Observation 189264: Boletus eastwoodiae (Murrill) Sacc. & Trotter

When: 2014-11-22

Seen at: Sonoma Co., California, USA [Click for map]

Who: Darwin BondGraham (darwin)

No specimen available

This bolete was found on a ridge (not more than maybe 100-200 feet in elevation) in a hilly area growing under coastal live oak with some deciduous oak, madrone, manzanita and occasional fir trees growing nearby. It was growing East of Santa Rosa, so not coastal. Definitely growing under and associating with the live oak. We found several other specimens growing under live oak without other tree species near. We did not find any growing in clusters.

Fruited recently after moderate to heavy rains. The context is yellow and bruises blue when cut. The stipe is white with faint reddish-pink color. The pileus is rosy pink. Stipe is very bulbous toward the bottom.

Anyone got an idea about ID? My best guess is “butter bolete.”

I think you’re right. It’s eastwoodiae. I just cut the specimen in half and it bruised brilliantly blue in about 30 seconds. Strangely when I originally collected it a few days earlier it didn’t bruise blue when I cut the stipe. Only the pores bruised.
