Elmerina
} ''Elmerina'' is a genus of fungi in the order Auriculariales. Basidiocarps (fruit bodies) are formed on dead wood and are either bracket-like with a poroid hymenium or densely clavarioid. Species are known from East Asia and Australia. Taxonomy History ''Elmerina '' was described by Italian mycologist Giacomo Bresadola to accommodate a distinctive polypore originally collected in the Philippines during the ''Challenger'' expedition. Bresadola named the genus in honour of Adolph Daniel Edward Elmer, an American botanist and plant collector. English mycologist Derek Reid later discovered that the basidia of the polypore were septate, thus placing the genus among the heterobasidiomycetes, and referred all species of poroid Auriculariales to ''Elmerina''. Current status Molecular research, based on cladistic analysis of DNA sequences, has shown that ''Elmerina'' is a distinct genus, but only includes a minority of poroid Auriculariales, others being placed in the closely rela ...

Protomerulius
''Protomerulius'' is a genus of fungi in the order Auriculariales. Basidiocarps (fruit bodies) are formed on dead wood and have an effused, smooth, spiny, or poroid hymenium. The genus is cosmopolitan. Taxonomy The genus was originally described from Brazil to accommodate a fungus that resembled a polypore but microscopically had septate basidia. The genus name was subsequently extended to include other fungi with a similar combination of features. Molecular research, based on cladistic analysis of DNA sequences, has shown, however, that the type species of ''Protomerulius'', ''P. brasiliensis'' (a synonym of ''P. substuppeus'') is not closely related to most other poroid species with septate basidia, some of which are now placed in the genera '' Aporpium'', '' Elmerina'', and ''Protodaedalea ''Protodaedalea'' is a genus of fungi in the family Auriculariaceae.

Auriculariales
The Auriculariales are an order of fungi in the class Agaricomycetes. Species within the order were formerly referred to the "heterobasidiomycetes" or "jelly fungi", since many have gelatinous basidiocarps (fruit bodies) that produce spores on septate basidia. Around 200 species are known worldwide, placed in six or more families, though the status of these families is currently uncertain. All species in the Auriculariales are believed to be saprotrophic, most growing on dead wood. Fruit bodies of several ''Auricularia'' species are cultivated for food on a commercial scale, especially in China. Taxonomy History The order was established in 1889 by German mycologist Joseph Schröter to accommodate species of fungi having "auricularioid" basidia (more or less cylindrical basidia with lateral septa), including many of the rusts and smuts. In 1922, British mycologist Carleton Rea recognized the order as containing the families Auriculariaceae and Ecchynaceae, as well as the rus ...

Adolph Daniel Edward Elmer
Adolph Daniel Edward Elmer (June 14, 1870 – 1942) was an American botanist and plant collector.. He was mostly active in the Philippines, his collections being described as new species by both himself and other botanists. The Japanese sent him into Santo Tomas Internment Camp during the Philippines campaign and he died there. Life and achievements Elmer was born on June 14, 1870 in Van Dyne, Wisconsin, United States,. to Jacob Van Dyne and Alvina Elmer. He was educated at Washington State College in 1899,.. married Emma Osterman in 1902 and earned an A.M. from Stanford University in 1903 (or 1904). Between 1896 and the year of the earning of his A.M., he collected numerous plants in Western United States (especially California) then began describing new plant species, his name appearing in earlier numbers of (e.g. ''Festuca idahoensis'' in 1903). In 1904, he went to the Philippines (an unincorporated territory of the United States at that time), where he consequently made ...

DNA Sequences
A nucleic acid sequence is a succession of bases signified by a series of a set of five different letters that indicate the order of nucleotides forming alleles within a DNA (using GACT) or RNA (GACU) molecule. By convention, sequences are usually presented from the 5' end to the 3' end. For DNA, the sense strand is used. Because nucleic acids are normally linear (unbranched) polymers, specifying the sequence is equivalent to defining the covalent structure of the entire molecule. For this reason, the nucleic acid sequence is also termed the primary structure. The sequence has capacity to represent information. Biological deoxyribonucleic acid represents the information which directs the functions of an organism. Nucleic acids also have a secondary structure and tertiary structure. Primary structure is sometimes mistakenly referred to as ''primary sequence''. Conversely, there is no parallel concept of secondary or tertiary sequence. Nucleotides Nucleic acids consis ...

Cladistic
Cladistics (; ) is an approach to biological classification in which organisms are categorized in groups (" clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics ( synapomorphies'')'' that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically, outside of cladistics, e.g. as a 'grade', which are fruitless to precisely delineate, especially when including extinct species. R ...

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Heterobasidiomycetes
Heterobasidiomycetes, including jelly fungi, smuts and rusts, are basidiomycetes with Septum, septate Basidium, basidia. This contrasts them to homobasidiomycetes (alternatively called holobasidiomycetes), including most mushrooms and other Agaricomycetes, which have aseptate basidia. The division of all basidiomycetes between these two groups has been influential in fungal Taxonomy (biology), taxonomy, and is still used informally, but it is no longer the basis of formal classification. In modern taxonomy homobasidiomycetes roughly correspond to the monophyletic class Agaricomycetes, whereas heterobasidiomycetes are paraphyletic and as such correspond to various taxa from different Taxonomic rank#Ranks in botany, taxonomic ranks, including the Basidiomycota other than Agaricomycetes and a few Basal (phylogenetics), basal groups within Agaricomycetes. Distinction between homo- and heterobasidiomycetes In addition to having septate basidia, heterobasidiomycetes also frequently pos ...

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 ...

Giacomo Bresadola
Giacomo Bresadola ( Mezzana, Trento; often given as Giacopo) 14 February 1847 – Trento 9 June 1929) was an eminent Italian mycologist. Fungi he named include the deadly '' Lepiota helveola'' and ''Inocybe patouillardii'', though the latter is now known as '' Inosperma erubescens'' as this latter description predated Bresadola's by a year. He was a founding member of the ''Société mycologique de France'' (Mycology Society of France). Life Bresadola was born in 1847 into a farming family in Trent, then an Austrian possession. From a very early age, he showed an interest in botany. After attending elementary school at Mezzana, he was sent by his father to Cloz in the Val di Non at the age of nine to continue his studies with his uncle who was a priest. His uncle, however, considered him too rambunctious and quickly sent him home again. In 1857, his father moved to Montichiari in Brescia to become a bronze merchant. At twelve years of age, he left to study at the technical i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
