Amanita hemibapha

Amanita hemibapha, commonly known as the half-dyed slender Caesar, is a species of agaric found in southeast Asia and Oceania, although some distribution reports may refer to different taxa.
The variant "Amanita hemibapha var. ochracea" found in China have been reported to cause dizziness and nausea after eaten in large quantity, thus consumption is recommended against. The species is also noted to be confusable with the lethally toxic "Amanita subjunquillea".
