A worldwide survey of  Wallemia  occurring in house dust and indoor air was conducted. The isolated strains were identified as  W .  sebi  and  W .  muriae . Previous studies suggested that the  W .  sebi  phylogenetic clade contained cryptic species but conclusive evidence was lacking because only the internal transcribed spacer (ITS) marker was analyzed. The ITS and four protein-coding genes ( MCM 7,  RPB 1,  RPB 2, and  TSR 1) were sequenced for 85 isolates. Based on an initial neighbor joining analysis of the concatenated genes,  W .  muriae  remained monophyletic but four clades were found in  W .  sebi , which we designated as  W .  sebi  clades 1, 2, 3, and 4. We hypothesized that these clades represent distinct phylogenetic species within the  Wallemia sebi  species complex (WSSC). We then conducted multiple phylogenetic analyses and demonstrated genealogical concordance, which supports the existence of four phylogenetic species within the WSSC. Geographically,  W .  muriae  was only found in Europe,  W .  sebi  clade 3 was only found in Canada,  W .  sebi  clade 4 was found in subtropical regions, while  W .  sebi  clade 1 and 2 were found worldwide. Haplotype analysis showed that  W .  sebi  clades 1 and 2 had multiple haplotypes while  W .  sebi  clades 3 and 4 had one haplotype and may have been under sampled. We describe  W .  sebi  clades 2, 3, and 4 as new species in a companion study.
