It certainly seems to fit the concept of the species as treated in Yang’s 1997 thesis (which is in German, in case you can read that language).

Rod, I just went by sight. The other species that you suggested didn’t look like what I saw today. There were literally hundreds on the hills today. I didn’t see any major appearance changes with age. Since I saw how vast the fruiting was, I assumed the websites I used for reference would list it as one of the most common species to fruit in Japan.

How did you come to choose the name “pseudoporphyria”?

Did you use Japanese literature? Which book(s)?

New photos of stem base seem to confirm Amanita.

Thanks guys for your wonderful comments, and, in essence, free education (-_-)! I thought about combining the three mystery Amanita observations, but then I will lose the precious comments.

Inclined to agree…

The virgate, cap with pallid spots does indeed suggest 11253 and 11256.

Did you mean obs. 11253 and 11256? Yes, it could well be.

This looks like an older version of same green Japanese amanita…

Skirt-like ring on upper stem and free, white gills suggests Amanita or Lepiota. Need to see stem base.

Cap appearance more consistent with Amanita.
