen
A lichen ( , ) is a hybrid colony (biology), colony of algae or cyanobacteria living symbiotically among hypha, filaments of multiple fungus species, along with yeasts and bacteria embedded in the cortex or "skin", in a mutualism (biology), mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. . Lichens are the lifeform that first brought the term symbiosis (as ''Symbiotismus'') into biological context. Lichens have since been recognized as important actors in nutrient cycling and producers which many higher trophic feeders feed on, such as reindeer, gastropods, nematodes, mites, and springtails. Lichens have properties different from those of their component organisms. They come in man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or 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 motility, 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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical syste ...

Johannes Müller Argoviensis
Johann Müller (9 May 1828 – 28 January 1896) was a Swiss botanist who was a specialist in lichens. He published under the name Johannes Müller Argoviensis to distinguish himself from other naturalists with similar names. Biography Müller was born into a farming family on 9 May 1828 in Teufenthal, Switzerland. He received his education at the Reinach, Aargau, Reinach gymnasium and then entered the Aargau industrial school, where he was passionate about botany and mathematics. Encouraged by Hans Schinz he built a herbarium of the flora of Aargau. In 1850 and 1851 he studied in Geneva and came into contact with prominent botanists Edmond Boissier and Alphonse Pyrame de Candolle (who offered him the vacant post of curator at his herbarium). In the spring of 1851 he collected in southern France with Jean Étienne Duby. The herbarium specimens from this trip were later sent to several herbaria in Europe. The following year, Müller travelled with Boissier to collect plants in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nomen Illegitimum
''Nomen illegitimum'' (Latin for illegitimate name) is a technical term used mainly in botany. It is usually abbreviated as ''nom. illeg.'' Although the International Code of Nomenclature for algae, fungi, and plants uses Latin terms as qualifiers for taxon names (e.g. ''nomen conservandum'' for "conserved name", and ''nomen superfluum'' for "superfluous name"), the definition of each term is in English rather than Latin. The Latin abbreviations are widely used by botanists and mycologists. Definition A ''nomen illegitimum'' is a validly published name (botany), validly published name, but one that contravenes some of the articles laid down by the International Botanical Congress.Melbourne Code (2012) The name could be illegitimate because: * (article 52) it was superfluous at its time of publication, i.e., the taxon (as represent ...

Principle Of Priority
Priority is a principle in Taxonomy (biology), biological taxonomy by which a valid scientific name is established based on the oldest available name. It is a decisive rule in Botanical nomenclature, botanical and zoological nomenclature to recognise the first Binomial nomenclature, binomial name (also called ''binominal name'' in zoology) given to an organism as the correct and acceptable name. The purpose is to select one scientific name as a stable one out of two or more alternate names that often exist for a single species. The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) defines it as: "A right to precedence established by the date of valid publication of a legitimate name or of an earlier homonym, or by the date of designation of a type." Basically, it is a scientific procedure to eliminate duplicate or multiple names for a species, for which Lucien Marcus Underwood called it "the principle of outlaw in nomenclature".

Marinus Anton Donk
Marinus Anton Donk (14 August 1908 – 2 September 1972) was a Dutch mycology, mycologist. He specialized in the Taxonomy (biology), 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 Bogor Botanical Gardens, Buitenzorg Botanical Garden.
