Aspergillus section Aspergillus (Gams et al. 1985; A. glaucus species group according to Raper and Fennell 1965) includes species with uniseriate, blue-green conidial heads and smooth-walled, yellow cleistothecia typically entangled by aerial hyphae encrusted with yellow, orange or orange-red granules. Members of section Aspergillus are generally xerophilic, requiring high concentrations of sugar or salt for optimal growth, and are widely distributed in nature. The growth attributes in combination with their ascospores that are able to survive at high temperatures, help explain why most species in this section are food and feed contaminants (Spittstoesser et al. 1989; Gock et al. 2003; Butinar et al. 2005; Samson and Varga 2010). Many species in section Aspergillus are also mycotoxin producers that may be harmful to animals and humans (Buchi et al. 1971; Nazar et al. 1987; Vesonder et al. 1988; Eicher and Ludwig 2002; Yildiz and Coksö yer 2002). The connection between the teleomorph genus Eurotium Link and Aspergillus P. Micheli ex Haller was primarily established by De Bary (1854). While Raper and Fennell (1965) maintained the teleomorphic species belonging to A. glaucus group in the anamorphic genus Aspergillus, Malloch and Cain (1972a, b) placed them under the teleomorphic genus Eurotium in the family Trichocomaceae. It was only Blaser (1976) who firmly established the connection of Aspergillus glaucus with Eurotium herbariorum (Weber ex FH Wigg.) Link by neotypification. However, in the last revision of the family
