By comparing this phylogenetic tree with the classification systems of Bas (1969) and Singer (1986) which are based on morphological characters and have been widely accepted, we examined the phylogeny of Japanese Amanita species. Our results supported the taxonomical treatment in subgenus level of Bas (1969) and Singer (1986) who divided the genus Amanita into two subgenera Amanita and Lepidella based on the amyloidity of spores. However, in section level, we suggested that subgenus Amanita should be divided into three sections (Amanita, Vaginatae and Caesareae). Moreover, our results showed the necessity to rearrange the disordered assemblage of members in the subgenus Lepidella. As for three subspecies of A. hemibapha and three varieties of A. vaginata, it is necessary to grade up their taxonomical ranks from subspecies / variety to species. It appeares that A. pantherina and A. muscaria are extremely related phylogenetically. The molecular biological technique was proven to be sensitive for detecting taxa that are difficult to detect by morphological characters.} }
