aspergillus and zygomycetes Flashcards
aspergillus are
hyaline molds
maturation time of aspergillus molds
3-5 days
golden granular surface
white apron
small and spherical conidia that extend all the way around phialides
“sunburst”
vesicles are large and spherical and give rise to a double row of cells
flavus
green granular and rugose with a white apron
conidia extend in lines out from phialides
single row phialides
round and not densely covered vesicles
“paintbrush”
fumigatus
3 days to mature
black and peppery with a cream reverse
rough jet black conidia
thick phialides
spherical vesicles often completely concealed
niger
outer cinnamon brown apron with a dark brown center
double row of conidia
thickly covered phialides
dome shaped and densely covered vesicles
“back-scratcher”
terreus
produce sexual cells
rapid growers 3 days
growth extends to border of petri dish
wooly texture
reverse is light colored
zygomycyetes
border to border fluffy white colony
inter-nodal rhizoids
rounded spores that come off paired sporangiophores
funnel like flare of vesicle/phialide
hyaline aseptate hyphae
lichtheimia
small and spherical spores within a round capsule
like gumballs in a gumball machine
sporangiophore is curved backward
cincirella
echinate sporangioles with denticles
sporangiophores terminate in a columella with bulbous balloon-like spores 2-5 coming off rounded end
cunninghammella
white and wooly to buff brown
no rhizoids
lots of spores inside a bulbous columella
toadstool shaped columella
mucor
root like rhizoids
nodal derivation of sporangiophore with an umbrella shaped columella
think delicate mushrooms
rhizopus
may make rudimentary rhizoids
spores are in lines extending from columella
“daisy head”
spherical columella
club shaped conidiophore
broad and aseptate hyphae
syncephalastrum
