uotside near my house i found some mushrooms Psilocybe semilanceata and i thought that i should try them so i want to ask if someone know how much i have to eat for normal trip (fresh or dry)
Semis are much stronger than P. Cubensis. I would recommend about 15grams fresh or 1.5 dry for a fairly strong trip.
so i tooke some photos of them please help me to find out are they realy Psilocybe semilanceata (i want to be sure before eating them)
shroomery.org has a dosage calculator though i am not sure how accurate it is, but its a good site so i'd trust itd be quite good. http://www.shroomery.org/index.php/par/12195
lol i strongly doubt those are liberty caps (semilanceata). the cap is not at all similar, and neither is the stem... compare this to your picture, it is not at all the same, first of all the cap is completely different, the caps on your pic are flat. and most IMPORTANTLY, semilanceata gills (the lines underneath the cap) are supposed to be black and not white. I would recommend you to do further research, shroomery.org is an exellent site to figure out the type of shroom you have, but in my opinion this is not a psilocybe.
They might be. The stems make it hard to tell though. Make a spore print. Put a cap gills down on a sheet of paper for a few hours...see the color. Also look for some bruising after you handle them on the stem or cap sometimes same species of mushrooms differ from area to area
