Fungus (pl. fungi)
  • Nutrition: heterotrophic (photosynthesis lacking) and absorptive (ingestion rare). No photosynthetic ability (heterotrophic nutrition)
  • Mode of life: saprophytic, parasitic, or symbiotic
  • Thallus: on or in the substratum and plasmodial amoeboid or pseudoplasmodial; or in the substratum and unicellular or filamentous (mycelial), the last, septate or nonseptate; typically nonmotile (with protoplasmic flow through the mycelium) but motile states (e.g., zoospores) may occur.
  • Cell wall: well-defined, typically chitinished (cellulose in Oomycetes).
  • Nuclear status: eukaryotic, multinucleate, the mycelium being homo or heterokaryotic, haploid, dikaryotic, or diploid, the last being usually of limited duration.
