It’s a real nice specimen. I’ll send it for inclusion in the NJ collection if desired. Also, I’ve got a spore print, so I can test for amyloidity just to be sure it’s not a flavoconia.

No vouchers from NJ

This is according to Rod’s website. I have to ask John B. if this amanita is on the NJMA species list.

Not common.

The few times I have found frostiana, it has been near oak.

How common is it…

…in your neck of the woods? I am yet to find this one in NJ.
