Notes: There were alot of these growing next to the concrete trail and steps. It was not growing from the concrete. I simply moved it to avoid mosquitos. My naming is based on information from http://www.ne.jp/asahi/mushroom/tokyo/index.htm, where the name Mairei is used.

Here are two more alternatives…

There is another set of alternatives to add to the possibility of a species in the “pantherina-group.” The two species A. subglobosa Zhu L. Yang and A. ibotengutake Oda et al., which are very, very similar and may be synonymous look like a species of the afore-mentioned group, but are actually have a common ancestor with the “A. muscaria-group.” Since these two taxa are east Asian (A. pantherina also is reported to occur in Japan), they should be considered. With no dried specimen, I don’t think that a difference between subglobosa and ibotengutake can be established from a photograph.

Amanita mairei is restricted to the Mediterranean region, as far as is known…

Amanita mairei was originally described from North Africa and is presently known only from the Mediterranean region. It is a species of Amanita sect. Vaginatae. The present species is superficially similar to Amanita pantherina, although it does not seem to be that species to me.

I would suggest going back to the site you used and looking at the images under “section Amanita”. It seems to me you may find some possibilities depicted there.
