Mycology
Study of fungi
Thallus
Vegetative structure of fungi, lichens, or algae
Hyphae
Long, filamentous cells in fungi
Mycelium
Mass of hyphae, branched and intertwined (typical of molds)
Yeast
Non-filamentous, unicellular fungi
Fission yeasts
divide symmetrically
Budding yeasts
divide asymmetrically
Dimorphic Fungi
Yeastlike at 37°C and moldlike at 25°C
Pseudohyphae
Buds that do not separate from the mother cell
Fungi Reproduction
Sexual (main method) and asexual through the formation of spores
Asexual spores
Formed by the hyphae, and become genetically identical to the parent after germination
Sexual spores
Fusion of nuclei from two opposite mating strains
Two types of asexual spores
Conidiospore
Sproangiospore
Conidiospore (conidia)
Not enclosed in a sac, produced in a chain at the end of a conidiophore
3 types of Conidia
Arthroconidia
Blastoconidia
Chlamydoconidia
Arthroconidia
formed by the fragmentation of a septate hypha into single thickened cells
Blastoconidia
buds come off of the parent cell
Chlamydoconidium
Thick-walled spore formed by rounding and enlargement within hyphae
Sporangiospore
Formed withing sporangium (sac), at the end of an areal hypha (a sporangiophore)
3 Phases of Sexual Reproduction
Plasmogamy
Karyogamy
Meiosis
Plasogamy
Haploid nucleus of donor cell (+) penetrates recipient's cytoplasm (-)
Karyogamy
(+) and (-) nuclei fuse to form diploid zygote nucleus
Meiosis
Diploid nucleus --> Haploid nuclei
Fungi Adaptations
-Grow in acidic, dryer, aerobic environments
-metabolize complex carbohydrates
Sexual Spores
-Zygospore
-Ascospore
-Basidiospore
Ascospore
formed in a sac
Zygospore
spore in a thick wall, formed by fusion of haploid cells
Basidiospore
Formed on a pedestal
Rhizopus Life Cycle
Zygomycete
Talaromyces Life Cycle
Ascomycete
Life Cycle Basidiomycete
Basidiomycete
Teleomorphic Fungi
Produce sexual and asexual spores
Anamorphic Fungi
Produce asexual spores only
