Macromorphology (smell):
Geotrichum candidum 
The colonies are white and have a fuzzy appearance both on agar plates and when the fungus grows on cheese.

Taxonomy/phylogeny:
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.
