The study was conducted on a child's mummy aged 6 to 8 years, with a damaged skull. It was found in Dahshur, Egypt. 10 fungal species were isolated and identified. Fungi have been determined by PCR amplification and sequencing as follows: Cladosporium cladosporioides (LC325159), Penicillium chrysogenum (LC325162) and Aspergillus flavus (LC325160). Modern linen samples were inoculated and incubated by the isolated fungi for a period of three months. Fungi decay results were assessed using Energy Dispersive X-Ray Spectrometry (EDX) and X Ray Diffraction (XRD). It was evident that NaCl (100%) have been used in the mummification process and the three identified fungi could grow on linen even under high saline (NaCl) conditions. C. cladosporioides showed a considerable increment in hyphal production, while P. chrysogenum hyphae were filled with salt crystals. Growth of A. flavus covered linen surface, while salt crystals were found in the conidiophores. Xerophilic and Halophilic fungi grown and caused decay of the mummy located in the burial chamber.
