Explanation

Myxomycota constitutes first division of the kingdom fungi. These are distinguished from other fungi by the presence of a vegetative phase in their life cycle, which is devoid of cell wall and is either a free-living, multinucleate, amoeboid mass of protoplasm (Plasmodium) or an aggregation of amoebae in the form of slimy mass (during the vegetative phase), these are also called slime moulds. The spores are biflagellate in slime moulds.
