Franz Xaver Rudolf Von Höhnel
Franz Xaver Rudolf von Höhnel (24 September 1852 – 11 November 1920) was an Austrian bryologist, mycologist, and algologist, brother of explorer Ludwig von Höhnel (1857–1942).Ronald E. Coons and Pascal James Imperato, eds. ''Over Land and Sea: Memoir of an Austrian rear Admiral's Life in Europe and Africa, 1857-1909.'' Holmes and Meier, New York, 2000. He obtained his PhD in Strasbourg in 1877, and was a professor of botany in the Vienna University of Technology from 1884 to 1920. Höhnel described roughly 250 new genera and 500 species of fungi, and was known for his contributions to the taxonomy of the Coelomycetes ( asexual fungi that form conidia in a cavity ( pycnidia) or a mat-like cushion of hyphae). He died in Vienna Vienna ( ; ; ) is the capital city, capital, List of largest cities in Austria, most populous city, and one of Federal states of Austria, nine federal states of Austria.

Sombor
Sombor ( sr-Cyrl, Сомбор, ; ; ) is a List of cities in Serbia, city and the administrative center of the West Bačka District in the autonomous province of Vojvodina, Serbia. The city has a total population of 41,814 (), while its administrative area (including neighboring villages) has 70,818 inhabitants. Name and etymology In Serbian language, Serbian, the city is known as ''Sombor'' (Сомбор), in Hungarian language, Hungarian as ''Zombor'', in Pannonian Rusyn language, Rusyn as ''Zombor'' (Зомбор). The older Hungarian name for the city was ''Czoborszentmihály''. The name originates from the Czobor family, who were the owners of this area in the 14th century. (The family name came from the Slavic name ''Cibor''.) The Serbian language, Serbian name for the city ''(Sombor)'' also came from the family name Czobor, and was first recorded in 1543, although the city was mentioned in historical documents under several more names, such as ''Samobor, Sambor, Sambir, ...

Fungi
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or 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 motility, 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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hypha
A hypha (; ) is a long, branching, filamentous structure of a fungus, oomycete, or actinobacterium. In most fungi, hyphae are the main mode of vegetative growth, and are collectively called a mycelium. Structure A hypha consists of one or more cells surrounded by a tubular cell wall. In most fungi, hyphae are divided into cells by internal cross-walls called "septa" (singular septum). Septa are usually perforated by pores large enough for ribosomes, mitochondria, and sometimes nuclei to flow between cells. The major structural polymer in fungal cell walls is typically chitin, in contrast to plants and oomycetes that have cellulosic cell walls. Some fungi have aseptate hyphae, meaning their hyphae are not partitioned by septa. Hyphae have an average diameter of 4–6 μm. Growth Hyphae grow at their tips. During tip growth, cell walls are extended by the external assembly and polymerization of cell wall components, and the internal production of new cell membrane. ...

Pycnidia
A pycnidium (plural pycnidia) is an asexual fruiting body produced by mitosporic fungi, for instance in the order Sphaeropsidales ( Deuteromycota, Coelomycetes) or order Pleosporales (Ascomycota, Dothideomycetes). It is often spherical or inversely pearshaped ( obpyriform) and its internal cavity is lined with conidiophore A conidium ( ; : conidia), sometimes termed an asexual chlamydospore or chlamydoconidium (: chlamydoconidia), is an Asexual reproduction, asexual, non-motility, motile spore of a fungus.

Conidia
A conidium ( ; : conidia), sometimes termed an asexual chlamydospore or chlamydoconidium (: chlamydoconidia), is an asexual, non- motile spore of a fungus. The word ''conidium'' comes from the Ancient Greek word for dust, ('). They are also called mitospores due to the way they are generated through the cellular process of mitosis. They are produced exogenously. The two new haploid cells are genetically identical to the haploid parent, and can develop into new organisms if conditions are favorable, and serve in biological dispersal. Asexual reproduction in ascomycetes (the phylum Ascomycota) is by the formation of conidia, which are borne on specialized stalks called conidiophores. The morphology of these specialized conidiophores is often distinctive between species and, before the development of molecular techniques at the end of the 20th century, was widely used for identification of (''e.g.'' '' Metarhizium'') species. The terms microconidia and macroconidia are some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teleomorph, Anamorph And Holomorph
In mycology, the terms teleomorph, anamorph, and holomorph apply to portions of the life cycles of fungi in the phyla Ascomycota and Basidiomycota: *Teleomorph: the sexual reproductive stage (morph), typically a fruiting body. *Anamorph: an asexual reproductive stage (morph), often mold-like. When a single fungus produces multiple morphologically distinct anamorphs, these are called synanamorphs. *Holomorph: the whole fungus, including anamorphs and teleomorph. The terms were introduced in 1981 to simplify the discussion of the procedures of the existing dual-naming system, which (1) permitted anamorphs to have their separate names but (2) treated teleomorphic names as having precedence for being used as the holomorphic name. The ''Melbourne Code'' removes the provisions and allows all names to compete on equal footing for priority as the correct name of a fungus, and hence does not use the term ''holomorph'' any more. Dual naming of fungi Fungi are classified primarily based o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomy (biology)
In biology, taxonomy () is the science, scientific study of naming, defining (Circumscription (taxonomy), circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxon, 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 (biology), domain, kingdom (biology), kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class (biology), class, order (biology), order, family (biology), family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, having developed a ranked system known as Linnaean taxonomy for categorizing organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transfo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
