Fungi

Molds

• Multicellular

• Present in soil and decaying matter

• Composed of hyphae

  • Can be septate or non-septate

Non-septate Hyphae

Walls are absent

Septate Hyphae

Walls separate adjacent cells

Vegetative Hyphae

• Metabolic function

• Absorbs nutrients from environment

Aerial Hyphae

• Reproductive function

• Produces spores

Dimorphic Fungi

Have both mold (multicellular) and yeast (unicellular) life stages

Yeast

• Unicellular

• Oval shaped

• Reproduce by budding

• Ex: baking and brewers yeast (S. Cereviseae)

Macrofungi

• produce fleshy reproductive structures

• Mushrooms, puffballs, shelf fungi

Ascomycota

• Sac fungi

• Septate hyphae

• Ex: Aspergillus, Yeast (Penicillium)

Zygomycota

• Non-septate hyphae

• Ex: Rhizopus

Basidiomycota

• Mushrooms

• Club fungi

Growing Fungi

• 7-10 days

• 20-25°C

• 4-6 pH

• Sabouraud’s agar
