small?

micro-characters would help for a specific ID.

similar in macro possibilities: G. arenosa, G. arenicola, G. clausa (found in riparian areas, esp. w/willow, semi-arid regions of the west).

this likely is much more widespread. When I purchased Mushrooms Demystified in 1987, I asked David where he had found this (and Tuber separans). In return David photographed fresh Tuber species from Paul Bishop’s Tree Farm.

David said Geopora arenicola was not at all uncommon, but commonly overlooked in California. It looks so much like a hole in the ground, he named it that. Truffles are like that: far more are stepped on than found.

David also told me he had found the entire collection of T. separans under a single California live oak tree (photo 212). Odd other collectors from California have not reported it.
