  1. Lab 5 Fungi

  2. Fungi • Common name: Fungi, molds • Synonyms: Eumycota • Mode of nutrition: Heterotrophic: saprophytic or parasitic • Habitat: Terrestrial, aquatic, or within host organism • Growth habit: Multicellular mycelium, or unicellular • Cell wall: Chitin

  3. Fungi • Undulipodia (“flagella”): Two whiplash, or none • Food storage: Glycogen • Clonal reproduction: Aplanospores, zoospores • Sexual reproduction: Haploid-dominant; alternation of generations • Included Phyla: Chytridiomycota, Zygomycota, Ascomycota, Basidiomycota • Recognized by: Chitin cell wall, saprophyte or parasite.

  4. Chytridiomycota • General features of the Fungi • Common name: Chytrids • Synonyms: None • Habitat: Freshwater or within host organism (which may be a terrestrial plant) • Growth habit: Unicellular or multicellular mycelium of aseptate hyphae • Undulipodia (“flagella”): Whiplash, often two

  5. Chytridiomycota • Clonal reproduction: Zoospores • Sexual reproduction: Haploid-dominant, isomorphic alternation of generations - isogamous or anisogamous • Representative genera: Allomyces, Synchytrium • Recognized by: Flagellated cells, chitin cell walls

  8. AAllomyces sporophyte Chytridiomycota

  9. Zygomycota • General features of the Fungi • Common name: Bread molds • Synonyms: Phycomycota (also applied incorrectly in old references to the Oomycota) • Habitat: Terrestrial or within host organism • Growth habit: Multicellular mycelium of aseptate hyphae, or unicellular

  10. Zygomycota • Undulipodia (“flagella”): None • Clonal reproduction: Aplanospores • Sexual reproduction: Haploid-dominant, isogamous • Representative genera: Phycomyces, Rhizopus • Recognized by: Zygospores; clonal spores inside sporangia

  11. ARhizopus Zygomycota

  12. URhizopus Zygomycota

  14. Ascomycota • General features of the Fungi • Common name: Sac fungi • Synonyms: None • Habitat: Terrestrial or within host organism; rarely freshwater or marine • Growth habit: Multicellular mycelium of septate hyphae, or unicellular • Undulipodia (“flagella”): None

  15. Ascomycota • Clonal reproduction: conidia • Sexual reproduction: Haploid-dominant, often characterized as oogamous • Representative genera: Anthracobia, Aspergillus, Erisyphe, Penicillium, Peziza, Saccharomyces, Sordaria, Taphrina, Uncinula • Recognized by: Asci, open pores in septa
