mycete=

suffix indicating a fungus

What does mycosis(s)/mycoses(p) mean?

Hyphae:

long branching filamentous structure of a fungus

What is the main mode of vegetative growth in fungi?

hyphae

Aerial hyphae are found:

above ground (contact with air)

underground

Mycelium=

collectively to the hyphae that form a fungal colony

What are the two major classes of hyphae?

septate and non-septate

What is a septum in fungi?

a partition dividing filamentous hyphae into discrete cells in fungi

Fungi phyla are dictated by:

sexual spores

What are the 4 main fungi phylas?

-ascomycetes

-basidiomycetes

-deuteromycetes

Ascomycetes are a ____ fungi

sac

Basidiomycetes is a ___ fungi

club

imperfect; they do not make sexual spores

For zygomycetes, whar are asexual spores called and where are they found? Sexual spores? What kind of hyphae do they have?

-asexual= sporangiospores produced in sporangium

-sexual= zygospores produced in zygosporangium

-hyphae= aseptate (no septum)

For ascomycetes, what are asexual spores called and where are they found? Sexual spores? What kind of hyphae do they have?

-asexual= condidospores produced in the conidiosphores

-sexual= ascospore produced in the ascus

-hyphae= septate
