Figure 1.

Geographic origin of the Armillaria cepistipes populations sampled in the Alps (Switzerland) and in the Carpathian mountains (Ukraine). In the lower left part of the figure, the Alpine population is shown, with the white drops indicating isolates of the North subpopulation and the green drops isolates of the South subpopulation. In the lower right part, the Carpathian population is illustrated, with the blue drops representing isolates sampled within plots (a zoomed example is shown) of the Beech subpopulation and the orange drops isolates within plots (a zoomed example is shown) of the Mixed/conifer subpopulation.
