You must know which to pick, and only those. Sorry, for the bad news.
Two mushrooms commonly mistaken: Amanita phalloides (generally pronounced /æməˈnaɪtə fəˈlɔɪdiːz/), commonly known as the death cap, is a deadly poisonous basidiomycete fungus, one of many in the genus Amanita. Widely distributed across Europe, A. phalloides associates with various broadleaved trees. In some cases, death cap has been accidentally introduced to new regions with the cultivation of non-native species of oak, chestnut, and pine. The large fruiting bodies (i.e., the mushrooms) appear in summer and autumn; the caps are generally greenish in color, with a white stipe and gills.
Tricholoma equestre or Tricholoma flavovirens, also known as Man on horseback or Yellow knight is a formerly widely eaten but hazardous fungus of the Tricholoma genus that forms ectomycorrhiza with pine trees. Known as Grünling in German, gąska zielonka in Polish, and canari in French, it has been treasured as an edible mushroom worldwide and is especially abundant in France.
But, let`s be frank. Despite certain similarities, there are so many differences between them that only a completely ignorant or drunk person may mistake them with each other.
In Polish culture, the symbol of a deadly mushroom is red mushroom/fly amanita. It is visualised everywhere: in school books and projects, board games, in fairy take graphics, on posters etc. However , it is not so dangerous after all - causes hallucinations and mild disorder, not death. Why does it play the role of a black character? Because of its beauty.
en.wikipedia.org/wiki/Amanita_muscaria Fly agarics are known for the unpredictability of their effects. Depending on habitat and the amount ingested per body weight, effects can range from nausea and twitching to drowsiness, cholinergic crisis-like effects (low blood pressure, sweating and salivation), auditory and visual distortions, mood changes, euphoria, relaxation, ataxia, and loss of equilibrium.
In cases of serious poisoning the mushroom causes delirium, somewhat similar in effect to anticholinergic poisoning (such as that caused by Datura stramonium), characterised by bouts of marked agitation with confusion, hallucinations, and irritability followed by periods of central nervous system depression. Seizures and coma may also occur in severe poisonings. Symptoms typically appear after around 30 to 90 minutes and peak within three hours, but certain effects can last for several days. In the majority of cases recovery is complete within 12 to 24 hours. The effect is highly variable between individuals, with similar doses potentially causing quite different reactions. Some people suffering intoxication have exhibited headaches up to ten hours afterwards. Retrograde amnesia and somnolence can result following recovery.
