do not eat those they are poisonous

I'm fae Scotland too, its the liberty caps your real wanna look out for if you want a trip, they are the safest and easyest to identify. These look very familiar you may find some liberty caps near by.

they look like pan. foes.to me. very identical too panaeolus cinctulus(active)

if spore print is dark-purple brown then its pan. foenisecii

if it is jet black  wich i doubt ,its pan. cinctulus

looks like haymaker mushrooms. mildly psychadelic and poisonous. according to my shroomguide

I have seen these exact type of mushroom in my backyard by a tree stump and all over the grassy area around the stump. Chicago area.

im not sure. but a trusted identifyer would be able to tell you, if you post a id request in the mushroom hunting and identification board. http://www.shroomery.org/forums/postlist.php/Board/3
