Abstract

Two isolates belonging to Aspergillus section Fumigati were recovered from German soil on itraconazole containing agar media. Phylogenetic analysis and phenotypic characterization of both isolates show that they represent a novel species named Aspergillus oerlinghausenensis (holotype CBS H-22119(HT), ex-type CBS 139183(T) = IBT 33878 = DTO 316-A3). The species is phylogenetically related to A. fischeri and A. fumigatus. Aspergillus oerlinghausenensis can be differentiated from A. fischeri by its higher growth rate at 50°C. Furthermore, A. oerlinghausenensis is protoheterothallic as only the MAT1-1 idiomorph was detected, while A. fischeri is homothallic. The species differs from A. fumigatus by a weak sporulation on malt extract agar at 25°C, a floccose colony texture on Czapek yeast extract agar and malt extract agar and subglobose instead of subclavate vesicles. The cyp51A promoter region of A. oerlinghausenensis deviates from the previously reported cyp51A promoter regions in A. fumigatus and potentially presents a novel azole resistance conferring modification. Due to the close relationship of A. oerlinghausenensis with A. fischeri and A. fumigatus, this species is placed in a good position for comparative studies involving these species.
