Definition

Noun: - A taxonomic subdivision of fungi characterized by motile spores and gametes. In some older classification systems, it was grouped within the Phycomycetes alongside the Zygomycota.

Usage
  • This term is used in the scientific field of mycology (the study of fungi) to classify a specific group of organisms based on their reproductive structures.
  • It is primarily found in academic, taxonomic, or biological texts.
Examples
Advanced Usage
  • The classification "Mastigomycota" is historical. Modern phylogenetic systems often do not use this subdivision, having reclassified its members into more precise groups like the Oomycota or Chytridiomycota based on DNA analysis.
  • It is often discussed in contrast to other fungal subdivisions like Zygomycota or Ascomycota, which lack motile spores.
Variants and Related Words
  • Mastigomycota (noun): The same taxonomic group; often used without "subdivision."
  • Mastigomycotina (noun): A synonymous term for the same subdivision in some classification schemes.
  • Zoosporic fungi (noun): A descriptive term for fungi producing motile zoospores, encompassing members historically placed in Mastigomycota.
Synonyms
  • Zoosporic fungi (descriptive synonym)
  • Flagellated fungi (descriptive synonym)
Notes on Meaning
  • The core defining feature is motility in reproductive cells (spores and gametes), typically via flagella.
  • It represents a paraphyletic grouping, meaning it includes some, but not all, descendants of a common ancestor, which is why its use has declined in modern taxonomy.
Noun
  1. fungi in which the spores and gametes are motile; in some systems placed in the Phycomycetes group with the Zygomycota
