Xerocomus truncatus Sing., Snell et Dick is recorded for the first time from Czechoslovakia in several localities in the vicinity of Prague and is transferred to the genus Boletus. The nomenclatural status of the invalid name Xerocomus porosporus Imler is also discussed. Boletus lanatus Rostk. is here considered as a variety of Boletus subtomentosus L. ex Fr. and the correct name is therefore Boletus subtomentosus var. leguei (Boud.) Bataille.
