Pisolithus arhizus group, you will find a link to an observation wherein Else Vellinga explains that P. arhizus is most likely not a North American species.

Clarification, please.

Exactly what other species of Pisolithus arhizus group have been described from Oregon? Please be specific, and include where in Oregon it was found. Until I hear otherwise, I will continue to call this Pisolithus arhizus.
