The knowledge of the host diversity in the Tuber genus, an economically important group of ectomycorrhizal fungi, is of crucial importance for efficient cultivation system establishment. Centuries of field observations as well as scientific researches provided the information on ectomycorrhizal associations formed by these interesting fungi. Besides this, some recent works indicate that Tuber mycelia may be associated not only with roots of woody plants traditionally considered as ectomycorrhizal hosts but also with root tissues of herbaceous plants and with some kinds of soil organic matter. At the same time, some species of the Tuber genus tend to form scarce ectomycorrhizas. These facts suggest that Tuber mycelia may exploit some auxiliary sources of nutrition in a commensalistic, parasitic, or necrotrophic manner. This would make the concept of the host in the Tuber life cycle more complex than just a source of the nutrition provided via ectomycorrhizas. A possible change of the host concept in Tuber symbiosis may result in an increase in the host diversity, compared to the diversity based on the concept that is recently accepted.
