New aminoacids, L-3-(2-carboxy-4-pyrrolyl)-alanine () and L-3-(2-oxo-5-pyridyl)-alanine (), were isolatedfrom and their structures were deduced by spectral data and biogenesis and confirmed by syntheses. Stizolobic acid () was also found in this fungus.
A new amino acid, L-3-(2-carboxy-4-pyrrolyl)-alanine was isolated from Clytocybe acromelalga. Its structure was determined by spectral data and a synthesis.
