Aurantiporus croceus, a flagship species of the European fungal conservation is re-discovered after half century in Hungary

The threatened polypore, Aurantiporus croceus has previously been known only from one locality in Hungary, and the basidiome of this species has not been seen in the country since 1972. In this study, a new Hungarian finding of A. croceus is reported from an old-growth forest reserve in the Vértes Mts (Central Transdanubia). We present the nrDNA ITS sequence, macro- and microscopical characteristics as well as photographs of the new specimen.
