Ceratiomyxa Morchella
''Ceratiomyxa'' is a genus of plasmodial slime mould within the Eumycetozoa, first described by Pier Antonio Micheli. They are widely distributed and commonly found on decaying wood. The plasmodium often appears as white frost-like growth or thin watery layers on wood. Pillar or wall-like sporangia bud from the plasmodium and develop spores that undergo multiple divisions before they release flagellated zoospores. The zoospores will then pair off, undergo plasmogamy, and form zygotes that will later form new plasmodia. The genus currently contains 4 species. The most notable member is ''Ceratiomyxa fruticulosa,'' a slime mould found in most parts of the world. Other known species of ''Ceratiomyxa'' are mostly found in the tropics. Etymology ''Ceratiomyxa'' comes from the Latin word ''ceratus'' meaning "waxed" and the ancient Greek word ''myxa'' meaning "mucus". History of knowledge ''Ceratiomyxa'' was first described under the name ''Puccinia ramose'' (later revised to '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eukaryota
The eukaryotes ( ) constitute the Domain (biology), domain of Eukaryota or Eukarya, organisms whose Cell (biology), cells have a membrane-bound cell nucleus, nucleus. All animals, plants, Fungus, fungi, seaweeds, and many unicellular organisms are eukaryotes. They constitute a major group of Outline of life forms, life forms alongside the two groups of prokaryotes: the Bacteria and the Archaea. Eukaryotes represent a small minority of the number of organisms, but given their generally much larger size, their collective global biomass is much larger than that of prokaryotes. The eukaryotes emerged within the archaeal Kingdom (biology), kingdom Asgard (Archaea), Promethearchaeati and its sole phylum Promethearchaeota. This implies that there are only Two-domain system, two domains of life, Bacteria and Archaea, with eukaryotes incorporated among the Archaea. Eukaryotes first emerged during the Paleoproterozoic, likely as Flagellated cell, flagellated cells. The leading evolutiona ...

Amoebozoa
Amoebozoa is a major Taxonomy (biology), taxonomic group containing about 2,400 described species of Amoeba, amoeboid protists, often possessing blunt, fingerlike, Pseudopod#Morphology, lobose pseudopods and tubular mitochondrial cristae. In traditional classification schemes, Amoebozoa is usually ranked as a phylum within either the kingdom (biology), kingdom Protista or the kingdom Protozoa. In the classification favored by the International Society of Protistologists, it is retained as an unranked "supergroup (biology), supergroup" within Eukaryota. Molecular genetics, Molecular genetic analysis supports Amoebozoa as a monophyletic clade. Modern studies of eukaryotic phylogenetic trees identify it as the sister group to Opisthokonta, another major clade which contains both fungi and animals as well as several other clades comprising some 300 species of unicellular eukaryotes. Amoebozoa and Opisthokonta are sometimes grouped together in a high-level taxon, named Amorphea. Amoeboz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protostelia
''Protostelium'' is a genus of protosteloid amoebozoans, i.e., amoebae capable of forming simple fruiting bodies composed of a stalk and a ball of spores. It contains numerous species, including '' P. aurantium'', which was initially classified in a different genus ''Planoprotostelium''. Phylogenetic analyses revealed that ''Planoprotostelium'' branches from within the genus ''Protostelium'', making them synonyms. The genus is placed in the family Protosteliidae within the monotypic order Protosteliida, which is part of a larger group of amoebozoans known as Variosea. Classification Many species from the genus ''Protostelium'' have been transferred over time to other protosteloid genera. The following species remain: * ''Protostelium apiculatum'' * ''Protostelium aurantium'' (=''Planoprotostelium aurantium'' ) * ''Protostelium mycophaga'' * ''Protostelium nocturnum'' * ''Protostelium okumukumu ''Protostelium okumukumu'' is a species of ''Protostelium'' found in Hawaii and N ...

Joseph Schröter
Joseph Schröter (14 March 1837 – 12 December 1894) was a German mycologist and medical doctor. He wrote several books and texts, and discovered and described many species of flora and fungi. He also spent around fifteen years, from 1871 to 1886, as a military doctor, particularly in the Franco-Prussian War, in places such as Spandau, Rastatt and Breslau, and rising to the rank of colonel. Life In 1855 Schröter chose to study medicine in Breslau, Lower Silesia (Wrocław, Poland since 1945), but in 1856, he transferred to the Friedrich-Wilhelm Academy in Berlin, Prussia (Germany did not unite into a single nation state until 1871). In 1859 he earned his Doctor of Medicine degree. In the same year, he enlisted in the Prussian army, serving as a doctor in the Franco-Prussian war. He occupied this post to the end of the war, in 1871, before being stationed at Spandau, and later Rastatt. For his efforts as a doctor, as well as the various other contributions he made to the militar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christian Hendrik Persoon
Christiaan Hendrik Persoon (31 December 1761 – 16 November 1836) was a Cape Colony mycologist who is recognized as one of the founders of mycology, mycological Taxonomy (biology), taxonomy. Early life Persoon was born in Cape Colony at the Cape of Good Hope, the third child of an immigrant Pomeranian father, Christiaan Daniel Persoon, and Netherlands, Dutch mother, Wilhelmina Elizabeth Groenwald. His mother died soon after he was born. In 1775, at the age of thirteen, he was sent to Europe for his education. His father died a year later in 1776. Education Initially a student of theology at University of Halle-Wittenberg, Halle, Persoon switched his studies to medicine, which he pursued in Leiden and then Göttingen. He received a doctorate from the German National Academy of Sciences Leopoldina, Deutsche Akademie der Naturforscher in Erlangen 1799. Later years He moved to Paris by 1803, where he spent the rest of his life, renting the upper floor of a house in a poor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
