History of Division Myxomycota 2. Stephenson SL Distribution and ecology of myxomycetes in temperate forests. Olive LS The Mycetozoans. This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. We have followed the classification of Ainsworth who placed them ymxomycota the division Myxomycota.
Nordic Journal of Botany 1: The British Mycological Society. Canadian Journal of Botany They are commonly aquatic and saprobic, but rarely parasitic.
The vegetative part consists of protoplast covered by plasma membrane and devoid of cell wall cell wall is present on the spore if produced by them. Fusion of two compatible amoeboflagellates to produce a single cell. This group is commonly known as true slime molds or plasmodial slime molds Fig.
The class consists of 16 genera and 45 species. Olive classified the group under the Kingdom Protista and divided them into seven myoxmycota Mitteilungen aus dem Geologischen Staatsinstitut in Hamburg Features and Occurrence Fungi. This group is commonly known as endo- parasitic slime molds.
The Myxomycota differs from true fungi because their vegetative body consists of only protoplast bounded by membrane and devoid of cell wall and also for their phagotrophic mode of nutrition. Myxomycetes are usually present and sometimes abundant in terrestrial ecosystems, where they are associated with various types of decaying plant materials e.

Division Myxomycota: History, Characteristics and Classification
This group shows uncertain affinities. Portion of a mature plasmodium. Sign myxomycora for e-alerts. Abstract The taxonomic division Myxomycota is made up of those eukaryotic microorganisms commonly referred to as the true slime moulds or as they are known to biologists myxomycetes.
Wasting time scanning endless search results for the right article? However, there is now abundant molecular data to confirm that they are amoebozoans and not fungi.
Myxomycetes have been recorded from every major type of terrestrial ecosystem examined to date, and at least a few species have been recovered from aquatic habitats microorganisms. Alexopoulos CJ The rapid sporulation of some myxomycetes in moist chamber culture.
