The book "True Truffle (Tuber spp.) in the World" offers a comprehensive examination of the taxonomic diversity of the genus Tuber, known for its economically significant truffles. This specialized book features contributions from internationally recognized scientists who explore various aspects of truffle systematics, interactions with abiotic and biotic environments, and the molecular processes in truffles. The topics covered range from evolutionary theories and the phylogeny of Tuber species from Asia, Europe, and North America to the climatic influences on the natural distribution and fruiting body production of Tuber species. Additionally, it discusses tools for tracking truffles in the soil, host diversity, and the relationships between small mammals, wild boars, and truffles. This book serves as a valuable reference for researchers in the fields of mycology, ecology, and soil science, and is also of interest to farmers and foresters involved in truffle cultivation.
