New aminoacids, 3-(6-carboxy-2-oxo-3-pyridyl)-L-alanine, 3-(6-carboxy-2-oxo-4-pyridyl)-L-alanine and N-[2-(3-pyridyl)ethyl]-L-glutamic acid were isolated from the poisonous mushroom and their structures were determined. Their occurrence in this fungus supports the previously proposed biogenesis of acromelic acids.
