Abstract

A novel species, sp. nov., is described within section . This species can be distinguished from other black aspergilli based on internal transcribed spacers (ITS), -tubulin and calmodulin gene sequences, by AFLP analysis and by extrolite profiles. sp. nov. isolates produced secalonic acid, common to other -related taxa, and geodin, erdin and dihydrogeodin, which are not produced by any other black aspergilli. None of the isolates were found to produce ochratoxin A. The novel species is most closely related to two atypical strains of , CBS 114.80 and CBS 620.78, and was isolated from grape berries in Portugal, Italy, France, Israel, Greece and Spain. The type strain of sp. nov. is IMI 388523=CBS 127591=ITEM 4834=IBT26606.
