Observation 35026: Rhizopogon vinicolor A.H. Sm.

This is a common mycorrhizal hypogeous fungi associated with young stands of Douglas fir. While it can fruit at almost any time of year, it is most common during the spring and fall. Easy to cultivate, inoculation with seedling Douglas-fir seedlings just before planting increases seedling survival after transplantation. Three applications within 1 month of planting nearly guarantees seedling survival at elevations below 2,000 feet. Note the rope-like rhizomorphs (root-like structures) attached to the peridium (outside).
