I always ask for a portion because a collector might wish to keep part for future examination him/herself.

We’ll appreciate what you’d like to send.

Yes, I can send the whole thing if you like.

May we have a part of the specimen?

I see on the WAO website that we have no data on material from Georgia.

It would be quite sufficient to have a longitudinally divided half of the basidiome.

Very best,

Rod

No I did not get to see it descend in “two stages” it was put up to dry asap.

Did you get to see the annulus appearing to descend in “two stages”? [edited]

I wish I had a microscope so I could look at the spores.

The annulus is attached at the top of the stem, and there’s a faint aroma of apples. You are correct Rod, thanks.

This is a first for me, always nice to find a new Amanita.

See…

Did you notice an odor? [edited]

The shape of the bulb, the radially oriented hair-like radial lines on the cap (“virgate” pigmentation), the non-striate cap margin, and the gray to brown tint of the cap pigment, suggest A. submaculata, which has range that appears to run from New England to east Texas often in mixed forests (usually with at least oak and/or pine). We have it in the NJ Pine Barrens. It appears to have a range of odors from apple to something a bit like anise or (once) a new automobile tire…usually fruity. The annulus should be rather large and attached at the top of the stem. Usually, the outer half of the annulus detaches from the gills first and you get a fold around the middle of the annulus so when it is freshly, fully [edit] detached it is like an early 18th Century ball gown spreading outward and then at a steeper angle downward.

The spores would be amyloid, and placement would be in sect. Validae. Can you confirm any of the characters that we can’t see in the photograph?

R.
