I also found more A. calyptratoides recently in a different location in the same park too in case you missed the post on MO. I suppose these are more typical looking of that species.

I’m habitually saving unusual (at least to me) Amanita’s now and happy to send it to you for your examination. It’ll be in the mail early next week.

Happy New Year to you too:)

The attached gills with decurrent “teeth” on the upper stipe are not unknown….

…for Amanita. Also the thin calyptra on the cap is very interesting to see.

Happy New Year.

Very best,


That is a cool looking critter.

Do you have some dried material of it that you could spare. I am curious.
