A novel species of the black yeast genus Exophiala (order Chaetothyriales) is described.
Strains were repeatedly obtained by enriching samples of wild berries from different
plants, guano-rich soil and from oak railway ties treated with arsenic creosote under
a toluene-rich atmosphere. An identical strain was encountered in a closed arsenic mine
polluted by alkyl benzenes. Its potential use for purposes of bioremediation is discussed.
