      abstract     = {The functioning of ectomycorrhizal (ECM) symbioses is
                      closely related to the development of the soil mycelial
                      phase the ECM fungi. The properties and spatiotemporal
                      dynamics of such mycelia in ecosystems is, however, poorly
                      understood. Here we show, using a soil colony of summer
                      truffle (Tuber aestivum) as a model, that an ECM mycelium
                      may only grow and colonize newly-opened soil patches when
                      soil temperatures rise above certain threshold, in this case
                      +10 °C, provided other requirements such as sufficient soil
                      moisture are fulfilled. Extension rates of truffle mycelium
                      in the fields was recorded as >0.3 μm min−1, several-fold
                      greater than that predicted from laboratory cultures.
                      Further, we demonstrated that there was a consistent spatial
                      differentiation in mycelium growth patterns within the
                      fungal colony on a decimeter scale, changing from
                      “diffusion” type of growth at the colony margin to
                      “colony-front” pattern further away from the colony
                      margin. This change was clearly accompanied by shifting
                      structure of soil microbial communities with Terrimonas sp.
                      and another unidentified bacterium correlating with the
                      “colony-front” mycelium growth pattern, and Sphingomonas
                      sp. and Lysobacter brunnescens with the “diffusion” type
                      of mycelium growth. Possible implications of the observed
                      truffle colony differentiation are discussed for processes
                      like fruit-body formation and dispersal of this ECM fungus.
                      Our data indicate that the thallus of T. aestivum has to be
                      considered as a principally variable (“mutabilis”) being
                      in space and time, whose behavior correlates with conditions
                      in ever changing soil environment (“in mutabili”).},
