Definition of Terms Flashcards
Asexual form of a fungus
Anamorph
Specialized conidiogenous cell from which a
succession of spores is produced and has a
column of apical scars at its tip.
Annellide
Ability to use a specific carbon/nitrogen source
for growth.
Assimilation
Without cross-walls or septa.
Aseptate
Process of conidium formation
Conidiogenesis
Existing hyphal cell is converted to
conidia (segmentation)
Thallic
Conidia produced because of budding
Blastic
Asexual propagule formed on the side/end of
the hypha/conidiophore. It may consist of one
or more cells. Always borne externally.
Conidium
Small, singled cell conidia
Microconidia
Larger, segmented into 2+ cells
Macroconidia
Darkly pigmented
Dematiaceous
Ability to use a specific carbohydrate in the
presence of other organic compounds,
resulting in gas production.
Fermentation
Colonies with a cotton-like texture.
Floccose
Spores with a spindle-like shape.
Fusiform
Colonies with wax-like texture.
Glabrous
Self-sterile, sexual reproduction can’t be done
unless 2 compatible mating strains are present.
Heterothallic
Self-compatible, sexual reproduction can take
place within an individual strain.
Homothallic
Colorless, transparent, translucent.
Hyaline
One of the individual filaments making up the
mycelium.
Hypha (pl.hyphae)
Filamentous fungus
Mold
Hyaline/lightly colored.
Moniliaceous
Mass of branching filaments making up the
vegetative growth of a fungus.
Mycelium
Cell with several nuclei.
Oligokaryotic
Having a few septa.
Pauciseptate
Chain of yeasts that resulted from budding and
have elongated w/o detaching from each other,
forming a hypha-like filament.
Pseudohypha
Short branching hypha resembling a root.
Rhizoid
Having cross-walls or septa.
Septate
Monophyletic clade of species with equivalent
clinical relevance.
Species complex
Specialized hypha that develops a sporangium.
Sporangiophore
Development of a single conidium at
successive sites along a lengthening
conidiogenous cell.
Sympodial
Sexual form of a fungus.
Teleomorph
Vegetative growth of a fungus.
Thallus
Unicellular, budding fungus.
Yeast
