Don't ingest these unless you are sure bro. Do your research and be 100% of what you are ingesting. To my knowledge there are only a few similar species to the psilocybin carrying mushrooms that are toxic and they are fairly easy to distinguish but better safe than dead or sick as fuck. If you don't have it already the Audubon Society Field Guide to Mushrooms is a great book giving you pictures, similar mushroom species (toxic ones included), spore print information and geographical information. Check it out it's a great read.
Edit: Whoops just saw you're from ireland. The Audubon Society book only covers North America, there's probably an equivalent or something close over on your side of the world though.
