Two novel species of Aspergillus section Nigri from Thai coffee beans are described as Aspergillus aculeatinus sp. nov. and Aspergillus sclerotiicarbonarius sp. nov. Their taxonomic status was determined using a polyphasic taxonomic approach with phenotypic (morphology and extrolite profiles) and molecular (β-tubulin, internal transcribed spacer and calmodulin gene sequences) characteristics. A. aculeatinus sp. nov. is a uniseriate species with a similar morphology to Aspergillus aculeatus and Aspergillus japonicus, but producing smaller conidia (2–5 µm). A. aculeatinus sp. nov. produced neoxaline, secalonic acid D and F, and aculeacins. A. sclerotiicarbonarius sp. nov. is a biseriate species similar to Aspergillus carbonarius and Aspergillus ibericus, but produces abundant sclerotia and some unique indol-alkaloids. The type strain of Aspergillus sclerotiicarbonarius sp. nov. is CBS 121057T (=IBT 28362T) and the type strain of Aspergillus aculeatinus sp. nov. is CBS 121060T (=IBT 29077T).

Abbreviations: ITS, internal transcribed spacer region of the rRNA gene cluster; NJ, neighbour-joining; SEM, scanning electron microscopy

The GenBank/EMBL/DDBJ accession numbers for the β-tubulin, ITS and calmodulin gene sequences of strains examined in this study are shown in Fig. 1 and Supplementary Figs S1 and S2 (available with the online version of this paper).

The Mycobank (http://www.mycobank.org) accession numbers for A. sclerotiicarbonarius sp. nov. and A. aculeatinus sp. nov. are MB 504407 and MB 505075, respectively.

Neighbour-joining phylogenetic trees based on β-tubulin and ITS gene sequences are available as supplementary figures with the online version of this paper.
