Cellular
individual amoebae that aggregate and form more complex structures
plasmodial
single, multinucleate large cell
Amoeba
all described slime molds have this phase, typically uninucleate, unicellular, no cell wall, phagocytosis
sorocarp
cellular slime mold fruiting body
sporocarp
plasmodial slime mold fruiting body
Labyrinthulids (net slime molds)
produces slimeways as tracks for cells to glide along, biflagellate zoospores, most marine or estuarine (rarely freshwater), saprobes parasites
Labyrinthula terrestris
rapid blight on turf, occurs due to buildup of sodium, infection through leaf wounds, problematic in golf courses
Labyrinthula zosterae
eelgrass wasting disease, asymptomatic until plant gets stressed, interferes with photosynthesis, outbreak in 1930s killed 90% of eelgrass
Plasmodiophora (endoparasitic slime molds)
multinuculate wall-less protoplasts, cannot move, no phagocytosis, live entirely inside host cells, biflagellate zoospores necrotrophic parasites of vascular plants, hypertrophy and hyperplasia
plasmodiophora brassicae
clubroot of cabbage
Spongospora subterranea
powdery scab of potatoes
Acrasida (acrasid cellular slime molds)
aggregate behavior, moist soil, organic debris, dung, eats bacteria, yeasts, and decaying vegetation
Dictyostelids - cellular slime molds
when they run out of food they aggregate, forming pseudoplasmodium with cAMP, and move as a slug to optimal spore dispersal location
Dictyosteloim discoideum
model organism, entire cycle completed in one day
myxogastrids - plasmodial slime molds
no cell wall, can switch between biflagellated and non flagellated body forms,
Physarum polyceophalum
external spatioal memory similar to pheromone trail for ants but made of slime
sporangium
several to many stalked or unstalked spore masses that are sepatrate but formed from a common plasmodium
Plasmodiocarp
a spore mass that remains connected and retains the shape of the plasmodium
Aethalium
a cushion or puffball shaped sporocarop where almost all of the tissues become spores
pseudoaethalium
composite structure composed of several sporangia massed together
capillitium
thick hyphal-like cords that provide structure and retain the spores for wind dispersal made by caco3 in slime molds
Fuligo septica
dog vomit slime mold
Protostelia
formplasmodia and some can form swarmers
Ceratiomyxa fruticulosa
one of the most common slime molds
