Study Notes
Chytridiomycota
- Mostly aquatic fungi with flagellated spores called zoospores
- Exhibit both sexual and asexual reproduction
- Examples:
- Allomyces - a water mold chytrid
- Batrachytium dendrobatidis - causes chytridiomycosis in amphibians
Zygomycota
- Form zygospores, which are reproductive structures capable of surviving harsh conditions
- Zygospores form during sexual reproduction
- Terrestrial fungi that depend on decaying material
- Have coenocytic hyphae (multinucleated)
- Examples:
- Rhizopus stolonifer - black bread mold
- Pilobolus - grows on dung
Glomeromycota
- Form arbuscular mycorrhizal associations with plant roots for nutrient exchange, a mutualistic relationship
- Reproduction through multinucleated spores
- Example: Glomus
Ascomycota (Sac Fungi)
- Form asci, sac-like structures containing sexual spores (ascospores)
- Also produce asexual spores called conidia
- Examples:
- Saccharomyces cerevisiae - baker's yeast
- Penicillium - produce antibiotics
- Aspergillus - used in fermentation, some are pathogenic
Basidiomycota (Club Fungi)
- Form basidia, club-shaped structures that contain spores
- Typically have complex life cycles with both asexual and sexual stages
- Examples:
- Agaricus bisporus - edible mushrooms
- Ustilago maydis - corn smut
- Ganoderma lucidum - used in traditional medicine
Deuteromycota (Fungi Imperfecti)
- Lack a known sexual reproduction phase (anamorphic fungi)
- Reproduce asexually through conidia
- Examples:
- Candida albicans
- Aspergillus niger - produces citric acid
Lichens
- Symbiotic association between fungi (usually Ascomycota) and photosynthetic organisms (algae)
- Used as bioindicators
