Biosci 221 - Fungi

Fungi are

chemoheterotrophic

Mycoses

fungal infections which can be caused by inhalation or contact with asexual spores

hyphae

long, threadlike filaments

mycelia

mass of hyphae

septate

having walled divisions along the hyphae

aseptate

no walled divisions along the hyphae

asexual spores

conidia and sporangiospores

conidia

not in a sac; extend from the hyphae

sporangiospores

enclosed in a sac

sexual spores

ascospores, basidiospores, zygospores

yeast

single-celled fungi

molds

multi-celled; made up of hyphae

dimorphic

having a yeast and a mold stage

*Rhizopus*

Zygomycota

sporangiospores

aseptate

bread mold

dimorphic

saprophytic

*Aspergillus*

Ascomycota

conidia

very common airborne soil fungus

dimorphic

septate

Farmer’s Lung

*Penicillium*

Ascomycota

conidia

dimorphic

septate

*Coprinus*

Basidiomycota

septate

*Pezziza*

Ascomycota

conidia

septate

saprophytic

*Candida albicans*

Ascomycota

budding

lives on your body (skin, GI and vaginal tract, and oral cavity)

dimorphic yeast

septate

candidal intertrigo and candida thrush

*Coccidioides immitis*

Ascomycota

segmentation of hyphae produces arthrospores and can be inhaled

windy conditions spread its fungal spores easily

dimorphic

saprophytic

septate

Valley Fever

*Saccharomyces cerevisiae*

Ascomycota

budding

dimophic

aseptate

Brewer’s/Baker’s yeast
