In our search for new cyathane metabolites related to the biosynthesis of erinacine Q in Hericium erinaceum, we isolated a novel cyatha-3,12-dien-14β-ol named erinacol together with known 11-O-acetylcyathatriol (the erinacine Q aglycon) and new metabolite 11-O-acetylcyathin A₃ from the mycelial extract. The structure of each compound was determined by spectral methods. Possible biosynthetic relationships of these metabolites are discussed from their structural features.
