About Amanita pseudoporphyria Hongo
Amanita pseudoporphyria Hongo, commonly called Hongo's false death cap, is an agaric fungus species belonging to the Amanitaceae family. This species is quite common in southern China, and has also been recorded in North India, Thailand, and Nepal. It grows either solitarily or gregariously in coniferous forests. This mushroom is poisonous. In 2000, a 66-year-old man with diabetes developed delayed onset acute kidney injury after eating this mushroom. The intoxication symptoms he experienced were similar to those caused by poisoning from the North American species Amanita smithiana and the Mediterranean species Amanita proxima. A kidney biopsy taken from the patient showed acute tubular necrosis with only minor glomerular abnormalities. The patient received treatment that included a three-week course of haemodialysis, and fully recovered from the acute kidney failure two months after ingestion. Wang et al. (2004) and Yang (of unknown publication date) reported that this mushroom is sold in free markets in Yunnan, China, mixed in with the species Amanita caojizong.
