Amanita parcivolvata

Amanita caesarea


Relocating that copperhead snake reminded me how that hillside seems more prone to wild mushroom growth.

We spotted this Amanita parcivolvata on our way back, also known as a False Caesar's Mushroom.

It's unclear if these are okay to eat. I won't be risking a taste test unless we get more conclusive data.

It's good to be cautious with wild mushrooms, I think. Every autumn I see a lot of mushrooms popping up, so I did some research into edible wild species. I found that it could be surprisingly hard to distinguish edible spcies from poisonous ones. So I decided to give wild mushroom gathering a miss.

But there are some test that you can do. A large number of potentially lethal mushrooms contain amatoxins, which can be detected by the Meixner test.

Look at it - it screams out I am so pretty - I AM UGLY!!!! It taunts you to pluck it all the while boasting the ominous RED glare. RED is for Stop for a reason!

Roland --- Yep, we only eat the really obvious edibles that don't have any scary lookalikes.

Fostermamas --- I agree! There's something so enticing about the colors, shapes, and textures of mushrooms.

Jayne --- I'm with you --- bright red in nature is often a sign of poison.

I'm pretty sure I caught that Amanita parcivolvata at its youngest and brightest point...I went back a few days later and its top expanded out and upwards and over half the redness seems to have been washed away.

@Jayne: The color of mushrooms is not a reliable indicator of danger. E.g. the edible Ceasar's mushroom is brightly colored, while the lethal destroying angels are plain white.

The 1987 edition of A Field Guide to Mushrooms (Peterson Field Guides) refers to Amanita parcivolvata as "Flimsy Veil" and says that it is "Reported poisonous" but gives no source for this "report".

On the other hand, I found this comment made three years ago on a blog.

"I once cooked about 5 Amanita parcivolvata mushrooms in a large multi-mushroomed dish for about 5 or 6 friends of mine. I thought they were Amanita jacksonii. It was only after eating it that I realized my mistake, and my heart sank and I had to go around to everyone and apologize profusely. People looked at me blankly because they just didn't know how to react. How do you react to news like that?

"Anyone, none of us experienced even the least of symptoms. No gastric upset, no uncomfortability, nothing. So barring any long-term kidney or liver damage (which seems unlikely to me), Amanita parcivolvata seems perfectly safe." https://www.shroomery.org/forums/showflat.php/Number/10751687

Back to the field guide. It says that parcivolvata lacks the distinct volva of jacksonii, which is edible and delicious, and it also lacks the characteristic ring around the stem. So if you see those two features very distinctly, and it looks otherwise like the pictures you see on this webpage, you should be safe.
