Poisoning Case of Chlorophyllum cf. molybdites in Indonesia

Wild edible mushrooms are one the germplasms which consumed by some people in Indonesia. However, due to the similar morpholgical appearance from one mushroom to another, cases of wild mushroom poisoning might be occurred as the result of the misidentification at foraging time. One of the common poisonous mushrooms which easily found around residence area is Chlorophyllum molybdites. To date, there is no database of mushroom poisoning cases in Indonesia. The aims of this research was to provide the information regarding C. molybdites poisoning cases in Indonesia. This is a literature-based quantitative research. During the last 10 years, it is suspected that there have been 4 cases of Chlorophyllum cf. molybdites poisoning in Indonesia with a total of 34 victims and none has died. This mushroom is known to contain toxic compounds, namely polymeric protein. The main constraint related to determining the taxonomic identity of poisonous mushroom, is the lack of information and documentation of samples that cause poisoning in Indonesia. This research explained how to recognize the character of C. molybdites, information on its distribution, and its toxicity aspects. With the complete information as a medium for disseminating mycology knowledge, it is hoped that cases of wild mushroom poisoning can be prevented in the future in Indonesia.
