Yes, there are poisonous mushrooms that are eerily similar to mushrooms that contain psilocybin. [1] Depending on its stage of growth, they can be easily confused, especially by a newcomer.

There is one main rule to foraging. "Never eat a mushroom you can't positively identify." If any trait of it's appearance is questionable, don't eat it.

This is inaccurate or out of date or both. Some species of Psilocybe look just like Galerina and sometimes grow right next to them.
