Comments: Also ironically known as the "Gentle Cort". In Europe this mushroom is reported to contain deadly toxins; it is related to species such as the Poznan Cort C. orellanus that are known to have caused fatalities. Consequently, the mushroom hunter is warned not to eat any "LBMs", or little brown mushrooms. Eating this mushroom and closely related species typically involves life-threatening kidney failure, symptoms usually do not appear until 3 days to 2 weeks after ingestion.
