Starmerella

Starmerella is a genus of fungi within the Saccharomycetales order. The relationship of this taxon to other taxa within the order is unknown ("incertae sedis"), and it has not yet been placed with certainty into any family. 
Several members of the "Starmerella" clade are associated with flowers and flower-visiting insects like bees and bumblebees; these yeasts cope well with high sugar niches. Many strains (species) of the "Starmerella" clade, including "Starmerella bombicola" and "Candida apicola" are known to produce sophorolipids which are carbohydrate-based, amphiphilic biosurfactants.
