Observation 27569: Rhizopogon occidentalis Zeller & C.W. Dodge

For 8 days have kept this specimen in a bucket which had also had perhaps 1/2 inch of rainfall collected at the same time: a damp day for the Oregon coast. Was out of the car less than 20 minutes, but thoroughly soaked by then. Peridium shows the darker reddish-brown major rhizomorphs, which climb the peridium, but also shows the yellowish-orange secondary rhizomorphs and yellow (becoming whitish with age) felt-like fibrils or rhizimes enclosing the gleba. Quite immature when first collected, apparently washed out of its sandbank and deposited in a small sandbar of a d(rain)age ditch. Visible holes near base of sporocarp indicate sclerid fly larvae, which love Boletus, Suillus and Rhizopogonaceae. This specimen developed an aroma in extreme age: ripe pear. Usually I smell bananas from this truffle, but pear is a close second with over-mature specimens. Usually associated with Lodgepole (aka Shore) pine.
