title: Postiaalni Niemelä & Vampola (Basidiomycota, Polyporales) - member of the problematic Postiacaesia complex - has been found for the first time in Hungary.
abstract: Due to their bluish basidiocarps the Postiacaesia (syn. Oligoporuscaesius) complex forms a distinctive morphological group within the polypore genus Postia Fr., 1874. Five species of this group occur in Europe: Postiaalni Niemelä & Vampola, Postiacaesia (Schrad.) P. Karst., Postialuteocaesia (A. David) Jülich, Postiamediterraneocaesia M. Pierre & B. Rivoire and Postiasubcaesia (A. David) Jülich. In this study Postiaalni is reported for the first time from Hungary. The dichotomous key of the species of the European Postiacaesia complex was prepared as well.
