Slime Molds

Phylum Mycetozoa 

  • Organisms with an amoeba-like structure (=plasmoidial)
    • fungal-like protists: heterotrophic 
  • May represent ancestral protist with sexual reproduction 
    • Possibly diplontic or haplo-diplontic
    • diploid plasmodium is observable as feeding phase
  • Plasmodium: macroscopic, coenocytic mass, without cells walls 
  • Sclerotium: encrusting phase when env't conditions become unfavorable
  • Sporangial stage forms when conditions favorable
  • e.g. Physarum
Geologic Age: ??? - present


Unikonta - single flagellum organisms
Kingdom Amoebozoa - amoeba-like organisms
Phylum Mycetozoa - slime molds
Class Myxomycota - Plasmoidal slime molds
Class Dictyostelia - Cellular slime molds (non covered in class)
