Figure 5From: Comparative phylogenies and host specialization in the alder ectomycorrhizal fungi Alnicola, Alpova and Lactarius (Basidiomycota) in EuropeMapping of sampled sites for sporocarps in Western and Central Europe (for details see Additional file 2). Colour of circles indicates tree species; green: Alnus alnobetula; black: A. cordata; red = A. glutinosa; blue: A. incana. Large circles: at least three species sampled (sites visited for this study); small circles: one or two species sampled (occasional visits on sites or collections sent by correspondents).Back to article page
