The contribution is devoted to the distribution of Amanita friabilis (P. Karst.) Bas and to its old-new records in Bohemia. In the Czech literature, this fungus was described in 1920 by Velenovský under the name Amanita sternbergii (location: Pecný near Ondřejov, Central Bohemia district); Bas (1974) considers it identical with A. friabilis (P. Karst.) Bas. It is a fungus belonging to the subgenus Amanita, section Amanita, and is systematically closest to A. gemmata (Fr.) Gill. It is characterized by the grey-brown colour of the striated cap, similarly coloured felted remnants of the volva, the ringless and scaly stipe, the mealy fragile, soon disappearing volva and its rare occurrence in alder groves. Recently, it was again collected in Bohemia (after 60 years) at three localities in the Central and West Bohemian districts (1979, leg. E. and W. Lippert). The species is known from nine localities outside Czechoslovakia.
