Fungi

Mushrooms

yeasts

molds

smuts/rust

  • Multicellular or unicellular
  • Heterotrophic - Saprophytes (release enzymes to break down organic material)
  • Cell wall made of chitin
  • made of hyphae
  • begin life as a single-celled spore

2

Hyphae

  • Can form a mass called mycelium
  • Septate hyphae - separated by cross walls called septa
  • Coenocytic hyphae - no cross walls, continuous with multiple nuclei
  • Most fungi sexually reproduce by spores produced on fruiting bodies

3

Kingdom Fungi consists of 

  • Phylum Zygomycota
  • Phylum Ascomycota
  • Phylum Basidiomycota 

4

Phylum Zygomycota

  • Rhizopus stolonifer (black bread mold)
  • Asexual Reproduction: aerial hyphae called sporangiophores terminate in spore-bearing sporangia
  • Sexual reproduction triggered when env. conditions become unfavorable
  • (+/-) strains develop suspensors
  • Gametangia forms
  • fuse and become zygospore (diploid)

5

Phylum Ascomycota (sac fungi)

Peziza

  • Fruiting body ascocarp is formed after fusion of +/- hyphae
  • contains long thin cells called asci (ascus)
  • within each ascus, meiosis followed by mitosis results in 8 ascospores

6

​Lichens

  • a symbiotic relationship between a fungus and a phototroph
  • Include:
  • Crustose
  • Foliose
  • Fruticose

7

Crustose

8

Foliose

9

Fruticose

10

Phylum Basidiomycota (club fungus)

Coprinus

  • sexually reproduces between (+/-) strains of hyphae
  • basidiocarp is formed (fruiting body)
  • consists of cap, stalk, and gills
  • annulus (a ring of scar tissue)
  • Spore formation via meiosis within each gills on club-shaped  basidia
