The Genus Amanita produces some of the most beautiful fruit bodies in the Fungi Kingdom, I wish I could make it to your fungus fair, at least I can see the collections here!

not tall so much as fat…

they can get quite ponderous for an amanita.

some are also quite delicate and slender.

Nice find Debbie,
