The generic separation of Oudemansiella and Xerula is discussed and accepted as proposed by Dörfelt. Xerula caussei and X. kuehneri are redescribed and illustrated. Xerula nigra and X. renatii are considered conspecific with X. caussei. Dactylosporina is reduced to the synonymy of Xerula. The new combinations X. steffenii and X. macracantha are introduced.
