Rank Reasons
This species appears to be endemic to the Great Basin and neighboring areas. It is known from only 4 collections which are geographically widely separated. As truffles go this one is relatively conspicuous so the low number of sites and collections is significant. More information is needed to be certain about the status of the species.
Range Extent Comments
Known from Deschutes Co., Oregon; Valley Co., Idaho; and Washington Co., Utah
Occurrences Comments
Truffles have been studied in western North America for over a hundred years. This species, however, is known only from four sites in three states (FSL n.d., Fogel n.d.). The site from Jackson Co., Oregon, cited in Castellano et al. 1999, was not backed up by a collection cited under this name in the web sites of either OSC (n.d.) or FSL (n.d.).
Threat Impact Comments
With three known sites in spite of many years of work in all three regions, this species is threatened by any changes in the sites, e.g., development, logging, mining.
