1. Classification of Fungi
Biology 112

2. How are fungi organized?
Fungi are organized according to their structure and function of reproduction
This makes them distinct from any other kingdom
How are fungi organized?

3. Common Molds Phylum Zygomycota (zygomycetes)
Have life cycles that includes a zygospore
A resting spore that contains zygotes
Formed by the sexual phase of the mold’s life cycle
Hyphae change in their structure over time
Reproduction occurs between different mating types that fuse and produce a gametangia
The zygote may remain dormant until favorable environmental conditions occur
New combinations of genetic variation occurs
Common Molds

4. Bread Mold (Rhizopus stolonifer)
Hyphae include:
Those that break the surface, called rhizoids
Those that run along the surface, called stolons
Bread Mold (Rhizopus stolonifer)

5. Sac Fungi Phylum Ascomycota Contain an ascus
a reproductive structure that contains spores
Largest phylum in the fungi kingdom
Includes asexual and sexual reproduction
Asexual: tiny spores called conidia form at the tips of specialized hyphae
Sexual: two different mating types form within the ascus of the fruiting body and combine
Sac Fungi

6. Yeasts Unicellular Dry yeast are ascospores (fertilized zygotes)
Reproduce asexually by budding
Yeasts

7. Club Fungi Phylum Basidiomycota
Contain a reproductive structure that resembles a club, or a basidiospore
Found on the gills on the underside of mushroom caps
Reproduction results in a fruiting body that produces spores which begins as a mass of hyphae referred to as a button
Club Fungi

8. Mushrooms/Club Fungi All club fungi are decomposers
Some may be parasites of plants and animals
Some are poisonous

9. Those fungi discovered by scientists who’s reproductive cycle is unknown
Most famous example is penicillium
