Study Notes
Fungi Overview
- Fungus is a Latin word meaning mushroom
- Mycology is the study of fungi, including their structure, reproduction, physiology, and taxonomy.
General Characteristics of Fungi
- Habitat: Fungi are found in many habitats with organic matter, including terrestrial, aquatic, pathogenic, and as contaminants.
- Mode of Life/Nutrition: Fungi are heterotrophic, meaning they lack chlorophyll and absorb ready-made nutrients from external sources. This can be saprophytic (on dead organic matter), parasitic (on living organisms), or symbiotic (in association with other organisms).
- Structure: Fungi can be unicellular (e.g., yeast) or multicellular (e.g., molds). Multicellular fungi have hyphae, which may be septate (with cross walls) or aseptate.
- Reproduction: Fungi reproduce both asexually (fragmentation, fission, budding, spore formation) and sexually (plasmogamy, karyogamy, meiosis).
- Classification: Fungi are classified based on their spores. Major divisions include Zygomycota, Ascomycota, and Basidiomycota.
Division Zygomycota
- Zygomycota are zygote-forming fungi.
- Zygospores are formed in a round case called sporangium.
- Examples include Mucor, Rhizopus (bread mold), and Albugo.
Division Ascomycota
- Sac fungi produce ascospores in cup-shaped sacs called asci.
- Ascospores are released when the ascus breaks open.
- Yeast is a common one-celled fungus that reproduces by budding.
- Examples include Aspergillus, Penicillium, morels, truffles, cup fungi, and powdery mildews.
Division Basidiomycota
- Basidiospores are borne on a club-shaped spore case called a basidium.
- Basidiomycota includes mushrooms, puffballs, and toadstools.
- In mushrooms, basidia are often located on gills under the cap.
- An average-sized mushroom produces billions of spores.
- Examples include Agaricus (mushroom), Ustilago (smut), and Puccinia (rust fungus).
Importance of Fungi
- Recycling: Fungi, along with bacteria, recycle dead organic matter.
- Edible Fungi: Many mushrooms are edible and cultivated for food.
- Medicines: Some fungi produce antibiotics like penicillin.
- Bio-control Agents: Fungi can be used to control pests and insects.
- Harmful Fungi: Some fungi cause food spoilage (e.g., aflatoxins) and plant/animal diseases (e.g., powdery mildew, rusts). Fungi also cause superficial infections like ringworm and tinea versicolor.
