Figure 3From: Comparative phylogenies and host specialization in the alder ectomycorrhizal fungi Alnicola, Alpova and Lactarius (Basidiomycota) in EuropePhylogenetic 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.Back to article page
