Should then limit to only collections in North America, Europe or found in exotic pine plantations in Africa where both the potential hosts are known, include oaks or pines and without any other potential hosts like Cistus, Eucalyptus or other present.

Or we could limit it to taxa around P. arhizus, “species 4” and “species 5” from ‘Phylogeography of the ectomycorrhizal Pisolithus species as inferred from nuclear ribosomal DNA ITS sequences’.

These 3 species form a nice genetic group and are the only ones that included in that study that occur with pines or oaks. Although “species 5” is an Asian species that also occurs with Eucalyptus while “species 4” is European found with oak and pine in Mediterranean countries. I wonder if this pattern would continue to hold with a more comprehensive genetic tree.

to distinguish chocolate-spored (== non-Eucalyptus) observations.
