Aspergillus versicolor is found globally including in the arctic regions. A. versicolor is remarkable for the wide range of mycelial and reverse pigmentation it can produce, especially if cultures are incubated for 14 days or longer. It so far has no known sexual form, although other members of the section Nidulantes form Emericella teleomorphs. A. versicolor is capable of growing at very high salinity conditions and has been found in the arctic regions as well as on the Mir space station. The Dead Sea is amongst the most arduous environments on earth, with 340 g/L total dissolved salts. Not only has A. versicolor been isolated from the Dead Sea water, but it remains viable for up to 8 weeks in laboratory conditions. Comparison of A. niger, A. nidulans and A. oryzae demonstrated significant differences in presence of biomass-degrading enzymes and utilisation of carbon sources. As A. nidulans is phylogenetically distant from the other sequenced aspergilli adding A. versicolor will enable a better analysis of the apparently unique features of A. nidulans and the section Nidulantes, thereby strengthening overall comparative genomics. A. versicolor is also the species of choice for comparison by most A. nidulans research groups.
