Fungi Flashcards
Ascomycota
Blue-green red and brown food spoilage, mold, truffles, grows underground, powdery mildews, chestnut blight, dutch elm disease, yeasts, morels, ergot.
Characterized by spore production in sacs(asci)each bearing 8 spores
Zygomycota/Zygomycetes
Bread molds,pilobolus
Characterized by a resting sexual diploid phase,the zygosporangium, and spores produced in sporangia at the tip of a slender stock. Can shoot spores up to 1m away.
Basidiomycota
Club fungi, mushrooms, puffballs, shelf fungi, stinkhorns, rusts, smuts. Characterized by the spores being borne in sets of 4 of a club-shaped structure(basidium)
Deuteromycetes
Imperfect fungi. Characterized by either having or lacking an undiscovered sexual phase. When the sexual phase is discovered, it is transferred to one of the other groups.
Penicillium, Aspergillus, ringworm, athlete’s foot, skin diseases
Making a mold farm
Get 1, 1 gallon ziplock bag. Place slice of bread, quarter of orange, and slice of cheese in bag. Moisten all contents. Fill with air and seal.
Setting up Pilobolus
Shooting fungus. Must pass through digestive tract of a pasture grazing herbivore. Put manure in clear plastic cup. Moisten slightly. Cover with clear plastic wrap. Cover with paper towel with small hole in middle.
Lichen Characteristics
Main structure is ascomycete fungus (heterotrophic). Living inside fungus is cyanobacteria.
Cyanobacteria benefit from the protective moist environment.
Fungus benefits from the foodstuffs manufactured by the algae.
Lichens are able to dry out and become dormant in extremely unfavorable conditions and then rehydrate and resume metabolic activity when conditions are better.
Types of Lichens
Crustose-Crusty looking
Foliose-Leafy Looking
Fruticose-Shrubby Looking
Mycorrhizae
Myco-Fungus
Rhizae-Root
Fungi benefits from receiving food/sugar
Plant benefits from root extension; can grow longer, faster, and in a larger area for more uptake of water and nutrients
