Polyporus Gayanus
''Polyporus gayanus'' is a species of fungus in the genus '' Polyporus''. It was first documented in 1846 by French mycologist Joseph-Henri Léveillé Joseph-Henri Léveillé (28 May 1796 – 3 February 1870) was a French physician and mycologist who was a native of Crux-la-Ville, in the department of Nièvre.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungus
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 f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyporus
''Polyporus'' is a genus of poroid fungi in the family Polyporaceae. Taxonomy Italian botanist Pier Antonio Micheli introduced the genus in 1729 to include 14 species featuring fruit bodies with centrally-placed stipes, and pores on the underside of the cap. The generic name combines the Ancient Greek words ("many") and ("pore"). Elias Fries divided ''Polyporus'' into three subgenera in his 1855 work ''Novae Symbol Mycologici'': ''Eupolyporus'', ''Fomes'', and ''Poria''. In a 1995 monograph, Maria Núñez and Leif Ryvarden grouped 32 ''Polyporus'' species into 6 morphologically-based infrageneric groups: ''Admirabilis'', ''Dendropolyporus'', ''Favolus'', ''Polyporellus'', ''Melanopus'', and ''Polyporus'' ''sensu stricto''. The identity of the type species of ''Polyporus'' has long been a matter of contention among mycologists. Some have preferred '' P. brumalis'', some '' P. squamosus'', while others have preferred '' P. tuberaster''. Several molecular phylo ...

Joseph-Henri Léveillé
Joseph-Henri Léveillé (28 May 1796 – 3 February 1870) was a French physician and mycologist who was a native of Crux-la-Ville, in the department of Nièvre. Léveillé studied medicine and mycology at the University of Paris, and in 1824 received his medical doctorate. In his 1837 paper ''Sur le hymenium des champignons'', he provided an early, comprehensive description of the basidium and cystidium of basidiomycete fungi, and was able to establish the role that the basidium played in spore production. Also, he made important findings in regard to the true nature of individual members of the so-called genus "Sclerotium". Selected writings * ''Sur le hymenium des champignons'' (1837) * ''Memoire sur le genre Sclerotium'' (1843) * ''Considérations mycologiques, suivies d'une nouvelle classification des champignons'' (1846) * ''Iconographie des Champignons de Paulet'' (1855) Honours He is honoured in the naming of '' Leveillella'' in 1915, which is a genus of fungi in the As ...
