A new tetracyclic triterpenoid acid, sulphurenic acid, has been isolated from the mycelium of the fungus Polyporus sulphureus grown in both surface and submerged culture, and its structure determined as 15α-hydroxyeburicoic acid (II). It represents 25% of the total steroid content of P. sulphureus , the remaind erbeing eburicoic acid. Ergosterol has been isolated from the lipid fraction of this fungus.
