FUNGI

KINGDOM FUNGI

• Nucleated

• Single celled

• Multicellular

• Sexual

• Asexual

• Heterotrophs – Saprotroph

– Parasites

– Symbiosis

MULTICELLUAR • Vegetative body made up of mycelium

• Mycelium made of filaments called hyphae

• Have cell-walls made of chitin

• Some cell separate by cell wall (septate hyphae) or they may be nonseptate.

• Hyphae secrete enzymes and absorb nutrients sometimes embedding in host or symbiotic pal

REPRODUCTION

• Asexual budding=yeast

• Asexual sporulative=spores

• Zygotic sporulative=spores

Phylum Zygomycota • Characterized by three types of hyphae

• Asexual and sexual spore reproduction

• Rhizopus stolonifer, BLACK BREAD MOLD

Rhizopus Slide

RHIZOPUS LIFE CYCLE

Phylum Ascomycota

• Characterized by tiny sac in which meiospores are formed called asci

• Mostly zygotic sporulative and multicellular but asexual budding in single celled yeast

• Yummy morels and truffles

• Penicillium=cheese and antibiotics

• Saprotrophs, symbiosis, and parasites (Dutch Elm Disease

• Fungi in Lichen (more to come)

Peziza

Penicillium

Yeast

Lichen=Symbiosis of Ascomycota and Green Algae

Foliose Fruticose Crustose

Lichen—Who’s who

Phylum Basidiomycota

• Called club fungi because of the basidia=terminal cells of reproductive hyphae

• Often zygotic sporulative reproduction

• Saprotrophs, symbiosis, and parasites (RUSTS!)

• Many of the mushrooms you recognize i.e. shelf, capped, puffballs etc.

Common Basidiomycota Anatomy

• Disregard Imperfect Fungi

• Do Assignment 1,2,3,4,and 6

• Use Cameras

• View Penicillium
