Fungi exist in many environments, in air, bathrooms of houses, on wet floors, grounds, showers, dirty, and wet laundry, air conditioners, and humidifiers, garbage bins, dish racks, carpets, in dark, and humid environments as cellars, and attics. Forensic mycology is a branch of science which describes species of fungi. In the past, forensic mycology was mostly restricted to the examination of poisonous, and psychotropic species, in recent years it starts to play a role in the determination of the time of death, burial place, and time of leaving the body where it was found, and cause of death (hallucination, and poisoning). Forensic mycology is considered as an auxiliary method in the determination of the time of death just like forensic entomology. In our study, by presenting a case whose dead body was covered with fungal plaques during postmortem period, we aim to review literature concerning fungal growth on corpses.
