What is the onset time for symptoms of Inocybe spp. poisoning?

The onset time for symptoms of Inocybe spp. poisoning is typically within 15 to 30 minutes after ingestion. This relatively rapid onset is due to the presence of muscarine and other toxins found in Inocybe mushrooms, which can stimulate the parasympathetic nervous system. This stimulation leads to a range of symptoms including salivation, sweating, gastrointestinal distress, and potentially severe respiratory problems.

The quick appearance of these symptoms is crucial in distinguishing Inocybe poisoning from other types of mushroom poisonings, which may have varied onset times depending on the specific toxins involved. For instance, some mushrooms may take hours or even days to present symptoms, while Inocybe's quick response can indicate severe toxicity, necessitating prompt medical attention. Understanding the timing helps in diagnosing and treating mushroom poisoning effectively.
