What phylum is Myxomycota?


Why are slime molds called Myxomycota?

Myxomycota. Members of this division are commonly referred to as slime molds. Although presently classified as Protozoans, in the Kingdom Protista, slime molds were once thought to be fungi (=kingdom Mycetae) because they produce spores that are borne in sporangia, a characteristic common to some taxa of fungi.

Why Myxomycota and Oomycota are not placed in kingdom fungi?

However, they are no longer classified as fungi because of various non-fungal characteristics such as cell walls that are composed of cellulose rather than chitin, their life cycle being gametic rather than zygotic and their biflagellate zoospores, with one whiplash flagellum and one tinsel type flagellum, i.e. they …

What is the difference between phylum Myxomycota and phylum Acrasiomycota?

Slime molds are organisms in two taxonomic groups, the cellular slime molds (Phylum Acrasiomycota) and the plasmodial slime molds (Phylum Myxomycota). Organisms in both groups are eukaryotic (meaning that their cells have nuclei) and are fungus-like in appearance during part of their life cycle.

Is Myxomycota a fungus?

The Myxomycota or slime molds, are fungus-like organisms. They are characterised by the absence of cell wall from their amoeboid,’ animal-like vegetative or assimilatory phase. 4F) or amoeboid cells interconnected by slime filaments giving rise to a structure known as net plasmodium or filoplasmodium (Fig. 4G).

What is the function of Myxamoebae?

In its creeping phase it resembles an amoeba and is known as a myxamoeba. Both swarm cells and myxamoebae function as sex cells (gametes), and the fusion of two such cells constitutes the reproductive act of myxomycetes that begins the next stage of growth, the plasmodium.

How are slime molds classified?

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 referred to as kingdom Protista. When food is abundant, these slime molds exist as single-celled organisms.

What are the three types of slime molds?

Mycetozoa include the following three groups: Myxogastria or myxomycetes: syncytial, plasmodial, or acellular slime molds. Dictyosteliida or dictyostelids: cellular slime molds. Protosteloids: amoeboid slime-molds that form fruiting bodies.

Are Ascospores asexual?

The Ascomycota bear their sexual spores (ascospores) internally in sacs called asci, which are usually cylindrical. Many members also form conidia as asexual spores.

What does Myxamoebae meaning?

Myxamoebae are spores released from a slime mold that possess pseudopodia (lobes of cellular material) and are known for their amoeba-like appearance and behaviour.
