Royoporus
''Royoporus'' is a genus of fungi in the family Polyporaceae. It was circumscribed by mycologist Asit Baran De in 1996. The genus name honours Indian botanist Anjali Roy, (1930–2017), who worked at Visva-Bharati University in West Bengal. The genus is monotypic, being represented by the single species ''Royoporus spatulatus''.

Picipes Badius
''Picipes badius'' (formerly ''Royoporus badius''), commonly known as the black-footed polypore or black-leg, is a species of fungus in the family Polyporaceae. It causes a white rot of hardwoods and conifers. The species is found in temperate areas of Asia, Australia, Europe, and North America. It has a dark brown or reddish-brown cap that reaches a diameter of , and a stipe that is often completely black or brown at the top and black at the base. Taxonomy The species was first described in the scientific literature in 1801 by Christian Hendrik Persoon, who named it ''Boletus badius''. American mycologist Lewis David de Schweinitz transferred the species to ''Polyporus'' in 1832, and it was known by this name until 1997, when De transferred the species into the genus '' Royoporus'', which he had described the year before. Polyporaceae species that are closely phylogenetically related to ''Picipes badius'' include ''Polyporus dictyopus'', ''Polyporus melanopus'', and ''Polypor ...

Polyporaceae
The Polyporaceae are a family of poroid fungi belonging to the Basidiomycota. The flesh of their fruit bodies varies from soft (as in the case of the dryad's saddle illustrated) to very tough. Most members of this family have their hymenium (fertile layer) in vertical pores on the underside of the caps, but some of them have gills (e.g. ''Panus'') or gill-like structures (such as ''Daedaleopsis'', whose elongated pores form a corky labyrinth). Many species are brackets, but others have a definite stipe – for example, '' Polyporus badius''. Most of these fungi have white spore powder but members of the genus '' Abundisporus'' have colored spores and produce yellowish spore prints. Cystidia are absent. Taxonomy In his 1838 work ''Epicrisis Systematis Mycologici seu Synopsis Hymenomycetum'', Elias Magnus Fries introduced the "Polyporei". August Corda published the name validly the following year, retaining Fries's concept. American mycologist William Alphonso Murrill, ...

Anjali Roy
Anjali Roy (April 1930 – 22 January 2017) was an eminent Indian mycologist and academic. The fungus genus ''Royoporus'' is named in her honour. Early life Roy was born in April 1930 in Rajshahi, then in pre-Independence India and now in Bangladesh. She passed her matriculation examination from the girls' school there in 1945. She graduated with honors in botany from Presidency College, Calcutta, and her post-graduation from Ballygunge Science College in 1952. She obtained a D.Sc. from the Calcutta University under the guidance of S. N. Banerjee. Early research and academics Roy's initial post-doctoral research, on the ''Coriolellus'', was conducted in Canada where she was mentored by Mildred K. Nobles. Returning to India, she began work as a medical mycologist in the Calcutta School of Tropical Medicine. In 1974, she joined the University of Burdwan as a lecturer. Five years later, she moved to the Visva-Bharati University, where she remained until she retired in 199 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. 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 ...

Fungi
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'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...

Visva-Bharati University
Visva-Bharati () is a public central university and an Institution of National Importance located in Shantiniketan, West Bengal, India. It was founded by Rabindranath Tagore who called it ''Visva-Bharati'', which means the communion of the world with India. Until independence it was a college. Soon after independence, the institution was given the status of a central university in 1951 by an act of the Parliament. Overview ''The Hindu'' writes, "Santiniketan in many ways is still quite different compared to other universities in the country. Located at Bolpur in Birbhum district of West Bengal, the university still has the rural trappings that Tagore dreamt of. The classes are still held in the open under the shade of huge mango trees and students and tutors alike still travel by cycles to keep pollution at bay. The old buildings, even those that were made up of mud walls and thatched roofs, are still intact and find a place within the main campus. While some are preserved fo ...

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. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

Favolus Pseudobetulinus
''Favolus'', or honeycomb fungus, is a genus of fungi in the family Polyporaceae. The fruit bodies of ''Favolus'' species are fleshy with radially arranged pores on the underside of the cap that are angular and deeply pitted, somewhat resembling a honeycomb. Taxonomy The naturalist Palisot de Beauvois was the first to use the name ''Favolus'' in his 1805 work ''Flore d'Oware et de Benin, en Afrique''. His type species was ''Favolus hirtus'', a fungus first collected in Africa. Elias Fries used the name as a subgenus of '' Polyporus'' in 1821. Seven years later, Fries used the name ''Favolus'' for a different genus, with the tropical species ''F. brasiliensis'' as the type. Fries's concept of the genus was later accepted as it was published in one of the sanctioning works of mycology. ''Favolus hirtus'' is now called ''Trametes hirta'', and Beauvois' concept of ''Favolus'' is placed in synonymy with '' Trametes''. The generic name ''Favolus'' is derived from the Latin '' ...

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-decay fungus, 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 plant pathology, pathogens of trees and a few species that cause damage by rotting structural timber. Some of the Polyporales are commercially Fungiculture, 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 Basidiomycota () is one of two large divisions that, together with ...
