As to the mushroom you inquired about, my first thought was this:
The spotted cap and ring are something I watch out for hereabouts, as Amanita pantherina is one of the deadliest mushrooms in the world. However, your pic (although it's absolutely impossible to tell from a pic on the internet) seems to have a more yellow color than A. pantherina.
In that case, I dunno.
Don't eat it.
Paul stamets ate a pantherina once and had a crazy trip. Sounded like a nightmare.
The lad is mad. Imma stick to whiskey.
I can imagine the effects of the mushroom permanently changing your brain chemistry.
Here's the description of the patherina experience lol.
