A novel species, Aspergillus uvarum sp. nov., is described within Aspergillus section Nigri. This species can be distinguished from other black aspergilli based on internal transcribed spacers (ITS), β-tubulin and calmodulin gene sequences, by AFLP analysis and by extrolite profiles. Aspergillus uvarum sp. nov. isolates produced secalonic acid, common to other Aspergillus japonicus-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 Aspergillus aculeatus, 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 Aspergillus uvarum sp. nov. is IMI 388523^T=CBS 127591^T=ITEM 4834^T=IBT26606^T.

The GenBank/EMBL/DDBJ accession numbers for the β-tubulin, ITS and calmodulin gene sequences of the strains examined in this study are shown in Table 1. The MycoBank accession number for Aspergillus uvarum sp. nov. is MB 510962 (http://www.mycobank.org).

Phylogenetic trees based on ITS and calmodulin gene sequence data and a dendrogram based on cluster analysis of AFLP data are available with the online version of this paper.
