Threat ImpactHigh
Rank Reasons
The taxon has small populations, unique and limited habitats, and is found on only one or two species of truffle.
Occurrences Comments
Probably fairly common.
Threat Impact Comments
Threatened by limitations in habitats, primarily with moderately aged douglas-fir. Vector to spread the fungi to the tuffles is unknown, but likely an insect. Limitations in this vector may cause problems.
