Amanita fuliginea, commonly known as the east Asian brown death cap, is a species of deadly poisonous mushroom in the family Amanitaceae. It was described as new to science by Japanese mycologist Tsuguo Hongo in 1953.[1] Fruit bodies have convex, dark gray to blackish caps measuring 3–6 cm (1.2–2.4 in) in diameter. The gills, largely free from attachment to the stipe, are white and have short gills (lamellulae) interspersed. The spores are roughly spherical, amyloid, and typically measure 8–11 by 7–9.5 µm. The mushroom is common in China, where it has caused poisonings,[2] a review of cases in southern China finding it had been responsible for the poisoning of 352 people, 79 of which died, between 1994 and 2012.[3]
Several toxic peptides have been identified from the mushroom: α-amanitin, β-amanitin, amaninamide, phallacin, phallacidin, phallisacin, desoxoviroidin, and an additional unidentified phallotoxin.[4] A. fuliginea is classified in Amanita section Phalloideae, which contains several deadly toxic species.
