Amanita neoovoidea (genus Amanita Pers.) poisoning leads to acute renal failure. Here, we present seven case reports of acute renal failure with acute hepatic failure due to ingestion of A. neoovoidea. Clinical manifestations included gastrointestinal symptoms 1–72 h after ingestion; elevation of renal parameters and blood uric acid, blood urea nitrogen, and creatinine levels; a few abnormal hepatic parameters, primarily albumin decrease and alanine aminotransferase increase; and elevation of zymogram parameters such as cholinesterase and lactate dehydrogenase. To determine whether the hepatic/renal lesions were caused by amanitins, we analyzed the blood and urine samples of patients and specimens of poisonous mushrooms. Morphological and molecular biological analyses indicated that the mushroom was A. neoovoidea. However, no amatoxins and phallotoxins were detected in its basidiomata. • Seven people were poisoned after ingesting some white wild mushrooms in 2016 in Anhui province. • Morphological analysis identified the specimens as A. neoovoidea. • The specimens were identified as A. neoovoidea by molecular biological method.
