Abstract

Three taxa of the genus Amanita section Phalloideae with white basidiocarps are described and illustrated. They are A. exitialis, A. oberwinklerana and A. subjunquillea var. alba. The first species is new to science, while the second is new for China. Known distribution range of the third taxon in China is widely extended. Amanita exitialis is lethal, while the other two taxa are supposed to be also very poisonous. The holotype of A. exitialis is deposited in the Mycological Herbarium of Guangdong Institute of Microbiology (HMIGD).
