Deadly poisonous amanitae are common and widely distributed in China.They cause dramatic poisonings or even deaths every year.The well-known lethal mushrooms Amanita phalloides,A.verna and A.virosa,all originally described from Europe,were repeatedly reported from China,but no reliable record can be confirmed.However,other lethal mushrooms,i.e.A. exitialis,A.fuliginea,A.oberwinklerana,A.subjunquillea var.subjunquillea,and A.subjunquillea var.alba can frequently be found in various forests in China.Amanita fuliginea may easily be confused with A.manginiana sensu Chiu and A.yuaniana,both of which are favorable wild edible mushrooms in southwestern China.Moreover,the edible mushroom A.chepangiana may be mixed up with A.exitialis,A.oberwinklerana,and A.subjunquillea var.alba.A key to the Chinese taxa of Amanita mentioned above is provided.
