I think so, Lucy.

While I have only read about these, the photos are exceptional IMO. The linear thingy in the center of the sporocarp is called a columella, and is the remants of a stipe. Haven’t followed recent research into these, but it is either starting to form a columella or is in the process of losing it. As such it is a fascinating example of a mushroom becoming a truffle or the other way around.

The relationship to Cortinarius means this should be collected and photographed, but NOT eaten. Some of the hypogeous Cortinarius in Oregon are quite poisonous.

Not sure

… but I have added a photo that shows some orange on the surface of one (see added image). Would that be the kind of staining shown by Descomyces?

..was there any yellow-orange staining on the surface of the fruit bodies, if yes then this is most likely a Descomyces species, a gastroid form of Descolea.

Molecular studies have shown that species in the former genus Thaxterogaster can be associated with subgenera of Cortinarius which shows that these interesting gastroid fungi form a polyphyletic group within the large genus Cortinarius.
