Emil Müller (mycologist)
Emil Müller (March 5, 1920 – April 2, 2008) was a Swiss mycologist. He specialised in the study of the systematics of the ascomycetes. Müller was the editor of the scientific journal ''Sydowia'' for several years, taking over the position after the death of the previous editor and founder, Franz Petrak, in 1973. Müller published more than 200 papers in his scientific career. He was well known in the mycological community for two taxonomic publications co-authored with his colleague J.A. von Arx: ''Die Gattungen der amerosporen Pyrenomyceten'' (Genera of the amerosporous Pyrenomycetes, 1954) and ''Die Gattungen der didymosporen Pyrenomyceten'' (Genera of didymosporous Pyrenomycetes, 1962). In 1968, botanist Lennart Holm published '' Muellerites'', which is a genus of fungi in the class Dothideomycetes and named after Emil. Then in 1968, '' Muelleromyces'' (the family Phyllachoraceae) was published. See also *List of mycologists This is a non-exhaustive list of mycologists, ...

Mycologist
Mycology is the branch of biology concerned with the study of fungus, fungi, including their genetics, genetic and biochemistry, biochemical properties, their Taxonomy (biology), taxonomy and ethnomycology, their use to humans, including as a source for tinder, traditional medicine, Edible mushroom, food, and entheogens, as well as their dangers, such as poison, toxicity or fungal infection, infection. A biologist specializing in mycology is called a mycologist. Mycology branches into the field of phytopathology, the study of plant diseases, and the two disciplines remain closely related because the vast majority of plant pathogens are fungi. Overview Historically, mycology was a branch of botany because, although fungi are evolutionarily more closely related to animals than to plants, this was not recognized until a few decades ago. Pioneer mycologists included Elias Magnus Fries, Christian Hendrik Persoon, Anton de Bary, Elizabeth Eaton Morse, and Lewis David von Schweinitz ...

Systematics
Biological systematics is the study of the diversification of living forms, both past and present, and the relationships among living things through time. Relationships are visualized as evolutionary trees (synonyms: cladograms, phylogenetic trees, phylogenies). Phylogenies have two components: branching order (showing group relationships) and branch length (showing amount of evolution). Phylogenetic trees of species and higher taxa are used to study the evolution of traits (e.g., anatomical or molecular characteristics) and the distribution of organisms (biogeography). Systematics, in other words, is used to understand the evolutionary history of life on Earth. The word systematics is derived from the Latin word '' systema,'' which means systematic arrangement of organisms. Carl Linnaeus used 'Systema Naturae' as the title of his book. Branches and applications In the study of biological systematics, researchers use the different branches to further understand the relationshi ...

Ascomycetes
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 structure in which nonmotile spores, called ascospores, are formed. However, some species of the Ascomycota are asexual, meaning that they do not have a sexual cycle and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, brewers' and bakers' yeast, 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 (it contains all descendants of one common ancestor). Previously placed in the Deuteromycota along with asexual species from other fungal taxa, asexual (or anamorphic) ascomycetes ...

Sydowia (journal)
''Sydowia'' is a biannual peer-reviewed scientific journal covering the study of fungi, including their taxonomy, systematics, evolution, structure, development, ecology, pathology in plants, animals, and humans, and biotechnological applications. It is published by Verlag Ferdinand Berger & Söhne. Its editor in chief is Irmgard Krisai-Greilhuber. History The journal was originally established in 1903 under the title ''Annales Mycologici'' by founding editor Hans Sydow. It was continued as ''Annales mycologici, series II'' and retitled with the prefix ''Sydowia'' in Sydow's honour following his death in 1946. ''Sydowia'' was edited by Franz Petrak from 1947 until his death in 1973. Egon Horak succeeded him until 1989. Orlando Petrini took over from 1989 to 1996 and Liliane Petrini until 2004. ''Sydowia'' was published bimonthly from 1947 and biannually since 1992. Now published in English, earlier volumes included papers in English, French, German, Italian, Latin, and Spanish ...

Franz Petrak
Franz Petrak (9 October 1886, Mährisch-Weißkirchen – 9 October 1973, Vienna) was an Austrian-Czech mycologist. From 1906 to 1910, he studied botany at the University of Vienna, where he was a student of Richard Wettstein. In 1913 he obtained his doctorate of sciences, and until 1916, worked as a high school teacher in Vienna. During World War I, he was stationed in Galicia and Albania, where he collected specimens in his spare time. From 1918 to 1938, he worked as a private scientist in his home town, and from 1938 to 1951, was associated with the Naturhistorisches Museum in Vienna. He was the author of nearly 500 published works, primarily in the field of mycology. Much of his mycological work was published in the journal ''Annales mycologici'' and its successor ''Sydowia''. Reportedly, his private herbarium contained 100,000 specimens. As a taxonomist, he described numerous species within the genus ''Cirsium'' (family Asteraceae). The mycological genera of; '' Petrakia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...

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 ...

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] |
Dothideomycetes
Dothideomycetes is the largest and most diverse class of ascomycete fungi. It comprises 11 orders 90 families, 1300 genera and over 19,000 known species. Traditionally, most of its members were included in the loculoascomycetes, which is not part of the currently accepted classification. This indicates that several traditional morphological features in the class are not unique and DNA sequence comparisons are important to define the class. The designation loculoascomycetes was first proposed for all fungi which have ascolocular development. This type of development refers to the way in which the sexual structure, bearing the sexual spores (ascospores) forms. Dothideomycetes mostly produce flask-like structures referred to as pseudothecia, although other shape variations do exist (e.g. see structures found in Hysteriales). During ascolocular development pockets (locules) form first within the vegetative cells of the fungus and then all the subsequent structures form. These includ ...
