The rings are the remnants of the part of the universal veil that is…

between the developing stem and the developing gills in the button stage of the Amanita. You usually only see one ring, but two or more happens (obviously). The volval material of this group often changes color after exposure to air. In the European __ceciliae_, A. sororcula from Colombia and Mesoamerica, the eastern North American species to which Dave pointed, the ring(s) can become very dark after drying. I got into the habit of sorting dried Andean oak forest material on the basis of the black ring…such specimens were always sororcula. We don’t know how many such taxa are in eastern North America…yet, but we have an idea that there are more than one.

I agree, ret. The rings on the stipe caught me off gaurd and lead me to consider it as a possible spieces of Amanita. Unfortunatley I did not have a camera handy after the initial picking. I am very new to this obsession and really appreciate everyones help and patience! Thanks!

Or something very, very close.

Maybe we ought to take notes on the appearance of old shriveling caps… I wonder if features like color are constant in such things?


Looks like this may be an old dried up…
