“…However, much is still unknown about their edibility, properties and associated economic value. Similarly to most ECMF, Terfezia breeding programmes are based on the plantation of inoculated plants (Arenas et al, 2018;Louro et al, 2021;Morte et al, 2009Morte et al, , 2020. Terfezia mycorrhization (in vitro and ex vitro) and maintenance have been studied (Gutiérrez et al, 2003;Jamali & Banihashemi, 2013;Navarro-R odenas et al, 2012;Turgeman et al, 2016;Zaretsky et al, 2006;Zitouni-Haouar et al, 2014), and one method patented (Andrino et al, 2013).…”

“…Terfezia truffle production is seasonal and takes place in spring, in arid and semiarid regions (Morte et al, 2012). Terfezia claveryi and Terfezia boudieri have been successfully cultivated (Morte et al, 2017, 2020), and Terfezia arenaria cultivation in acid soils is currently under development (Louro, 2020; Louro et al, 2021). In addition, 16 other Terfezia species were found in the Iberian Peninsula (Table S2), opening new possibilities for Terfezia cultivation and exploitation.…”

“…Terfezia species are an example of successful cultivation of mycorrhizal fungi, achieved through a combination of biotechnology, for optimisation of fungal inoculum production, and forest management techniques (Louro et al, 2021; Morte et al, 2009; Morte & Andrino, 2014; Morte & Honrubia, 1992). Knowledge by local collectors and producers has been fundamental in understanding plant phenology as a key factor affecting desert truffle production, for example, the coincidence of the production season with flower blooming (Marqués‐Gálvez, Morte, & Navarro‐Ródenas, 2020).…”

Societal Impact Statement The planet faces a climate crisis with severe health, economic and environmental consequences. Political actions such as the European Green Deal aim to mitigate climate change by shifting production and consumption patterns, and the production of mycorrhizal sporocarps—the fruiting body of fungi—is no exception. The production of mycorrhizal sporocarps has a high economic, cultural and environmental impact in the Mediterranean region. With a key role in forest ecosystems, ectomycorrhizal fungi provide services and goods essential to maintain soil quality, ecosystem functions and food, contributing to the achievement of sustainable production and the European Green Deal goals—a climate‐neutral Europe. Summary Ectomycorrhizal fungi (ECMF) cultivation is an important economic activity in the Mediterranean region. Sporocarps from ECMF species such as Terfezia claveryi, Tuber melanosporum, Tuber aestivum and Lactarius delicious have been successfully cultivated. Due to biotechnological advances, a considerable evolution in ECMF cultivation techniques was observed in the last decade. New technologies and intensified Research and Development allow for a better understanding of the physiology of the plant‐fungi symbioses and how climate change affects them. Studying forest management practices is also essential to optimise the natural production of ectomycorrhizal sporocarps and help develop sustainable production practices. This knowledge revealed the importance of ECMF and their role in the rural bioeconomy and highlighted the need to establish sustainable cultivation practices. A successful example of ECMF cultivation is the production of Terfezia species, namely, Terfezia claveryi and Terfezia boudieri. Terfezia truffles are traditional delicacies with high socioeconomic relevance and numerous biotechnological applications. Furthermore, these Mediterranean native species are an important tool to develop the bioeconomy in rural areas by creating new production strategies. Furthermore, exploiting these and other native Mediterranean species can promote sustainable practices in line with new European Green Deal strategies, such as the Farm to Fork strategy, the EU Biodiversity strategy for 2030 and the Climate Law. This work reviews ECMF cultivation practices and forest management studies, presenting the case of Terfezia cultivation and how the sustainable production of wild and planted ECMF may contribute to achieving the European Green Deal objectives and to a more resilient Europe.

Truffles are the fruiting bodies of ascomycete fungi that form underground. Truffles are globally valued, culturally celebrated as aphrodisiacs, and highly sought-after delicacies in the culinary world. For centuries, naturalists have speculated about their mode of formation, and in cultures surrounding the Mediterranean Sea, many species have been prized as a delectable food source. Truffle fruiting bodies form underground and emit a variety of volatile organic compounds (VOCs). Truffle volatiles are believed to have evolved to attract animals that disperse their spores. The main VOCs identified from truffles include sulfur compounds, such as dimethyl sulfide (DMS) and dimethyl disulfide (DMDS); in addition, 1-octen-3-ol and 2-methyl-1-propanol have been found in most truffle species. Humans use pigs and dogs trained to detect truffle VOCs in order to find these prized subterranean macrofungi. Truffles have pharmacological potential, but until more reliable cultivation methods become available their high price means they are unlikely to see widespread use as medicinals.

“…Adhering to these these stipulations, we have developed a case study in Portugal, where until 2018 Terfezia richness was greatly overlooked, with only three species documented. Since then, five more Terfezia species have been recorded T. cistophila, T. extremadurensis, T. lusitanica, T. pini and T. solaris-libera (Bordallo et al 2018;Louro 2020;Louro et al 2020Louro et al , 2021 and the soil main features and putative host plant were registered. In the present work we reassess the diversity of this genus and characterize Terfezia ecology within the framework of ecological preferences, while also probing the intraspecific variability of the Terfezia taxa in analysis.…”

Developing below the soil surface desert, truffles are hard to find. Within Terfezia genus, at least 18 species are described and many are endemic to the Mediterranean basin. Ecological and geographic information are key factors for species diagnosis, and so far Terfezia species are believed to be linked to either acidic or basic soils or to specific plant hosts. Thus, we have looked at Terfezia diversity within a relatively homogeneous geographical area in Portugal that is suitable for these species and that covered different soils and different dominant host species. We analyzed the observed intraspecific variability within the context of species ecological preferences (e. g. edaphic and putative host). One of our major findings was the discovery of T. grisea in acid soils in association with Tuberaria guttata, a puzzling information since, until now, this species was only found in alkaline soils. We also report on the linkage of different Terfezia lineages within species and ecologic parameters such as soil texture, soil pH and plant host. Additionally, by placing the collected specimens on the most recent genus phylogeny based on the ITS region, we also updated the number of known Terfezia species occurring in Portugal from three to ten. Terfezia dunensis is here reported for the first time for Portugal. Overall, our results show that the exploration of undersampled sites reveals itself as a good strategy to disclose unknown aspects of desert truffle diversity and ecology. These aspects are of prime importance when considering the economic value of the desert truffles for rural populations in the Mediterranean basin.
