Technical Abstract: ß-tubulin, calmodulin, internal transcribed spacer and partial lsu-rDNA, RNA polymerase, DNA replication licensing factor Mcm7, and pre-rRNA processing protein Tsr1 were amplified and sequenced from 62 A. versicolor clade isolates and analyzed phylogenetically using the concordance model to establish species boundaries. We used phylogeny to define species and phenotype from 10d Czapek yeast extract (CYA) cultures to describe the species. Aspergillus austroafricanus, A. creber, A. cvjetkovicii, A. fructus, A. jensenii, A. puulaauensis, A. subversicolor, A. tennesseensis and A. venenatus are described as new species and A. amoenus, A. protuberus, A. tabacinus and A. versicolor are accepted as distinct species on the basis of molecular and phenotypic differences. polymerase chain reaction (PCR) primer pairs used to detect A. versicolor in sick building syndrome studies have a positive reaction for all of the newly described species.
