Amanita hemibapha, Amanita javanica, Amanita caesareoides (which is called “hemibapha” in Japan) all belong in stirps Hemibapha of Amanita sect. Caesareae. They have a big, white, membranous, thick saccate volva at the stipe base. This material doesn’t have that feature. Amanita rufoferruginea (to which this material appears to belong) is a species of sect. Amanita.

is the real name. MO wouldn’t let me put this. It’s a Hongo discovery.

Please take a look at the reference if you are interested. I always thought the Fer. name didn’t quite fit on a macro level even. I saw this today and it must be what I found. It actually looks the same.

love the rust-orange, powdery universal veil…apparent on your hands, if not the mushroom.
