The only Pisolithus species which has been confirmed for Oregon

at this time is Pisolithus arhizus (old name = Pisolithus tinctorius). While other Pisolithus have been identified in the world, they are associated with acacia or eucalyptus, neither of which either survives here, or survives for more than 2-3 years, if lucky. That being said. Pisolithus arhizus is also found in Europe, and this was possibly associated with beech.

Let’s start with Alexander H.

Are you asking if DNA work has been done on them yet? I don’t think so. I rather doubt DNA testing had been started during Alexander H. Smith’s time. Still, he did have that trick eye, that could see spores with.

Who’s determining that all the OR specimens are P. arhizus?

Tuberale, why are you confident this one actually is P. arhizus?
