As you know by now, this material belongs with material collected in Texas by David Lewis under the temporary code “sp-T31.” Again, thank you for being generous with collections and your time.

Very best,


Thank you, Patrick.

Your specimen provided a surprise under the microscope. When you dried it, it was producing some giant spores with about double the volume of normal spores…indicating that some basidia were 2-sterigmate. Early in sporulation, a number of amanitas pull this trick. You’re material, image, and the spore data have all been merged into the techtab at

So, yes, as long as you attribute it and let people download and use it. So if you do something silly like use a javascript to try to block right click save as you might be violating the license. :)

Thank you, Patrick

Thank you.

The package containing the voucher for these photographs arrived in the mail yesterday. May I use the bottom photo at about 600 dpi tall on the new Amanitaceae site?

Very best,


Wish we got these up north.
