The very first one states the mushroom was misidentified.

I'll assume from there you failed to read any of it.

Edit:

lol, here's the paper he cited and deleted:

The 4th one is the one you already admitted had bad data.

At least one of the other two clearly states that the mushroom was unidentified. You will have to read or delete both.
