The author reports a finding of a resupinate polyporaceous fungus Fibroporia radiculosa (Peck) Parm. in Czechoslovakia. The forest "Panský les" near Zbilidy in the district Jihlava in the western part of Moravia is a new locality of this rare species (leg. et det. P. Vampola, 15th August 1991, PRM 874087, MJ 227/91). This striking yellow Poria grows saprophytically on dead conifers and rarely on hardwoods. Till now it was known only froir North America, i.e. from Canada, USA, Costa Rica and Jamaica. Except Czechoslovakia this fungus grows in Europe in Germany and Austria too but there it has been by mycologists determined as Poria saxonica Dorfelt.
