Yeast: The Unicellular Fungal Form
Captions available
The idea
A yeast is a unicellular fungus reproducing by budding or fission rather than hyphal growth; some species switch between yeast and hyphal forms.
In practice
Saccharomyces cerevisiae grows as budding yeast cells, while a dimorphic fungus like Candida can shift to a hyphal form.
Where people slip
"Yeast" names a growth form, not one taxonomic group — unicellular forms appear scattered across multiple fungal phyla.
