Biodiversity of Hypogeous Fungi in Basilicata

Abstract

During the last two decades, systematic studies were carried out on biodiversity of hypogeous fungi in forestry territories of the two Basilicata (southern Italy) provinces, Matera and Potenza. Identification of fungus taxa found in the region was commonly accomplished on the basis of macro-and microscopic features, and only in a few instances, molecular analyses were utilized. Thanks to these investigations, Basilicata now occupies, among Italian regions, the first and fourth positions for number of Tuber species, varieties or forms and total number of hypogeous fungi (Ascomycota, Basidiomycota and Zygomycota) naturally growing in its woodlands and Mediterranean maquis areas. In fact, the last up-to-date acquirements on the topic bring up to 29 and 53 the number of Tuber taxa and that of the other hypogeous and semi-hypogeous (only three entities) fungi present in the region, respectively. In this chapter, the essential information regarding these fungi is given, so updating to 2014 the relative available knowledge. Among the Fungi, object of this review, the Ascomycota Pachyphloeus conglomeratus and Tuber malençonii, the Basidiomycota Hymenogaster decorus, H. hessey, H. rehsteineri, Schenella pityophilus and Myriostoma coliforme as well as the Zygomycota Youngiomyces multiplex deserve a particular mention because of their rarity.
