Nucleariid
Nucleariida is a group of amoebae with filose pseudopods, known mostly from soils and freshwater. They are distinguished from the superficially similar vampyrellids mainly by having mitochondria with discoid cristae, in the absence of superficial granules, and in the way they consume food. Classification Molecular studies indicate that nucleariids are closely related to fungi. and more distantly to the lineage that gave rise to choanoflagellates and metazoa opisthokonts, the group which includes animals, fungi. Some use a broad definition of Opisthokonta to include all of these organisms with flattened mitochondrial cristae. The genera ''Rabdiophrys'', ''Pinaciophora'', and ''Pompholyxophrys'', freshwater forms with hollow siliceous scales or spines, were included in Nucleariida by some. This was disputed by Smith and Chao who placed them in the Rhizaria. Their affinity with the nucleariids has been confirmed. Historically, nucleariids were included among the heliozoa as the ...

Vampyrellidae
The family Vampyrellidae is a subgroup of the order Aconchulinida (formerly Vampyrellida) within the phylum Cercozoa. Based on molecular sequence data, the family currently comprises the genus ''Vampyrella'', and maybe several other vampyrellid amoebae (e.g. ''Gobiella''). The cells are naked and characterised by radiating, filose pseudopodia (also referred to as filopodia) and an orange colouration of the main cell body. In former times the family Vampyrellidae contained several genera (e.g. ''Vampyrella'', ''Gobiella'', ''Leptophrys'', ''Platyreta'', ''Theratromyxa'') and was identical with the order Vampyrellida West, 1901, also known under the name "Aconchulinida". However, based on molecular sequence data it seemed reasonable to restrict the family Vampyrellidae to a subgroup (containing the genus ''Vampyrella'') and to establish another family for the genera ''Leptophrys'', ''Platyreta'' and ''Theratromyxa'', namely the Leptophryidae Hess et al., 2012.

Micronuclearia
''Micronuclearia'' is a genus of free-living protozoa. While originally thought to be a nucleariid Nucleariida is a group of amoebae with filose pseudopods, known mostly from soils and freshwater. They are distinguished from the superficially similar vampyrellids mainly by having mitochondria with discoid cristae, in the absence of superfi ..., as reflected in the name, it is now inferred to be a member of the taxon Rigifilida, and to belong to the 'CRuMs' assemblage (whereas nucleariids are opisthokonts). The type species is '' Micronuclearia podoventralis''. References Podiata Eukaryote genera {{eukaryote-stub ...

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 ...

Heliozoa
Heliozoa, commonly known as sun-animalcules, are microbial eukaryotes (protists) with stiff arms ( axopodia) radiating from their spherical bodies, which are responsible for their common name. The axopodia are microtubule-supported projections from the amoeboid cell body, and are variously used for capturing food, sensation, movement, and attachment. They are similar to Radiolaria, but they are distinguished from them by lacking central capsules and other complex skeletal elements, although some produce simple scales and spines. They may be found in both freshwater and marine environments. Classification Originally the heliozoa were treated together as a formal taxon Heliozoa or Heliozoea, with the rank of class or phylum, but it has been realised that they are polyphyletic, as the various orders show notable differences and are no longer believed to be descended from a single common ancestor. Instead, "heliozoa" is regarded as a descriptive term applying to various lines of proti ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Slime Mold
Slime mold or slime mould is an informal name given to several kinds of unrelated eukaryotic organisms with a life cycle that includes a free-living single-celled stage and the formation of spores. Spores are often produced in macroscopic multicellular or multinucleate fruiting bodies which may be formed through aggregation or fusion. Slime molds were formerly classified as fungi but are no longer considered part of that kingdom. Although not forming a single monophyletic clade, they are grouped within the paraphyletic group Protista. More than 900 species of slime mold occur globally. Their common name refers to part of some of these organisms' life cycles where they can appear as gelatinous "slime". This is mostly seen with the Myxogastria, which are the only macroscopic slime molds. Most slime molds are smaller than a few centimetres, but some species may reach sizes up to several square metres and masses up to 20 kilograms. They feed on microorganisms that live in ...

Fonticula
''Fonticula'' is a genus of cellular slime mold which forms a fruiting body in a volcano shape. As long ago as 1979 it has been known to not have a close relationship with either the Dictyosteliida or the Acrasidae, the two well-established groups of cellular slime molds. In 1979, ''Fonticula'' was made a new genus of its own due to the unique characteristics of its fruiting body, with only one species: ''Fonticula alba''. The life cycle of ''Fonticula alba'' alternates between an amoeboid vegetative stage and aggregative fruiting stage. The fruiting body of the genus has a unique shape, as its sorocarp resembles a volcano and sorus looks like a ball of hot lava emerging from that volcano. Molecular phylogenies have found alignments in genes of ''Fonticula alba'' to subgroups in Opisthokonta. A 2009 study has found that ''Fonticula'' is the sister taxa to ''Nuclearia'', thus making it related to the kingdom Fungi. ''Fonticula'', ''Nuclearia'', and Fungi have been united into ...
