Small hypogeous gasteroid basidiomata, exterior light peach color, interior light yellow, composed of convoluted hymenium. Spores ellipsoid, rugulose, with small hilar appendage, 14–16 x 10.4–11 μm; walls 1.5–2 μm thick; starting light yellow, becoming brown. Basidia 34 x 9.4 μm; mostly 2-spored.
Partially buried in soil, on shaded slope dominated by manzanita, also with Eriodictyon, Prunus, and Ribes, with Quercus cornelius-mulleri about 20 ft away.
With Arctostaphylos.

Soil under Douglas fir.
On CADE, KOH yellow slowly fading to green
No distinct odor, mild flavor with very slight nuttiness, gleba and peridium yellow in KOH. Planted young scrub oak and chamise nearby. Ascosppores amyloid
Rodent digs found throughout the area exclusively under chamise. Manzanita also present, and interior live oak within 100 feet, but digs were only under chamise. Digging revealed that the mycelial mat that truffles were found in and smelled the same dissipated with distance from chamise. Melanogaster also mixed in and more abundant. Parts of the mycelial mat smelled like Melanogaster and parts smelled like these -- distinctly of oil paint. Woodrat nest about 8 feet away.
In canyon wall and soil clinging to underside of boulder with roots nearby, presumably belonging to the Quercus chrysolepis uphill. Alder and bay laurel also nearby, alder being downhill near the stream
Thanks for the ID and according to Christian also Gastroboletus turbinatus sensu CA
