Abstract
On the basis of molecular phylogeny, it is clear that the fungi treated as Amanita pantherina in Japan are confused, i.e., A. pantherina and a misidentified species. As for morphology, the misidentified species differs from A. pantherina by having clamp connections on hyphae and basidia, a larger-sized fruitbody, ascending volval rings of stipe base and deciduous annulus. It is clear that the misidentified species is a poisonous fungus containing ibotenic acid and muscimol and causes the Pantherina syndrome. On these characters, it is concluded that the misidentified species is the unexplored Amanita species treated under the Japanese name ‘ibotengutake’ after which ibotenic acid was named. Here, we described it as a new species Amanita ibotengutake.
