In continuation of our earlier work certain fungi were detected which are capable of hydroxylating steroids at further carbon atoms of the nucleus. These microbiological procedures have made possible the preparation of new cortexone derivatives with an additional hydroxyl group in 7α-, 15α- or 15β-position. The elucidation of the constitution of these compounds by degradation and chemical connection
