Some species of mycorrhizal fungi have been observed to have a fascinating stress response to being exposed to a new soil/environment. The mycellium will somehow ramp up it's rate of HGT (horizontal gene transfer) and therefore borrow genes from other soil organisms in that soil. These genes are borrowed across phylums from even bacteria or microalgae. Essentially, it's a natural mechanism to rapidly increase its rate of evolution.
