Figure 3

Phylogenetic reconstruction of the Alpova lineage (Paxillaceae) based on ITS, showing putative evolutional events in relation with host specificity. Red: species associated with Alnus sect. Alnus. Green: species associated with Alnus sect. Alnobetula. Brown: species associated with alders of both sections. Red star shows putative basal association with Alnus sect. Alnus. Arrows show events of speciation associated with host specificity; red arrow: host-dependent radiation with Alnus subgen. Alnus; green arrow: host shifts from Alnus subgen. Alnus to A. alnobetula.
