Didn’t look as intently as I prob. could have. Thanks Again Rod!

I think it would be worth considering A. porphyria as a possible determination….

especially since the partial veil looks as though it may be becoming gray in at least one picture.

It looks like there is a bulb at the stipe base rather than a volval sac surrounding a bulb-less stem.

In the Americas, there is no known species of section Vaginatae with a ring on the stem.

Very best,

Rod Tulloss
