(Shore 2013). Further, summer temperatures showed a clustered distribution (Fig. 3) with temperatures being lower (18.98°C vs 21.73°C) in sites that do not have a history of natural Tuber melanosporum populations (T =3.4877, df = 33, p<0.05). These differences are displayed in figure 4. and have significantly expanded the range of conditions that we now know to be suitable for fruiting (Table 1.). This data is now a useful reference for scientists and truffle cultivators worldwide.
