Large, thick, and cushion shaped
What do plasmodicarp son myxomycetes look like
Retain branching habit of the original plasmodium (most primitive)
What is the resting stage of plasmodial slime molds called
Sclerotium
What is a sclerotium
Resting stage for plasmodial slime molds that is a compacted mass of hardened mycelium with food reserves
What is a macro yet
Aggregation in the sclerotium and when environment is ideal an individual plasmodium will emerge (sort of like a seed in the sclerotium)
What is a key difference between myxomycetes and dictyosteliomycetes
Dictyo has cell wall

Pseudoplasmodium that is a motile slug like mass
What is the main function of the pseudoplasmodium of dictyosteliomycetes
To aggregate towards light or away from heat
