Thanks for the information, the Amanita appears on my friends property, outside his front door and chances of seeing it again are quite likely.

I think this is the species (or one of the species) that is called A. nauseosa

in eastern Australia. It is probably not mycorrhizal. If I am correct, it is in Bas’ stirps Nauseosa. It is very similar to the species I referred to A. manicata in Hawaii (probably not native there).

Images of Hawaiian material are on the WAO website here:


Notice that the present images and the Hawaiian images lack the “bundle of fur” around the stem under the partial veil. That bundle of fur is diagnostic (so far as is known) for the true manicata.

I suggest that a name that might be used here would be “A. nauseosa sensu auct. Australia”. Considering the number of species that seem to have been exported from Australia to Hawaii, it is plausible that the present species was moved with soil along that route.

Dried material of this species from Australia would be of great interest to me. It would help clarify its distinctness from manicata.

Very best,
