They grow under and around rhoderdenrons planted in association with alder and sometimes alder and willow muclch, as do azurescens and cyanofibrillosa.

In the early 1980;s someshroomsers I met at a conference at Breittenbush Hot sSprings in Orgon had boasted of picking close to three hyndred pounds of P. cyanescens and P. cyanofibrillosa alongside highway I-5 between Eureka and Arcada< California..

I have only found them a few times around rhoderdendron, but that is only on e of their habitats.

They need other nutriets to grow although they are mychorizial to socertain plants in their environment.

Good luck in the fall.
