ABSTRACT: It is widely known that the genus Amanita includes various taxa: edible and inedible, dangerous and sometimes even deadly species. Despite the number of studies carried out on this genus, the toxicity of some species, such as the group of white fungi, remains dubious. Hence Amanita ovoidea (Bull.) Link. is considered as edible and even tasty both popularly and in some scientific publications, and as poisonous in others, having caused various cases of poisoning. This study stems from a case of poisoning by A. ovoidea in Siena (Italy). Tests were performed with the aim of finding a scientific answer regarding the real edibility or inedibility of A. ovoidea. Analyses included phytochemical screening, toxicological tests on human ex vivo peripheral blood mononuclear cells, and measurements of soil and mushroom pollution by heavy metals.
