slime molds; organisms having a noncellular and multinucleate creeping vegetative phase and a propagative spore-producing stage: comprises Myxomycetes. Two distinct phases occur in the life-cycle of a slime-mould. First there is an active assimilative phase in which the thallus, a protozoa-like amoeboid plasmodium.

Olive myxomjcota the group under the Kingdom Protista and divided them into seven classes: Alexopoulos divided the class Myxomycetes into three subclasses: Olive LS The Mycetozoa: Patterns of occurrence on bark surface of living trees, leaf litter, and dung.
Stephenson SL From morphological to molecular: The thallus forms net plasmodium or filoplasmodium. Ein beitrag zur Kenntnis der niedersten thiere. Approximately species of myxomycetes have been described, but the concept of species as used for many of the more familiar groups of organisms is often rather problematic.
Labyrinthula macrocystis is a very common species, found as parasite on Zostera marina, the eel-grass. Meiosis takes place during spore formation in the fructification.
Madelin MF Myxomycetes, microorganisms and animals: Later, Olive raised the rank subclasses into classes as Protosteliomycetes, Acrasiomycetes and Dictyosteliomycetes. The filaments are tubular and form net-like structure, the net-plasmodium or filoplas- modium. Here’s how it works: Ceratio- myxomycetidae, Myxogastromycetidae and Stemonitomycetidae.
The British Mycological Society. Fusion of two compatible amoeboflagellates to produce a single cell. University of Iowa Studies in Natural History Mature fruiting bodies with spores still enclosed. Martin also treated slime molds as Myxomycetes under fungi and fivision according to him has a protozoan ancestry.
Division Myxomycota: History, Characteristics and Classification
Image produced by Randy Darrah. Protosteliomycetes, Ceratomyxo- mycetes, Dictyosteliomycetes, Acrasiomycetes, Myxomycetes, Plasmodiophoromycetes and Labrinthulomycetes. He divided the class into 3 subclasses: Portion of a mature plasmodium. The class consists of a single order Plasmodiophorales with a single family Plasmo- diophoraceae.
This was followed by different scientists for long time. However, there is now abundant molecular data to confirm that they are amoebozoans and not fungi.

The class consists of 16 genera and 45 species. They resemble the primitive fungi in their mode of reproduction by producing spores within sporangia.
