slow process, much slower than, say, the raspberry reaction to damage in Amanita mutabilis.

If you see this little lady again, I’d be very interested in seeing dried material.

Thank you for your kind words about the websites. Comments are much appreciated.

Very best,


Thanks for commenting.

The margin was indeed striate, around 15 to 20% of the cap diameter. I do print and dry some finds, but sadly not this one. I couldn’t decide between section Validae or Amanita either. I can say that the mushroom did not bruise red when I crushed the stem base, though I didn’t section it to look for reactions in the cap or flesh. I also only waited about a minute to check for discoloration.

I’d also like to thank you for the Amanitaceae site as well as the old NJCC one. They are invaluable resources to me! I used them nearly every day.

first photo is really nicely shown.

The first picture also seems to show a striate cap margin, but it is a little difficult to interpret. If your camera will permit you to close the aperture or slow the speed, you may be able to get greater depth of field…more of the cap in focus at the same time. You may need to stead the camera on a bean bag or a block of wood or a tripod or something. The level of detail is very nice; you just need to improve the amount of the image that is in focus.

I think the species will probably belon in either sect. Amanita or sect. Validae. The specimen is quite interesting. Do you dry specimens for preservation?
