Re-investigation of the type material of beraunite from the Hrbek Mine, Svatá Dobrotivá, Czech Republic, proved the identity of beraunite and eleonorite. Based on this study, the mineral eleonorite was discredited, and the ideal formula of beraunite was redefined from Fe2+Fe3+5(PO4)4(OH)5.6H2O to Fe3+6(PO4)4O(OH)4.6H2O. Refined unit-cell parameters were obtained from powder X-ray diffraction data of the original material of Friedrich August Breithaupt.
