Truncocolumella citrina has a yellow felty peridium and the gleba is gray to olive or brown, chambered, with a distinctive pale yellow to yellow columella. The spores and most other features are very similar to to those of rhizopogons; the major difference is the presence of a columella. T. citrina is common under Douglas-fir on the west side of the Cascades crest and also extends into interior conifer forests as far as the Rocky Mountains. The potato-like fruitbodies often be found partially exposed at the surface of the soil or litter.
