Myxomycota

Myxomycota is a phylum of the Kingdom Amoebozoa related to protists. The name comes from the Greek Myxo, meaning "slime", and mycota, meaning fungus. They are also known as the plasmodial or acellular slime molds.

Some would also consider myxomycota as a kingdom unto itself, with an unsettled phylogeny because of conflicting molecular and developmental data.

Reproduction
Myxomycota can form swarm cells that aggregate, fuse, form a sporangia, sporulate, and return to amoebal or swarm cell stages. The Myxomycota themselves are haploid, and can switch between amoeboid and flagellated forms. The gametes fuse into a zygote, which then becomes a plasmodium, which can produce fruit-like spores.
