Dictydium Umbilicatum
''Cribraria'' is a genus of slime molds from the group of Myxogastria. It comprises about 30 species, some of which are extremely difficult to distinguish. Features The fruiting bodies are usually pedunculated sporangium, sporangia, a calyculus may be present or absent. The delicate peridium is reduced to a structure of vertical, thickened threads that are interconnected by extremely fine, translucent transverse threads.Michael J. Dykstra, Harold W. Keller: ''Mycetozoa'' In: ''Illustrated Guide to the Protozoa'', John J. Lee, Gordon F. Leedale, Phyllis Bradbury, Society of Protozoologists, 2nd edition, volume 2, pp. 952-981 In some cases, however, the peridium may also appear like a net, as in '' Cribraria '' - species. Mostly dark, clearly visible dictydine granules are found especially close to the ribs of the peridia, the calyculus and the spores.Marie L. Farr: ''Myxomycetes'', New York Botanical Garden, 1976, pp. 88-89 Distribution The genus is distributed worldwide, abo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amoebozoa
Amoebozoa is a major taxonomic group containing about 2,400 described species of amoeboid protists, often possessing blunt, fingerlike, lobose pseudopods and tubular mitochondrial cristae. In traditional and currently no longer supported classification schemes, Amoebozoa is ranked as a phylum within either the kingdom Protista or the kingdom Protozoa. In the classification favored by the International Society of Protistologists, it is retained as an unranked " supergroup" within Eukaryota. 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, variously named Unikonta, Amorphea or Opimoda. Amoebozoa includes many of the best-known amoeboid orga ...
