we don’t have many eucalypts. Few can withstand our typical winter, and die out. For the few that can stand our winters, they are usually overtaken with other mycorrhizae.

I think I read (somewhere) that Pisolithus is often associated with acacia and eucalypts. Several Pisolithus are from Australia and New Zealand; others are from Africa.

California eucalpts are so common they are often planted next to freeways and as fast-growing replacement trees for drier climates. I know some eucalypts are found in extreme Southwestern Oregon. I don’t know which species or varieties these are.

two different species with Eucalyptus. The ones I found in LA this past spring appeared to be the newly described Pisolithus croceorrhizus. They were growing under Corymbia citriodora (=Eucalyptus citriodora).

Nope, no other significant trees there. Are all the eucalyptus ones in the west supposed to be the same species?

probably no Pisolithus arrhizus here in the west anyway

This is almost certainly an exotic Pisolithus. This species is common with Eucalyptus throughout California

Interesting.

Eucalypts are one of the most common Pisolithus hosts, but not for native Pisolithus (Pisolithus tinctorius = P. arrhizus).

was right there for sure. I’ll check whether there was anything else.

Pisolithus is 100% mycorrhizal.

Possible hosts?
