Regarding the ring, I’m inclined to agree.

Amanita peckiana has a true annulus that is visible briefly as the button is expanding, but eventually disappears. This is the only membranous partial veil of which I know in section Amidella.

Did you see that Stephen Russell (MO #111311) has brought up one of my old numbers that was not posted on the WAO site? Its posting there is underway now:

the well-formed ring on the stipe is an anomaly. I have found amidellas with scaly-fluccose ring zones. But I don’t recall seeing such a nice annulus on any of these.

I have also experienced the phenomenon of an amanita growing after having harvested it.

The stain on the cap

did not appear to darken further. Interestingly, the mushroom grew in size while being stored in a paper bad for a few hours. The cap expanded and the volval sack shrank in size (see pic #44 for comparison).

Has the stain on the cap darkened further?
