Continning our earlier work on the action of fungi of the genus Gibberella on steroids we have shown that G. saubinetti (MONT. SACC. has the ability of hydroxylating steroids in the 6β- or the 15α-position. On the other hand, the steroid transforming properties of G. baccata (WALLR. SACC. seem to be limited to 15α-hydroxylation. Some interesting substrate specificity has been observed in this connection
