Macromorphology (smell):
 | The colonies are white and have a fuzzy appearance both on agar plates and when the fungus grows on cheese. |
|---|
Micromorphology:
  | Forms rectangular arthroconidia, the size of which is 5-12 x 2.5 µm. Some strains grow like yeast, while others may have a more moldy appearance. |

| Disease/effect:
| The fungus is considered to belong to the normal flora in the mouth and intestines in animals and humans, but can sometimes cause infections.
| Hosts/substrate | Disease/effect | Clinical picture or result |
|---|
| Dogs | Geotrichosis | May in rare cases cause disseminated infection. | | Fruits and vegetables | Sour rot | Yellow-brown or purple coating on the affected substrate. | | Humans | Geotrichosis | Can affect individuals with a weakened immune system and cause infection in the respiratory tract, mouth, skin and vagina. |

| Practical use: | G. candidum is used in the production of certain milk products such as cheeses (camembert, saint-nectaire reblochon etc.) and yogurt (viili). This fungus also has an antagonistic effect on certain pathogenic bacteria such as e.g. Listeria monocytogenes.
It has been found that G. candidum can break down polycarbonates in e.g. CDs. |
