Why is consuming unidentified mushrooms dangerous?

Consuming an unidentified mushroom is like playing Russian Rolette. Some species of mushrooms contain toxins that cause a prolonged excruciating violent illness, which ends in liver failure and death.

Other poisonous species can make you so sick that you wish you were dead!

It should be noted that, in urban and woodland habitats, deadly mushrooms are FAR more common than psychoactive species. Deadly species can also be found in pastures, and the highly toxic Chlorophyllum molybdites is especially common there.

To the untrained eye, many poisonous mushrooms resemble psychoactive or culinary species. Every wild mushroom should be considered deadly poisonous until proven otherwise.
