Yeasts
- Unicellular
- Macroscopic; Pasty colonies that resemble bacteria
- Microscopic; Oval/Round that produce budding
- In tissue appear pseudohyphae
  - chain of easily disrupted fungal cells that is intermediate between a chain of budding cells and a true hypha, marked by constrictions rather than septa at the junctions.
Mould
- Multicellular
- Macroscopic; Pigmentation seen on reverse and surface texture is variable.
- Microscopic; Hyphae with spores
- Mould Definition
  - Masses of Filaments called Hyphae
  - Multicellular Filamentour; network of hyphae
