Pleurotus nebrodensis (Basidiomycota), a rare endemic mushroom of Sicily: current and future issues

This paper deals with the basidiomycete Pleurotus nebrodensis, one of the rare examples of endemic fungi in Italy and Europe. After clarifying the taxonomy of this taxon, including a comparison with a species from China misidentified as “Pleurotus nebrodensis”, we describe the characteristics of its natural habitat, and provide a new morphological description and information on its pilot-scale cultivation, current conservation status according to IUCN criteria and conservation strategies. New ITS region sequences were deposited in GenBank. Furthermore, the antibacterial and anti-cancer properties of P. nebrodensis are mentioned, making it a potential medicinal mushroom. Finally, a critical analysis, on a phylogenetic basis, of the Italian production of substrates inoculated with “P. nebrodensis” strains is also included.
