The yeasts range from 3µm to 5µm and are oval or spherical cells. '''Pseudohyphae''' are produced by some yeasts which are chains of irregular yeast cells. '''Dimorphic fungi''' change from the mycelial form into yeasts in certain conditions, e.g. 37°C or when inside animal tissue. | The yeasts range from 3µm to 5µm and are oval or spherical cells.
