[1] The species was established when the genomes of the four former varieties of Aureobasidium pullulans were sequenced and the large differences between them were discovered.

Colonies on malt extract agar on average grow to 25 mm in 7 days (at 25 °C), appearing smooth and shiny due to the leathery structure.

[1] The genome of A. namibiae (as well as other closely related species) contains unusually high numbers of genes for extracellular enzymes for carbohydrate degradation (CAZy) and proteases, MFS membrane sugar transporters, and alkali metal cation transporters (or ion transporters).

Genes presumably involved in the synthesis of the biotechnologically important polysaccharide pullulan and siderophores were found, but the gene for antibiotic Aureobasidin A could not be identified.

Genes possibly associated with the degradation of plastic and aromatic compounds are also present.
