Naohidea
''Naohidea sebacea'' is a species of fungus in the order Naohideales. The order is currently monotypic, having only one family, one genus, and one species. Basidiocarps (fruit bodies) of ''Naohidea sebacea'' form small, gelatinous pustules on wood-inhabiting species of Botryosphaeriaceae. Microscopically, they produce long, slender, auricularioid basidia (with lateral septa) and amygdaliform (almond-shaped) basidiospores. Taxonomy The species was first described in 1871 as ''Dacrymyces sebaceus'' by the Rev. Miles Joseph Berkeley and Christopher Edmund Broome, based on specimens collected by Broome in Somerset, England. Fruit bodies have a superficial resemblance to ''Dacrymyces'' species and the name was largely forgotten until New Zealand mycologist Ross McNabb re-examined Broome's specimens in 1965, discovered they represented a fungus with auricularioid basidia, and referred the species to the genus '' Platygloea'' sensu lato. German mycologist Franz Oberwinkler investigated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platygloea
''Platygloea'' is a genus of fungi belonging to the class Pucciniomycetes. Basidiocarps (fruit bodies) of the type species are disc-shaped, gelatinous, and occur on dead wood, probably as a saprotroph. Microscopically, all species of ''Platygloea'' sensu lato have auricularioid (laterally septate) basidia. Currently the genus (together with its possible synonym ''Achroomyces'' Bonord.) contains a heterogeneous mix of auricularioid fungi not yet accommodated in other genera. Taxonomy History ''Platygloea'' was proposed in 1887 by German mycologist Joseph Schröter for fungi with auricularioid (tubular and laterally septate) basidia and effused, waxy or gelatinous fruit bodies. Three species were included: ''Platygloea nigricans'' (now '' Platygloea disciformis''); ''P. fimicola'' (now '' Cystobasidium fimetarium''); and ''P. effusa'' (now '' Colacogloea effusa''). Subsequent authors referred additional species to ''Platygloea''. In a 1956 paper, American mycologist Robert Bandoni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miles Joseph Berkeley
Miles Joseph Berkeley (1 April 1803 – 30 July 1889) was an English cryptogamist and clergyman, and one of the founders of the science of plant pathology. Life Berkeley was born at Biggin Hall, Benefield, Northamptonshire, and educated at Rugby School and Christ's College, Cambridge. Taking holy orders, he became incumbent of Apethorpe in 1837, and vicar of Sibbertoft, near Market Harborough, in 1868. He acquired an enthusiastic love of cryptogamic botany (lichens) in his early years, and soon was recognized as the leading British authority on fungi and plant pathology. Christ's College made him an honorary fellow in 1883. He was well known as a systematist in mycology with some 6000 species of fungi being credited to him, but his ''Introduction to Cryptogamic Botany'', published in 1857, and his papers on Vegetable Pathology in the ''Gardener's Chronicle'' in 1854 and onwards, show that he had a broad grasp of the whole domain of physiology and morphology as understood ...

Ross McNabb
Robert Francis Ross McNabb (11 December 1934 – 14 December 1972) was a New Zealand mycologist. He was born in Kawakawa, and attended local schools in his youth, including Whangarei Boys' High School and Southland Boys' High School. He received a BSc degree from the University of Otago in 1956, and two years later an MSc for his work on mycorrhizae morphology in native New Zealand plants. In 1961, having been awarded a National Research Fellowship the year before, McNabb left New Zealand for the UK to study with Cecil Terence Ingold at Birkbeck College. McNabb earned a PhD in 1963; his thesis was titled "Taxonomic studies in the Dacrymycetaceae". He was jointly awarded the Hamilton Memorial Prize in 1966 from The Royal Society of New Zealand, the same year he was appointed to the editorial board of the ''New Zealand Journal of Botany''. Most of McNabb's later publications, largely published in this journal, were about fungal taxonomy image:Hierarchical clustering diagram.png, 2 ...

Taxa Named By Christopher Edmund Broome
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haustoria
In botany and mycology, a haustorium (plural haustoria) is a rootlike structure that grows into or around another structure to absorb water or nutrients. For example, in mistletoe or members of the broomrape family, the structure penetrates the host's tissue and draws nutrients from it. In mycology, it refers to the appendage or portion of a parasitic fungus (the hyphal tip), which performs a similar function. Microscopic haustoria penetrate the host plant's cell wall and siphon nutrients from the space between the cell wall and plasma membrane but do not penetrate the membrane itself. Larger (usually botanical, not fungal) haustoria do this at the tissue level. The etymology of the name corresponds to the Latin word '' haustor'' meaning ''the one who draws, drains or drinks'', and refers to the action performed by the outgrowth. In fungi Fungi in all major divisions form haustoria. Haustoria take several forms. Generally, on penetration, the fungus increases the surface ar ...

Ascomycota
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the "ascus" (), a microscopic sexual reproduction, sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of Ascomycota are Asexual reproduction, asexual and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, yeast#Beer, brewers' and bakers' yeast, Xylaria, dead man's fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed "ascolichens") such as ''Cladonia'' belong to the Ascomycota. Ascomycota is a monophyletic group (containing all of the descendants of a common ancestor). Previously placed in the Basidiomycota along with asexual species from other fungal taxa, asexual (or Teleomorph, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sporocarp (fungi)
The sporocarp (also known as fruiting body, fruit body or fruitbody) of fungi is a multicellular structure on which spore-producing structures, such as basidia or asci, are borne. The fruitbody is part of the sexual phase of a fungal life cycle, while the rest of the life cycle is characterized by vegetative mycelial growth and asexual spore production. The sporocarp of a basidiomycete is known as a ''basidiocarp'' or ''basidiome'', while the fruitbody of an ascomycete is known as an '' ascocarp''. Many shapes and morphologies are found in both basidiocarps and ascocarps; these features play an important role in the identification and taxonomy of fungi. Fruitbodies are termed ''epigeous'' if they grow on the ground, while those that grow underground are '' hypogeous''. Epigeous sporocarps that are visible to the naked eye, especially fruitbodies of a more or less agaricoid morphology, are often called mushrooms. Epigeous sporocarps have mycelia that extend underground ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pucciniomycotina
Pucciniomycotina is a subdivision of fungus within the division Basidiomycota. The subdivision contains 10 classes, 21 orders, and 38 families. Over 8400 species of Pucciniomycotina have been described - more than 8% of all described fungi. The subdivision is considered a sister group to Ustilaginomycotina and Agaricomycotina, which may share the basal lineage of Basidiomycota, although this is uncertain due to low support for placement between the three groups. The group was known as Urediniomycetes until 2006, when it was elevated from a class to a subdivision and named after the largest order in the group, Pucciniales. Morphology There is a high morphological diversity in the Pucciniomycontina. The sporulating forms range from macrobasidiocarp to single-celled yeasts. The presence of simple septal pores, and disc-like spindle pole bodies unites Pucciniomycotina and distinguishes it from the sister groups. The predominance of mannose in the cell walls is also a uniting f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DNA Sequences
A nucleic acid sequence is a succession of bases within the nucleotides forming alleles within a DNA (using GACT) or RNA (GACU) molecule. This succession is denoted by a series of a set of five different letters that indicate the order of the nucleotides. By convention, sequences are usually presented from the 5' end to the 3' end. For DNA, with its double helix, there are two possible directions for the notated sequence; of these two, 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 represents genetic 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cladistic
Cladistics ( ; from Ancient Greek 'branch') 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 ...

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 phylogenetics, 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 (biology), 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 tre ...
